This is a discussion on No cats that bad? within the Exhaust forums, part of the Performance category; Well I went to the local muffler shop today and told them I want true duals x pipe straight pipes ...
Well I went to the local muffler shop today and told them I want true duals x pipe straight pipes and the guy was ok with everything and then I told him I wanted to cats cut off and he looked at me like I was from outer space. He then explains how "bad" it is to cut off the cats like the truck would explode if I did. So I was like ok well thats great I know plenty of people who have done it and had no problems. Then he starts like asking me who my parent6s are and what kind of neighborhood I live in like I was white trash because I want a loud truck.
So anyway he barely even agreed that he would do it but I have to bring my dad up there and let the mechanic explain the whole process of going catless. Soooo yeah is cutting your cats off THAT bad?

think duals would be questionable...your gona lose torque lm bettin...bin der done dat...
personaly if i were to go that route would go with single 3in to muffler then duals out
then theres your smog testin if you have it in your area...will fail without cats...anyway..food for thought...my duals cost me 1k...it then cost me 600 to get 3in put in...

You're asking an exhaust guy to break the law and he is probably a bit uneasy about it. He's no doubt going to explain that to your father and put your father in a tough position to make the decision on whether or not to allow the cats to come off. You're engine won't be harmed, but the low rpm response and power will suffer.

Cats off will sound louder.

Cats off will be louder, but if you leave them on, It will sound better and still be freakin loud. Just do true dual straights w/xpipe from the cats back and see how you like it.
Alright I'll see if I like it or not.

Cats on!
Reason the exhaust shop looked at you like from outer space is it's a 2500.00 fine (if not more) to do what you asked. And technically by law he can't do it.
However if you were just dead set on having no cats do it yourself. Because If you go into a muffler shop and it's not there "they can't get in trouble" but only recommend you put cats on.
I own a 96 that didn't come with cats...thank you to prev owner... I did cut mine off my old 97 after second set of cats went bad...I wasn't spending more money on high flow cats that were gonna fail.
Now I'm not telling you to break federal law by removing cats, but the age old excuse "it was like that when i bought it" sure does work.![]()
When I was stationed at Ft. Drum, NY, I had problems with an exhaust trying to get them to replace a cat on my old toyota...and it had one on it.

oh really? if my dad tried to make the decision to leave the cats on any of my trucks, i'd tell him to go pound sand and buy his own truck to put cats on.Originally Posted by Tweaks

If you had 2 sets of cats fail you have another problem before the cats. Cats don't just fail.Originally Posted by JCribb

Both of my trucks I have owned have no cats, but truthfully I would rather run cats. My first truck I welding in straight pipe because the cat was 16 years old and it made the truck sound so so awesome. On my 02 model truck I went with the OBX system that features resonator that look like cats because the same setup with cats cost $600 extra.
You will not lose power without cats if the rest of your exhaust is the right size. at most you will lose about 5hp on the same setup when you add cats.
