does anyone know where they sell a Cat-Back that is around the 200-400's thats would be perfect for tha S5 NA ???

( 2.5" is good for N/A ryt?)
I was thinking of getting the corksport one but its a 80mm ...will that be too big for my N/A?? will i lose power??

Thanks!!!!!

 

Even though I reccomend the Racing beat setup, Mazdatrix sells a dynomax setup for $421. IMO I think that 80mm would be a bit big for a strait back system, but since its only cat back I wouldn't worry about it too much since you have your cats as your road blocks.

Edit: I forgot the link... http://www.mazdatrix.com/e86-92.htm

 

will i lose any power though if i get tha 80mm one?? will i gain any power???

 

you'll gain power through exhaust mods when you remove your catalytic converters
