ordered my rumbler
Ordered my rumbler Xpipe today
Are CarSound cats good? How well do they flow compared to no cats at all and what will be the tone difference? I should get some cats but if its gonna rob my performance dramatically then I say to hell with it--- leading me to my next question... Beside O2 simulators, (whats the best sponsor to get these from?) is there anything else i will need to finish my exhaust package? I couldnt think of anything but I just wanted to make sure. Thanks for the help guys.
