HIgh Flow Cat?

[magic1872]

What kind of results would I see if I was to slap a High Flow Cat on my 99 Bird with the mods I have?

Where would one get a high flow cat?

Thanks

Well, the 3" Catco from www.Summitracing.com is like $49 bucks. I would only do it if your entire intermediate pipe is 3"

what if its not could i have a muffler shop put a 3" from the high flow cat to my flowmaster because it already has 3" inlets but they put extra pipe on there so it would fit my car

is the part number for a 99 firebird CTO-6007?

all 98+ cars have high-flow cat's on them, it is just the size difference between 2.25" and 3" that makes a big difference in backpressure. only get a bigger cat if you already have or will be puting on a cat-back exhaust at the same time.

what does the cat back consist of, I already have a flowmaster 80 muffler, what else do i need if i get the 3" high flow cat
