My Thoughts & Experience Regarding Exhaust Systems

I'm seeing a lot of action in the new and used exhaust system market 'round these parts lately and many ideologies, thoughts and expressions regarding such that simply don't wash.....with me....so please...if I express something here which you as a reader find offensive....please excuse my "shoot from the hip" editorial stylings as...that's just me...so without further adue?...here goes...

SLIP-ON/BOLT-ON VS FULL SYSTEMS:

I'm a huge advocate of Full Exhaust Systems over SO's and here's why....

Reason #1. Both will give your exhaust note a tune for the better but the equality (and I'm being nice there cause I ain't heard a S/O yet that sounds as good as a full system) ends there and where the S/O's end off?...The Full Systems pick up and run with advantages such as greatly diminished weight and a great big barn door to let ALL them ponies loose. So in essence?...there's really 3 good reasons here as the full systems typically a. sound better, b. weigh waaaaay less annnnd...c. put out more power.

Reason #2. Spending good money after bad sux almost as bad as 1/2 measures when it comes to exhaust systems and it's been my personal experience (1 time) that I ever bought a slip-on only to be dis-satisfied (for many of the reasons in reason #1 above) within a few months of mounting the S/O only to then purchase a full system and incurr all the "Re-tuning Costs" yet again which are consistant with such changes as you get to pay for proper tuning twice as well....end of story on that issue....and now onto...

WHAT TYPE OF FULL SYSTEM SHOULD I BUY?:

Basically there are 4 primary types of "full exhaust systems" out there which can be classified and defined as follows...

"Type #1. 4/1"and is my personal favorite for any "streetbike" as while it yeilds substancial power gains up top?...it still retains a strong low-range usually accompanied with vastly enhanced mid-range power as well...and imnsho?..all three are important power catagories for a street going bike.

"Type #2. 4/2/1" in my experience typically offers up optimum top-end but usually comes at the cost of a noticably huffier bottom-end in a robbed peter to pay paul scenario

"Type #3. 4/1/2 and/or? 4/2/1/2" imho is both cool looking but...silly from a performance (and cost) standpoint as while the duallies coming out the back "look cool"?...you probably paid far more and...got more...more weight...which in this rare case?..."more" is in fact...."less"..butcha still got to pay "more".

"Type #4. Drag Pipes/Sidewinder/Megaphone" Purpose built indeed...but....for one purpose...one...single purpose...but what they do they typically do extremely well when properly tuned however....not for me...I like to lean to the right every now and then.

MANUFACTURERS & MATERIALS:

At one time in my life I took direct issue with Yoshimura regarding this very topic as some internet viewers (Fellow FZ1OA Bretheren) took notice and made comment at how crappy looking my head pipes appeared...and they were correct...my yosh headpipes were in fact all stained up...after just less than a year of use...despite that I myself had mounted them and took extreme care in completely and thouroughly wiping them down with isopropyl alcohol before the first fire-up...and they looked great for about 6 months and then the staining gradually began to appear..deep staining...and me being a lifelong machinist/fabricator by trade I consulted a thermal engineer/metalurgy specialist at my place of employment who identified the staining as..."Carbon Precipitation"...which occurs in the lower grade 300 series stainless steels such as the 316 which yosh uses...emails rained into yosh....yosh execs called me...bragged about how many systems they manufacture and sell each month and then offered me a free replacement system which arrived to my home overnight...and guess what happened to the 2nd free system less than a year later?....you got it..."Carbon Precipitation Staining Of The Headpipes"...and what I can't understand is why a huge multi-million dollar corp. like yosh gives their consumers 316SS while poor little old Rob Muzzy pumps out SS systems made of 347 grade SS...as I had one of his megaphones on my old ZRX1100 for a couple years and 20,000+ miles and while it turned this pretty Straw/Gold color?...it NEVER showed the first little sign of any carbon precipitation staining....anywhere on the full meg system...like my one expensive and one free yosh's did and both in less than a years time and under 10,000 miles each.

I liked yosh...as they are synonimous with Suzuki Racing...however...my next system will be Ti and I'd never recommend anyone purchase a system made of anything less than 347SS....not if you intend to keep it a while and want it to stay asthetically pleasing as the 316SS didn't cut it for me....twice in a row at that.

Jap Arata Ti and Ti-Force systems are top shelf systems with automatic weld joints and incorporate tapered headpipes to salvage as much low-mid as possible as does Akro however the Akro's large bore pipe seems heavy breather down low but does yeild stupendouse top-end numbers....I like Brock but don't much care for hindle or the pricing...hindles used to be comparitively cheap systems but Brock seems to have taken them into uncharted territory in both power and price...unfortunately?...the two walk hand in hand....but all four of these particular brands (arata, ti-force, akro and brock/hindle) are located high up on the top shelf....in gold bound glass cases...on red velvet...with matching price tags.
sad.gif


so there ya have it folks...I just talked myself into a Muzzy Full System
laugh.gif
...Ti with a CF Oval Cannister...now...who's got the best price?

