I was wonder if I would gain much from taking out the huge resonater from my cat back? I already have a DP and works high flow cat. I know it would make a bit louder but would it be worth it?

 

Probably not.

 

Cool, I will leave it then

 

i took mine out, i felt no performance gain. It did make it alot louder.

i did take out the restriction in the muffler and that i did feel in the butt dyno it pulls much better up top, but my car is also highly modified.

 

unlikely youll see or feel any gains
