Cats or no cats that is the question

I have a 95 gt as you all know.
I got my flowmasters in today and i was wondering weather i should cut the cats and run my flowmasters from there or leave the cats.

dont forget the MIL's too, personally i say X-pipe w/spintchs that combo truly sounds badass. Personally of every combo I've heard it allways sounds better W/X-pipe. I honestly wouldnt get just an H-pipe if i was gonna go that route i would go prochamber

prochamber+flows= :worship:

I wouldn't go dumps though, yeah it'll sound like a monster with the right cam, right compression, and right heads... but im telling you from experience, the loud gets old fast, and every cop in town'll be on your heals with dumps, they know that sound well, I got pulled over 3 times with the dumps, none since I went back to cat back

California does not have any special parts? They use converters just like everyone else they are not made of gold.

Yes .50 cents to a 1.00 depending on how long you use it.

Re: Cats or no cats that is the question

I have a 96 gt. I bought the car with no cats and it had MIL Eliminators on it and they didnt work at all so I put the cats back on and went with 2 single chamber flowmaster. Sounds really good and no problems with emissions now.

Its a federal law! It's ILLEGAL EVERYWHERE! They just dont do testing where you live, They dont test in my area either! If you were to bring you car into a repair shop, by law they either 1) dont work on it at all or 2) dont let it leave until all emissions are met! And yeah you CAN loose hp by removing your cats!
