dont know if many of you guys have learned this by now. But i have been told that when you do forced induction you need to take your catalytic conver off and straight pipe..i blew the filter/porcelan in mine sideways and my car was running horribly cause the exahust was basically jammed inside, now that its straight piped the thing rides like a bat out of hell.....INFORMATION REGARDING THE REMOVAL OF CATALYTIC CONVERTOR GIVEN TO ME BY KRC PERFORMANCE..A SHOP THAT IS WELL KNOWN IN FLORIDA FOR ITS SUPERCHARGING WORK. it just makes sense,,think about it. LET ME KNOW IF YOU HAVE ANY QUESTIONS OR COMMENTS.

yup..thats the reason i had mine hollowed & sleeved when i had a blower..worked a LOT better

Well great, I just had a freeflow cat welded on. Kinda stuck with it now. I would have to get a fly by night muffler shop, or know someone who welds to put a straight pipe in. Beings its a 20,000 fine or something like that. My sc is doing better with the headers tho

[PonyRunner96]

believe me when i say it was the best 50 bucks i ever spent.

as long as the tubing is big enough, you should be fine. 3" or 3.5" exhaust and cat. should be ok for 6-9 psi from the powerdyne's. The larger the area, the lower the velocity of the exhaust.

[1DangerousV6]

yeah the stock one sucked..but a 3 inch or larger high flow one should be ok

Can't do that in Calif. Mine has to stay legal and be able to pass smog.

I never had that happen to me. Weird.

[PonyRunner96]

ya i hear what you guys are saying, sux for you in Cali. brother, damn you pollution control activists. but the way i see it, just having a Catalytic Convertor being hi-flow or stock still causes some restriction. straight pipe is the way to go (with forced induction that is), you wanna keep your exhasut system as free flowing as possible. just telling you my opinion, i can see what mighty thor, were your coming from, all im saying if you took it off you would notice a gain in power and a throatier exhaust note.

High Flow cats are just as effective, and much cleaner. You need to have a little backpressure in there to make power. Not sure which sounds better, but I can say a hollowed cat sounds like a raspy tin can ready to explode. Maybe the straight pipe sounds decent, though. Just fyi, I'd be careful about posting the name of the place that hollowed your cat. It's a $10,000 federal fine and if the wrong person sees this, you're going to screw them and yourself. Also, not to be a nudge, but you need to show your email address.

ya im working on my email, but i work for the state and they would prolly give me crap over misuse of it other then work---for the record krc is a supercharging performance shop all they gave me was ADVISE NO WORK DONE...they dont touch mufflers/exhaust...another shop did so. i understand what ur saying bout the whole little backpressure i guess it just comes down to personal opinion, on top end in my opinion the higher flow possible works best, but thats my opinion im not forcing anyone to do what ive done. thanx guys.

Backpressure, you dont need much backpressure with forced induction. ;)
