Gutting the cat can (not necessarily "will") trigger a code for the REAR O2 sensor. (post cat.) That's just the pcm whining about cat efficiency, and does not affect how the truck runs. The non-fouler trick on that sensor solves the problem.

 

i have never had a cel for no cats and its been like four months with just havin the pipe unstead of a cat

 

wow, sounds good. i heard a 10 series the other day, although it was a sound clip. you just confirmed what im going to be doing with mine in the next couple weeks! i have the summit racing 3" i/o dual exhaust and the muffler is way too quiet for my liking...

 

Yeah I only took it to 4500 real fast. Its plenty loud. Wish Summit would have had 3 inch pipe instead of 2.5. Ive had the flowmaster super 44 on it didnt like it, flowmaster delta 40 didnt like it, so I went with the one that is for OFF ROAD USE ONLY! lol

 

my summit exhaust is 3" from the cat back. here in NH(or at least where i go anyways) for inspection all you need is a muffler with some sort of baffle in it. and as long as it looks like a muffler it will pass inspection! i think im gonna gut my cat when i buy the muffler and install the non fouler.

i had a glasspack pass inspection before so i know anything i put on my truck it will pass.

 

i was expecting more, need examples? hold on a min........cant upload my vid i just did but here's one to tie you over http://www.youtube.com/watch?v=TYmss_2m6Ug

 

lol I dont run the **** out of my truck. No need to, doesnt have 1100 hp or else it would probably sound like that too. Good chance that guys is going to either cause a wreck or f**k something up nicely.

 

Thats why your state senator wants to ban any modification to exhaust systems. Thanks for ****ing it up for the rest of us. That crap belongs on the track.

 

No kidding right! IDIOTS

 

Most states have laws about how loud an exhaust system can be. Rather than banning it and/or making new laws, they just need to make sure the current ones are getting enforced. My state has a law about how loud an exhaust can be, but the cops never enforce it.
