So I have TopSpeed on my 08 sedan and love the sound... yea the tips are slightly jagged but the sound more than makes up for it. So my question is WILL it sound or perform noticably better/deeper/etc with say a Megan Y pipe? Or will there be little to no difference?

 

you mean X pipe right lol

 

no I mean Y pipe

 

I've done a bit of research on this and from all I've gathered the Y-pipe seems to have the smallest effect on the overall exhaust performance/sound. Much better to invest that money in HFCs or test pipes.

 

Thanks. I live in CA and really don't want to risk a $10k ticket with those that's why I took off the test pipes... But I found a local used one for cheap so I'll try it anyways and will have to let you know.

 

I was wondering the same thing. I want to get the y-pipe and probably ART pipes or HFC

 

Post up a review once it's installed!

 

Any update? I didn't see a Y-Pipe for our cars on Megan's website. Did you pick one up for a G37x?

 

Look into getting a motordyne xyz straight pipe I got one on my 08 sedan with greddy spec axle back exhaust sounds good

 

So I had it on for a little while now. It made the exhaust sound deeper. I feel like it made a good sound better.
