no....sometimes the cat can crack or spill debris in your exhaust, thus resulting in ur turbo damaged and makes a nice jingle bells noise

do you think itll be fine for a little bit?i just bought the car and im a little tight on money to pay for some welding. also will the check engine light come on? if so what do i do to turn tha off? i know on my 04 mustang we either got a tune or a "mils" that tricked the computer in telling it, it still had cats.

If your SLP cats are like my DynaTech ones, then they should not be a prob. They are not ceramic inside, so nothing to break apart and go down the exhaust stream. They are usually platinum/gold coated stainless mesh. I've had mine on for 3 years. I would not run the stock ceramic filled cats.

Just my $0.02

FWIW, when I broke a ringland on my stock shortblock, my cats SAVED my turbo... I took off the midpipes and turned them upside down and alum chunks fell out... those would have went through the turbo if the cats didnt stop them.

Yes, but you can acquire or make a simulator.

You can either get a sim for the rear O2's, or simply "remove" them from the fault codes using HP Tuners, EFI-Live, etc.