Yosh use low grade ss .. Thats a bit dissappointing to hear considering their reputation....

Their customers deserve a bit better than that..

agreed.....but please keep in mind that I'd like to keep that info at a "things you just might like to know" level...and then decide....in an educated fashion.

BTW....yosh did give me several excuses/reasons as to why this happened...

1. Their supplier didn't alloy/mix that particular batch of SS pipe properly...(but if that's so?...they managed to do it twice)

2. 316 bends easier without cracking....(and from what I know it's also easier on the tooling/machines)

3. At first they tried to blame the staining on me for living in florida...(I mentioned that their expressed warranty didn't seem to care where I lived....when I purchased it....but now it's an issue? hmmmmm... )

Like I said...I like yosh due to their support of suzuki racing and they do know their stuff regarding exhaust design but...they could do better by their consumers via higher grade materials.

Well I'll stand up for the bolt on's, I love my Bolt on's because they are a 15minute job, required NO additional tuning, look great, sound great, and are holding up wonderfully. No fuss no muss. No custom maps, no dyno required...

The time and energy spent into properly tuning and installing a full system for 12hp or so is kinda silly in my opinion unless your racing. The weight saved is cool, but really besides being loud, 90% of the time those extra horses are useless. I know it's not the popular mind set, ya know being practical but spending a Grand or two on a bike with 150hp already is mostly a mental/bench racing exercise.
smile.gif


Folks go on and on about lightest weight by 2 lbs (Skip Breakfast). Or 5 extra horsepower (open your throttle all the way)... On and on, I know it's fun to fiddle with the machines, but for the most part garage tuners are only trading Bottom end for Top end, and paying out the ass for the pleasure.

As for the Yoshimura pipes? Dude, the Pipes are fuggin nearly invisible on the Busa, what are ya worried about.
smile.gif
They fit better than most, their canisters are second to none, and they are relatively affordable. Hell get a Ti system and start worrying about how to keep em' silver.
biggrin.gif
But I wouldn't jump all the way oer to Muzzys.... That's like throwing bowtie parts on a Ford.
wow.gif


So I say save your money folks, buy some slip ons, and a track school weekend and really get faster, It's most likely NOT a lack of ponies slowing ya down... I'm not saying you personally Jink, I am saying anyone.

My .02 anyhoo...

+1 .. well said. You've convinced me to go with slip-ons when I'm ready. I agree, doens't seem worth going through the trouble and money for 10-12 ponies.

Impeccable logic, if you don't mind ME saying.
 
bolt-ons, slip-ons,fulls...whatever. Do it for look and sound.

if you have a grand or so too spend and want some real HP buy some cams.

I thought I would chime in here, as my soon to be departed GS1150 is and has sported a Stainless Steel Supertrapp system for the better part of 20 years now. I bought that pipe back in 1985 and I think it looks as cool and unique today as it did back then. Not as in vogue as some of the new stuff but back then it was the cats ass and nobody else had yet jumped on the S/S bandwagon full force. And after 20 years it still cleans up real nice. The new owner picks her up Saturday and I will miss her and the sound of that pipe! I am still looking for the right exhaust for my Busa. I do know that I want it to be as easy to care for and live with as that old Supertrapp.

I think it's pretty impressive that they changed it out for ya really..

the staining (I'm assuming) would have virtually bupkis to do with the performance of the pipe. Most manufactures don't warranty anything for the finish for very long.

anyway.. in real world value... aside from the aesthetics... does the staining have anything to do with anything?

not being a smart ass or whatnot.. just curious..

I wonder what micron uses... the head pipes and mid pipe on mine are pretty much that golden straw color you mentioned.

Yup. Had Supertrapp on my 86 Husqvarna 510 4 stroke. Solid as the rock of Gibraltar, so was the bike. The current owner still has it after 20 years of abuse. Mine had removeable "discs" to compensate for weather and altitude as needed. Great product...made in the USA.
 
HMF high mounts are made from solid billet carbonite so uummmm....that's what i'll buy.

Oh, they work well with a TRE too.

OK seriously, I do like full exhaust but the Busa was built for Duals and that will be the end of that one.

Cheers for the info, I don't have a thermal engineer handy. I have wondered about the staining on my yoshi system and thought I had down something wrong. To be honest, I listened to all the available sound captures and went from there. A couple of extra horsepower wouldn't have changed my mind and I detested the way the factory system sounded. I guess as material costs rise, so will the product until they become unobtainables. I would kill (and you would have too) for some of the gear they run in the superbikes or motogp, who wouldn't? So Jinks, do you have anymore in depth stuff like this, how about another thread on steering dampers? Next time, I might choose real world quality over pretty colours and brand name.
 
I've been to Freddies school in Vegas and Kevins track school at Road Atlanta. My gains amounted to more than any exhaust system, fuel system or new shock/spring system could ever do
