Here is my 3" exhaust with Dynomax bullet muffler as a resonator, 3" from Custom tubes, and Flowtech Warlock muffler.

Cavy Exhaust

What do you need 3" exhaust for?

yea 3" exhaust hurts flow big time, disrupts scavenging and will make your car slo.. I mean..

wait, I have 3" too

I picked 3" because I plan on moving a loooot of air through my motor. My plans are a fully ported 086 head, HO cams, 75mm throttle body, large tube header, 2.3 pump swap to get rid of ballance shafts for higher reving, and a few other things along with a new bottom end. To be honest when I get tired of that and I most likley will Im almost positive that it will see boost anyways. Why do the exhaust more then once? Tthose are my reasons for the 3".

Besides whats all this 3" hurts you talk anyways....The Skwirl is the fastest N/A eco on the org and that car has 3"....I definitely didnt loose any power with my motor and all I have is HO intake, 58mm throttle body, and 2.2 coil conversion.
