Default Where did you go to get your cats off?

I went to an exhaust place and they said they wouldn't take the cats off because it's illegal. How did everyone get theres off and how much was it to do. Would it make my car sound choppyer?

It's a big fine for the shop if they remove the cats and get caught, however what you do in the privacy of your own garage is your business

In other words, unless you are all out track only, don't remove the cats, the performasnce benefit in very minor, and will cause emissions failure unless tuned out.

yeah most places are sacred to do it now, i have a good freind who owns an exhaust shop so he did it for me.

your best bet is to get a set of longtubes and an ORY and do it yourself

and by choppier, i think that you are thinking of hte effects of a cam. the headers/cat deletes will make it louder, but youll have to get a camshaft swap package to get it lopey. your on the right track now though. you need headers before you get a cam anyway.

and if you have to ask what cats look like, get someone else to swap the cam,

yea man gutting them will just make it run rich and ruin the emissions, just get some headers with a ORY emissions delete and be done wih it. o by the way, get it tuned too. it will be as loud as u can stand with a good exuast. (SLP,Borla,Dynamax,etc...)

If you want to get rid of them it would be best to just install headers and an ORY pipe. You'll also have to get a Mail order tune to remove the rear O2 sensors or install rear O2 sims (which sometimes don't work).

Not that you haven't though of this, but if your state has annual inspections or emissions testing, you'll either have to keep the car legal or swap it back at the time of inspection. IMHO it's a big hastle for the maybe 10hp your gonna get.

A little new here huh? It's alright everyone has a start. A cam will run you up in the 1,000s range when you get everything and instalation. Basicly your changing the way the motor runs, there are some variables that it adjusts but I'm not sure you want that much detail. Do some reaserch you will get it.

... and there are different cams whether your car is a Daily Driver or a Strip/race car. Also before you get a cam there are a number of things that you need first..exhaust/headers/ yada yada yada...

Bassani sells an off road y-pipe that will bolt up to the factory manifolds.
Took me a few hours, had to soak the bolts to get them loose, test fitted the pipes then clamped them down. Been ruuning it for a little over a year and a half, no real issues. I choose this route for a cheap fix over LT's, but I am in the market to some now and will be ditching my currnet set up soon.
