Congrats on the Nismo exhaust! It's a sweet set up and fits like a glove. As far as I know, Papa D is the only member to implement an X-pipe into the Nismo exhaust. He reported no noticeable gains in power but it did quite and change the tone of the exhaust. Both of which were his goals.Just got the nismo exhaust an curious if anybody has put an x or h pipe into the set up an also wondering if you could do both?
Pros an cons? Thanks in advance on info
