This is a bad option, I quickly broke. If we do not boost, it is better to leave the stock.
I have lost 4 h.p. after a set the Top Speed header.

This might be a silly question, but what is the difference exactly between a header and a test pipe? They seem to be thrown around in the same context so I really can't tell. I know what a header is, but the test pipe I'm unsure of. Also, when you remove the cat does it affect your computer at all? Any lights pop up or anything? Thanks for the help.

I've tried both the megan and topspeed headers. You definitely loose low end power but you seem to get more on the top end. Overall it makes the car sounds raspy and way to loud. Plus each header has annoying metallic pingy sound when you press the throttle. The headaches weren't worth it, plus my topseed header weld ended up cracking so I was leaking exhaust into the engine bay. I threw back the stock cat back on and the car sounds more mellow and refined. I'd be interested in a highflow cat, the magnaflow one is very expensive though.

has anyone done a custom header/test-pipe? that would bolt on to stock exhaust? i guess just basically take out the cat and put regular pipe in there is what im looking to do. everything else is stock, got a short ram intake and a custom axle back exhaust.
