what exhaust give the best power gains on an ITR?

 

Hytech or SMSP.

 

custom depending on your other mods

 

 

IMO SPOON N1 is the best. They're light, very high flow and bolt right on to your B pipe.

 

How's the Apex'i WS? And the Apex'i N1?

Edit, also, anything on 5zigen?

WS sucks, its not straight through so performance gains are minimal. N1 is great, but it is loud.

EDIT: Damn it CHRIS!!! 5Zigen is great and isnt too loud, but the cat-back apparantly has some bottle-necks at the resonator and cat.

how about mugen ?
is jdm mugen exhuast 2.5 or it's 2.25

 

mugens nice, but the loop part is supposedly made of smaller diameter tubing than the rest of the muffler. However, I'd get it. Mugen sound is GREAT!!! The diameter is approximately 2.38" and supposedly decreases at the loop.

The Border304 speed is the only model I like under 5Zigen's name.

 

Exhaust b-pipe sizing is more important than exhaust brand when it comes to performance.

 

Custom exhaust or MUGEN Twin Loop
