hey,
i am looking for a dual exhaust and was talking to a guy who said that if i put a H pipe on my 05 V6 then it will make me lose HP, or if it does not lose HP he said it will at least be a little slower off the start then a Y pipe. i currentley have a trufiber ram air hood and i was planning on getting a C&L air intake, 70mm BBK throttle body and headers. will these be enough for me to be able to maintain the HP or should i stick to the Y pipe. he said that i should get the y pipe as well because nobody will every find out its a y pipe unless they get under my car. so whats ur input guys?

 

S197s gain just as much from a single cat back as duals, so id look at an MRT catback

 

actually you'll gain HP, but you'll lose back pressure which is torque. I believe if you go with 2.5" piping you'll be ok.

 

I say it depends on sound that you're looking for. I don't think the Y is as loud as the X or the H. They're about the same hp wise, but I think the dual exhaust always looks better than single

 

i always get rid of the y and completely go true duel w/ no mid pipe or even with the x or h. just really depends on your sound preference. i kno that no mid pipe can be slightly louder x raspy, h deeper- my preference. And you wont lose any hp as vovo said you will lose back pressure but keep w/ your stock pipes and should be even
