gutting cat converter

hey guys. i got a 2.5 inch exauhst put on my wagon with only one muffler but i want it louder. the guy said extractors wont make it any louder, just smoother or sumthing. but he said he can gut the cat and put a 2.5 inch pipe through it and this will make it louder. is this true? any side effects? this is only costing me $50 aswell so if it will make it louder i think i will get it done. cheers

Re: gutting cat converter

Unless you run straight gas, or have 10,000 at least in your pocket to pay the EPA for this illegal mod, go for it ....... NOT

Straight Gas is fine for this mod as it will pass EPA and is a good idea to keep Mr plod believing your system on visual inspection is legit, if you run un-leaded AT ALL, then expect to get hit with a big fine and not worth it IMO.

Re: gutting cat converter

spend an extra 100 or so and get a decent hi-flo cat ... Gutted cats wouldn't do diddly to the volume of the gas...
It is just a plain bad idea to do that.. They are there for a reason, think of your kids and the enviroment instead of a touch more performance

Re: gutting cat converter

i was just doing it purely for the sound. he said extractors will not make it louder so is there any other way to get more noise? i actualy do only run gas because my fuel pump is broken and im not getting it fixed. will this be a good enuf exuse for the cops? would they actualy check this sorta thing because it will still look normal. anyone done this to their car?

Re: gutting cat converter

i dont have a cat at all... It is dedicated gas and although i would pass emmisions it is still illegal to remove or modify the cat afaik.. Funny thing is my car had passed every DOT inspection it had even wiothout one...
I would still stick to what i said before... I cant see a gutted cat making any difference to the sound of the system at all... Replace it with a hi-flo unit, or extractors.. IMO good headers should make a difference to the volume as the exhuast gas pulses flow more consistently, giving you a better note not withstanding the increase in performance

Ignoring the illegal notion of gutting a cat, whoever said extractors dont make your car louder is, in 99% of cases, full of crappola.
I cant say for everyone but, in every case I've ever come across with car running a stock manifold v's extractors, the extractors have always been louder (all things being equal from the cat back). Not only that, they improve the engine efficiency.

Just get the extractors.......and go somewhere else because the person who told you this is an idiot.
