Difference? Yes or No?

[haulbalz]

I always thought that the cobras had 2 1/2 inch midpipe... Well I measured it and it was only 2 1/4.. will going to 2 1/2 make a huge difference for my setup?

i think all aftermarket mid-pipes are 2.5"

are you still running the stocker? switching to an aftermarket piece should yield you nice gains with those mods

I've got the stocker with no cats... still a nice power gain?

Probably a little. Go with an O/R X it sounds great and should be better.

An o/r mid-pipe is proven to add some nice gains. I went from a 15.2 @ 92 mph to a 14.8 @ 95 mph with an o/r h-pipe and pulleys. So it's probably good for at least two tenths. All stock mid-pipes are 2.25" and aftermarkets are 2.5" Good luck

awesome, thanks for the help

With your setup I would do full exhaust(headers back). Your really blocking the air flow though the motor.

Agree with above...if you open up one side or the other, but not both, you still have the restrictions there, although the sound is probably gonna be better.
