Just installed my GT Spec 2 headers w/ uppipe last week with no leaks. Engine pulls much better now. I am thinking of purchasing a DP, HF cat and midpipe by Turbo XS and keep my OEM muffler. Anyone here running with this set up? Or any thoughts?

 

this is kinda ot, but how much louder is your car with the headers and the upipe ?
