ccs98gt

i have a 98 gt with minor engine mods, but 2 days ago i put an offroad x pipe and flow through mufflers on it. because of my setup i was wondering if it will hurt my heads or any part of my engine. i mean there is almost no back preasure from the flow throughs.

its fine. if putting aftermarket exhaust on hurt the car...not every1 and their mother would do it lol.

i would assume not... more air out means more air in and would more likely help your engines performance.

agreed. If anything it'll help the car be more effiecient. I have the same setup on my car, and it runs like a top with 83k miles.

if u put an o/r midpipe, it may trigger the CEL and that will hinder the performance of your stang.

If theres too little backpressure you can burn up your valves...But you have to have like 0 backpressure to do that....too much back pressure and youll burn up your transmission...but i dont think anyone on this forum has to worry about too much back pressure, lol.

your fine, only running open headers will hurt the engine.
