You want new tips? I can help you out if you want my old ones hahaha, I have 4" magnaflow right now on my stock mufflers but I'm getting new mufflers! lol. I think Envied G has the H pipe.

The "X-pipe" on our sedans suck the big one. 25-30% cross section reduction from the dual pipes out of the cats, then they stay like that for miles then split back to the dual. Looks more like two nasty Y-pipes stuck back to back. I soooo want to remove this without increasing exhaust volume but I just bought wheels so need time to save.

 

ok so what happens when u get a h-pipe with stock mufflers??

louder... faster?
