So I was on g35driver and found a interesting post about a guy installing a xpipe to his stock exhaust..... If interested here is the link read on....

Got something done today... - G35Driver

Ps if anyone has done this share your comments seems interesting.... I will probably be doing this in the next week or two!

 

Hm looks interesting.. If you do it let me know if you felt any power difference.

 

saw this as well but as I said in the other post, take a close look at your y pipe. There is a portion which pinches and contricts to a MUCH smaller diameter than even the stock exhaust piping... You will def change sound and add a tiny bit of power, but changing the cats and y pipe would increase the flow more than anything else imho.

 

i am planning to do it!

 

eat I want to get the cats as well but I contacted the vendor that does the resonated ones on the price and he hasnt responded anyone know how much they go for?

 

best price i found was about $62 for the xpipe not bad!

 

Well changing the y pipe is a bit different from this x pipe setup. I heard from a couple of friends that the y pipe didnt really make any noticable power difference.

 

Check with some exhaust shops around you. The place I went to in town had them for $30. They were stamped from Magnaflow too.

 

I've heard the same thing about changing y pipes out. Thats why i did the x pipe. Power wise you can feel some change but its not monumental. Seems like most aftermarket exhaust for our cars either have x/h pipes.
