Hey all, i just need some 2.5 inch piping and was wondering, all those in the socal area how much you want for just the stock, ITR B-pipe? I posted this question a while ago, but i didnt even have enough $$$ for gas at the time. I'm hoping someone local (949) area has one, or someone going to the NW Pizza meet, i'd assume shipping charges would kill....
thanks, -aaron

 

You say you need some 2.5" tubing but you ask for a ITR exhaust. The stock ITR is 2.25".

 

DAVE!!!!
I was going to give you a call or email pretty soon. My proposed setup, is a JDM ITR Header, going to one of your 2.5 inch carsound cats, an ITR B-Pipe and out to a Mugen Twin Loop. Am I mistaken, i thought the stock B-pipe from an ITR was 2.5, ( I have a 99 SI ) which i thought was 2.25......

 

Stock ITR B-Pipe = 2.25"

 

doh
ok, new plan: (ask dave)
hey dave, any suggestions?

 

yes, the restricting ID is ~2.25"

 

No, the restricting inner diameter is more like 1 7/8".
The OD for the largest sections of the tubing is the above stated 2.25".

 

Yeh, the ITR is 2.25"OD at it's largest sections but there are a few bottlenecks in it, the worst being at the B pipe flange. I believe you stock Si exhaust is around 2" or 50mm. The Mugen TL for the ITR is about 60mm tubing but I believe the TL for the Si is slightly smaller but you should verify that. Since you talking about the TL I'll assume that a quiet exhaust is what you are looking for???

 

Hell yes! So what would you reccomend for the B-Pipe?
Regardless of what B-pipe i get, i should still get the twin-loop designed for the coupe right?

 

Some interesting facts you should know

stock ITR b-pipe is 57 mm
aftermarket JDM b-pipes are 60 mm (kakimoto has some extremely large sizes)
