Hey guy,

I'm new to the Form and i got a question it my sound stupid but i wanna to make sure. OK i got a 99jdm ITR motor on my USDM 2001 ITR and i have JDM 4-1 Header but i don't have the catalytic converter and Muffler With B Pipe. I wanted to buy or looking for the JDM catalytic converter Muffler With B Pipe , will the jdm be bolt on or is the JDM shorter or longer. I wanted to keep it stock that's why im planing on get the JDM ....any ideas would be helpful thank you...

 

Yes it will bolt in. The jdm b-pipe is longer due to the shorter cat.

 

sounds similar to my setup. since you are using the jdm 4-1, you need the jdm length cat + jdm b pipe, the mufflers are the same usdm or jdm. it is a bolt on affair

 

so as long as i have the JDM Cat. Converter Muffler With B Pipe?...

thanks for the respond

 

i wanted to use everything jdm since the pipe size are different from the USDM ITR

 

I believe the piping is the same diameter as the USDM exhaust.

 

so your saying all i need just JDM 4-1 header, Cat converter, and B-Pipe and use my USDM Muffler ?

 

yep

 

thanks
