I Installed my headers and o/r prochamber. I got mac pro dumps also but wanted to hook up my catback first to see what it sounded like. I bought the car with muffler cutouts. It sounds awesome with the cutouts, I thought it was going to be annoying loud but it sound pretty good. I was wondering If It is bad to run the car with this combo. Do you guys think I'm losing power?
Im done with my install now and its too load under a load. Im going to put my produmps on. It was fun driving it around with out mufflers, people were like :nonono:.
you might lose some low end torque with out the back pressure of the catback, but the midpipe should have taken care of that enough, so I would say that its not hurting anything, except your ears!
I was kinda thinking the prochamber would help a little on the backpressure also. I wasn't sure. Its just to loud under a load and kinda sounds like crap higher in the rpm's. Its really raspy up high with no mufflers. I like that low growl. Setting there reving it sounds awesome though. Ran a 9.7 in the 1/8th I'm hoping for 9.5 or something close to that now.
