Turbo car. Cat or no cat.
-
In my personal experience, I like my car alot better with a cat on. I had a small round magnaflow high flow cat put on, and it made my car quite a bit quieter, especially at idle. Also it stinks alot less at stoplights, and I think I got a little low end back (lost some top end, but I don't really use the top end that much)
A cat may affect horsepower a bit, but not much, and unless you are squeezing every last bit out of the car already, you could get that back somewhere else. I think for me, the cat was a great decision and i'm very happy with it. YMMV -
depending on application you WILL NOT lose much power at all if you have a GOOD converter. I have made 600 plus to the wheels w/ them and alot of cars sound better with them in place. People that pick up horsepower w/ no converter is generally due to the cats being plugged. Good converters on a supercharged car will INCREASE the HP. I would advise him to leave the converter alone.

I grew up around the smell of unburnt gas so it's no cats for me. I love it. I said I love it.

Lose the cat., put in a test pipe. Chances are you'll melt the catalyst and end up with a plugged exhaust, if you're looking at a bigger turbo and most likely fueling adjustments.

press bent looks like a cambels soup can when its bent, all ripply and shit, mandrel looks like u would think a pipe bend should look, clean and somewhat uniform.
Yeah, it was very nicely done. It was NOT pressbent then. He said it was ~$200 less than he got quoted at SLS, but he got a discount. -

Well with an in house mandrel bender, you can move stuff quicker. But i guarentee that Nicks welds are better than the poop they do at exhaust pros. Spanish-Rice shoul dpost up a pic of his sweet downpipe they made him...
I wouldn't doubt it. He got what he paid for, but it was what he wanted.
