i use it on Borla. As far as test pipe, expensive doesn't mean anything. I bought the HFC (random Technology) and the sound isn't that great compare to this one.

 

I'll be sure to make a video of how it sounds inside/outside the car with my handycam and update this thread so people will know for future reference. I am trying to get my BFG's right now, and after I find those with a deal Ill go test pipe hunting, thanks for the help guys if the ones bubble posted are gone off ebay Ill go with an APS or maybe megan.

 

These were my labrees before I sold them:




You can buy them HERE

The APS test pipes can be seen HERE
Nice thing about the APS is that they come with all necessary hardware and bolt up like the stock cats do - they have pretapped studs and the hardware is very good. Helix for example only comes with half the hardware.

You can get APS test pipes from GRD for about 200 bucks. Call them @ 630-369-2800. Tell them Aaron Z referred you
