Which dp you guys prefer for me with my stock exhaust? I want to get the most power out of my stock exhaust. Should i get a test pipe too? I need a setup that will fit my stock exhaust. thank you.

 

I have an VIII, but I love my new DC Sports downpipe. My car has ACD and the fit is perfect. No rattling whatsoever. I am pretty sure it'll fit the IX just like a glove too. It eliminates the catalytic convertor. So, no need to purchase a cat delete pipe.

 

I'm using helix products for my exhaust becuase they should preform well up to the horsepower levels I dream of obtaining in the distant future, max 500bhp.

I found when I replaced the cat back, ie the rear section, I seemed to gain power. The downpipe alone didn't appear to make any difference without the catback. I'm keeping the cat because I live in California, at current its replaced with a simple ultimate racing cat.

 

i have TurboXS working great since 2004. i used my 8 now its on my 9. no hitting or touching anywhere. great unit. 3" though and doesn't eliminate the factory cat.

 

+1 on the DC Sports with integrated testpipe...no rattles either
