anyone use the whole HR exhaust? i know people use the Y pipe as an upgrade to their g but do people use the muffler and mid pipe as well? i'm going to get an HR exhaust to toy with to see if the Y sounds any different than my ichiba Y pipe. if it sounds better i'll use it and sell my ichiba. will probably get rid of the rest of the exhaust too after i get under the car and check it all out. there may be a few interesting possibilities there. we'll see.

Everything in the HR exhaust is the same except the Y-pipe. And also, the HR exhaust is different from the 370Z one.

I was using the whole cat back from my buds 07 z ofcourse with a nismo midpipe extender and in my opinion it sounds better. More pronounced and a little louder. But yeah the 370 exhaust runs a whole different for exiting.
