Catback exhaust vs H-Pipe w/muffler deletes
So I have a 2006 GT,I currently have a cold air intake from K&N which requires no tune and straight pipes. Everything else is stock,meaning the H-Pipe and cats.
My question is : How much of a difference will it make in terms of sound and power if I do a cat back system with 2 individual pipes from each cat right to the back?? I guess basically not having an H or X Pipe,right? My set up now makes good sound. I'm just curious to see if I can make it better without having to go the expensive route by doing headers and a new mid pipe and a tune etc.
