The apexi WS catback is a very mild catback and I can guess that it will provide little gains on the ITR. Will a 2.5" b-pipe with the stock muff actually perform better than an aftermarket catback? Thanks.

I think the stock muffler would be the bottle neck. Although, if you have your R nicely moded, I'd go 2.5" all the way!

Type One b-pipe
Type One b-pipe + Type one muffler

 

The Type-one axle looks pretty good but loud. I'm looking for a quiet setup and the Mugen is REALLy nice but just way too much. Anyone have a used one for sale?

 

We will know just how loud the Type Ones are this week. I am getting my order in. I will post updates once I do. Then again, after hearing the Buddy Club Spec II that we have sold to a few folks, nothing is LOUD anymore !!!!!!!!!!!!

 

DC Sports axle is very quiet but, it is 2.25"

 

how bout getting a 5zigen fireball catback?

 

Nice try.

 

Does anyone know how big the Apexi WS piping is? Is it 60mm like most japanese companies?

I was thinking about getting this catback to complement the JDM ITR 4-1 and Carsound cat im putting in. I currently have the 5Zigen Fireball axleback.

Is it worth the $400 to upgrade? Or have i already eliminated the biggest bottleneck by getting the axleback? I have a feeling the 5Zigen muffler flows better than the WS does, negating the effect the apex'i b-pipe would have....

If anyone has any opinion on this lemme know. thanks--

 

how much is the Type One B-pipe? I need a B-pipe that is 2.5 inch

 

I think the WS piping is 60mm or 2.25. The Type-one b-pipe runs about 350-375.
