slip-on cans

[texas-buzzard]

Do slip-ons just give you a better sound or dors it improve your performance? Also will they affect the fuel mapping enough to have it re-tuned?

mostly for sound and looks.
some are alot lighter. you should not have to re map but posibaly yopu will need a par removal or marble mod.

Just slip ons are for sound and looks

. And if you buy Yoshi's, then NO mapping is needed (don't know about any others). But it helps alot anyway if you do get a Dyno tune and remap
