Pros and cons? with will better perform? i have the hallowed out cat right now, and its doing pretty good. but i can't compare to the high flow cat cause i dont have one. wanna see if its worth getting. or is just a plain straight pipe evern better then hallowed cat?

not a bad problem

with a hollowed cat or a test pipe you won't pass emissions and you're ****ing up the air. I have a carsound cat and just went to get my car voluntarily tested. 45mins of cruising around and $20 later I passed...

High flow cat are not worth it. Get a test pipe or stick with OEM cat. As for the flame, something is wrong with your car. Unless you have a turbo, SC or nitrous.

don't hollow your cat, it's there for a reason man. It's bad enough we have a president that sponsors an increase in gas guzzling big rigs with bigger engines and higher fuel consumption that burn more oil and are bad for the environment, but you are taking a car that was otherwise mild on the atmosphere and making it pollute more, and all for a measily 1-2 hp?

Hollowing the cat wont give you no gains, Ive even heard it could kill hp for the fact that it doesnt flow through smoothly. Instead it bounces around in the before exiting. Get a straight pipe/test pipe.

Hollowed Cat = Service Engine Light

High Flow Cat = 1.5 Horsepower gain

...it was my biggest waste of mod money.

i hollowed out the 2 precats on my y pipe, didnt see much of a difference, when i get a budget, maybe i will see an improvement...as for the CEL, in over a year with a straight pipe, no CEL, if that was true, ALOT of people on the org would have a CEL

Ya but its holoween this week Ben.

BTW I do run a straight pipe, I think it helps but I don't have any proof. Just that it didn't slow me down any.
