I have Flowmaster American thunder CB and high flow cats.

If I want to remove the cats I just go strait pipe from heAders to beginning of Flowmaster?

Looking for a little more flow and tiny power increase

TIA

1) Wrong section - try posting here: http://www.camaro5.com/forums/forumdisplay.php?f=11

2) Eliminating the high flow cats won't change the flow or add any power. Any changes will be minimal (1-2 hp), especially with your mods and current power level.

Okay that's what I thought as well.. Someone I chatted with last night from a sponsored vendor said differently..

Without the cats, the system is labeled as an "off road" system since the car won't likely pass emissions in most states or metro areas.

It's funny because the off road system are just straight pipes and are typically cheaper than the high-flow cats. Once you get into the more serious racing builds, then eliminating the cats have a bit more of a boost, but even then it's not much.
