I saw a civic hatch with a motorcycle racing slip on muffler. Is there any performance gain and how would that sound? if you think about it , they are staight through and have a 2 1/4 piping so i guess can be less restictive that a stock muffler right. just curious to see waht you guys think. I think it stupid but each there own

 

man i seen it also on my buddy's LS/crx it sounded good it wasn't like a yosh off a r1 it was like a shorty stunt can it really looked good i didn't even noticed what it was looked like a short n1 w/ a 2'outlet as far as gains i don't know???. ......also seen it on a 99 yukon w/duel exhaust lol what a tard sounded like shizzzzz
