Straight pipe's for 2nd cats or resonators??
Hey guys just wAnted to know straight pipes instead of the 2nd cats or resonators!?? And Which gives me more gains taking out resonators with straight pipes or taking out 2nd cats with straight pipes, plus I have the k2 so want the most of it!! Thanks...

You will definitely see more gain by losing the secondary cat. I do not suggest removing the resonator because the stock resonator has the crossover pipe integrated into it. That crossover balances the two banks. Just my suggestion.

If you have K2, why not take off both cats and leave in the resonator? This is essentially what most folks would have running the LT headers right? I assume with the K2 programming you'll pass emissions tests either way...and without the program, you'd fail either way. Why not go for the extra horsepower?

I've been told if I'm in a state where the emissions test is the OBDII test, passing emissions should be no problem with a Kleeman tune and cat delete. The secondary O2 sensors need to be plugged in for the ECU to see a signal, but it won't matter what the signal reads.

Thanx for ur suggestion man I know that's the best way for free flowing the exhaust and givin more power so I guess I'll do that!! so what bout sound how is Gina be really loud or slightly louder!??
