If you cut your cat off it will sound like crap!

Ask the TO guys on how loud my car is with a straight pipe...it's loud, too loud for me even. Although it sounds like a race car, it doesn't sound nice.

I took a friend to a shop to have his headers put on PGT. He had the pacesetter headers and they had no flex pipe. He had to move his cat back a few inches. He had said to put in a test pipe instead and I told him not too, it would be too loud. He does it anyway and now he is kicking himself for doing it. Hes now ordering a free flow cat (still will be loud with that) to quiet it down some. You can always add baffles too to reduce noise.

Exactly, I got a silencer coming in this week, but with the B.S. profiling in Toronto will make my car prone to inspections once it's done, so it's no coming back up this way until i put a cat back on, that's forsure.

In Puerto Rico is up to $5,000.00 federal fine and confiscation of vehicle.

What about using a resonator? I bought my performance cat for $75.00 and this is California!
