Opinions on Alien Head?

[JPunisher]

Do the brocks exhausts include a baffle to reduce noise? If so does it help any?

kinda shaped like an upside down triangle... big eyes...

OH- THAT alien head...

lot of good reviews...

I love mine. With a good tune it adds power. Gotta great sound when you crank it and not to loud just around the hood. As long as you take it easy. I have stainless steel head but recommend the other type. stainless steal is hard to keep polished without showing a lot of scratches. It was the cheapest though.

Remember to get a good tune. Idont know if a pc5 will be needed if you have a g1. but I could be wrong. I had my g1 tuned by ecu and its wonderful.

Does come with a baffle and sounds great,especially when you wind it up.

I have the Short Meg and performance is the same as the Alien Head except the Short Meg's baffle is removable(which is pretty obnoxious on the street,I've tried it)and the Alien Head's is fixed.

A Lot of guys prefer them and use them in a ton of performance builds. Can't go wrong with choosing that pipe unless noise is an issue 4 you and or your neighbors. That pipe is particularly loud so just a heads up that if your looking 4 a more subtle sounding exhaust this ain't it. You might not care but your neighbors might when you come home late @ night on your busa

Good to know. Lots of motorcycles in my area, so a fairly high tolerance for pain. I don't mind loud pipes just to let the blue hairs know I'm around. I just want to know there's a noticeable difference in the performance. I saw a thread about dyno or not to dyno. I figure if I want it truly tuned in; I need to put it on the dyno and do it right. :alien:

I run the short meg, same pipe different can. You can expect 12 - 15 ponies on the pipe alone with the base map. Absolutely find a great tuner and unleash that ECU for that and maybe 5 - 7 more ponies. Suzuki really detuned the gen II s. Make sure he takes care of those secondary flies, zuki made them extremely lazy. It can be fixed.

I live in a very conservative neighborhood, regardless , out of courtesy I keep it below 1500 in the hood and I don't ride at night, but if I came in after 9 PM I would probably idle through. It's not that loud until you get busy with it. I usually hit it hard through 1st gear when I leave the hood. A lot of kids and adults have made positive comments. I've even got a guy with a diesel shop an 1/8 of a mile away that told me he bet I was hitting 120 those runs are usually around noon or just after and if I let the bike warm up I usually see a police cruiser. Only if there's no cars in sight.

Thanks for the info. Is there a big difference in clearance between alienhead and shortmeg? Anyone scratch the pipes of a shortmeg on a knee drag? I am nowhere near this skill level just wondering.

Call Brock Davidson, the Alien head looks like it would have more clearance, but I'll bet if that short meg is scrapping ur sliding

 

[piratediverjefff]

I agree with dad bro,don't think you could scrape either pipe unless you were almost horizontal.

 

[JPunisher]

Can't remember where I read this but I read that the Alien starts off as a Meg but is then compressed into its shape to allow for additional clearance. If they are going through all that trouble, somebody must be scraping. I was planning on emailing them. Not for this question but to see if they have a noise chart (dB) available. I might as well kill two birds with one stone. Thanks.

When sales started dropping, Brock pulled the "Want your HiBoosa to sound like a Harley....." advertising campaign

Sent from my dunce stool

Hmmm. I probably shouldn't look.

If you look, you'll want, just like me. Though I have no need for the extra performance I'd turbo in a heartbeat if I had the budget for it.

Emailed Brock's last night and got a response this morning.

I’m interested in purchasing a Brock’s exhaust for an 08 Suzuki Hayabusa and was hoping you could help me with some questions.

1. What is the difference between the Alien Head and ShortMeg?
2. What is new with version 2 of these exhausts? (Example: ShortMeg 2 vs ShortMeg and Alien Head vs Alien Head 2)
3. What are the dBs for these?
4. How much noise reduction should I expect with the noise reduction plug?
5. I read somewhere that the Alien Head was designed to provide additional clearance. Does this mean that the ShortMeg would scrape against the pavement during an aggressive lean?

Any help with these questions would be greatly appreciated?

1) The Alien Head has the “alien headâ€￾ shape and a permanent baffle. The Short Meg, is round and has a baffle that is removable.
2) The Alien Head 2 and Short Meg 2 have larger flanges and a muffler that is 2.25â€￾ all the way through, where the original Alien Head and Short Meg, have a muffler that starts at 2.25â€￾ and tapers to a 2â€￾ exit.
3) The way the we measure the DBs they are approximately 108 DB at 5000 RPM.
4) Noise Reduction Plug on those pipes with reduce the DB about 2-4.
5) I have never heard of anyone having cornering clearance issues with the Short Meg, but if you are at a road racing style track and you are laying the bike pretty much on its side in the corners, it could be possible to scrape.

I hope this helps, let me know if you have any other questions.

Thanks,
Steve

Some additional questions and response below.

Steve,

Thanks for the help. One last question.

Is there a performance or noise (dB) difference between versions 1&2 (Example: Shortmeg 1 vs Shortmeg 2)?

http://www.brocksperformance.com/images/Busa_AH_2_Pipe_Dyno_Comparison_Zoom.jpg
About 2 hp difference between the 1 and 2 on a stock motor Busa. DB level is very close, the 2 is probably a tiny bit quieter because it has a slightly larger muffler.

Thanks,
Steve

Dayum 2 more RWHP, what a monster pipe, the only pipe that out performs it is a dump
