deleting cats i'm considering deleting my cats since pa doesn't test emissions in my county. What would be the cheapest way to go through with this? getting a new off road y pipe? or just getting pipes that replace the cats with straight pipes? I also know that i need o2 sims for the second set of o2 sensors. My car is pretty much stock except a slp lid and a Tsp rumbler cat back. Wouldm that make my car louder cause the rumbler isn't loud enough...lol.
deleting the cats will make your car alot louder. im waiting on my o2 sims to come to cut mine off, since i jsut had a true dual setup installed. o and it sounds so nice. just put pipes inplace of the cats you have. thats all i did on my lt1 firebird and it took about an hour.

removing cats on a stock exhaust should be worth around 5-8rwhp.
if i were you i would buy some cheap long tubes, and just have a coustom y pipe made.
and keep your cat-back..... will be loud, but you should pick up around 15-20rwhp!

is there a place that sells test pipes that go where the stock cats go? or should i just go with a new y pipe that doesn't have cats?

SLP (and probably others) sell replacement pipes for the cats. Kinda pricy, though, and for another $100 or so you can get LT headers. Same with the ORY pipes for stock exhaust headers. If you can find a friendly exhaust shop they could take your cats and cut off the flanges and weld up something.

Just gut the Cats and get O2 sims thats what im doing, had SLP LM exhaust and wanted something louder but couldnt afford LT's so I just got some O2 sims and gutted the cats. Just a thought keeps from spending too much before the headers.
