The thing is, the stock exhaust flows very well in stock form. Unless you have full bolt ons (such as long tube headers and Stillen G3 intake), then you don't really need to change the rest of the exhaust. If anything, the stock y-pipe might be a little restrictive and that's where most of the gains are made when upgrading the cat-back, and it's not by much anyway.

 

not true, my headers fit in with no problem

 

True, plenty of aftermarket headers fit just fine. But did you have to bump a 7 month old thread to say that?

 

was lookin on my ipad, didnt notice it was a 7 month old thread,

 

^ which headers would those be?

 

The GT spec bar looks like a great addition to the engine bay on top of the performance gains. Does anybody know if there are sway bars for the X models available anywhere? Sorry I know this thread is Old As ***.

 

^ you can upgrade to an S model sway bar for some benefit and Hotchkis would be a step above that.

 

Well after another depressing search, I still couldn't find the sway bars for the 07 G35X. Found em for the 08-10 but nothing for the 07...... shiit!

 

If you have a second gen, then they're all the same.
