iv got a 2001 1500 with 5.9 v8 and right now i got it straight from the cat back with 3in pipe from a 3500 but its not loud at all...idk if i can gut my cat and keep my check engine light off? or if there somthing else i can do to make it loud? idk but any advice is appreciated

thanks,
cody

 

I'm not sure about the cat but i do know a high-flow cat will make it louder. Does your truck have a muffler on it or is it straight piped?

 

it is straight piped from the cat back its a stock cat with 3in pipe all the way to my tips.

 

you can gut the cat... And if you get a code you buy a slim to make the computer think it not guted thefastman.com sells them

Also you have a01 you cut of the cat and just put a pisice of pipe were the cat was thats what I would do if I did want the cat

 

ok well i dont even know how to gut my cat unless i take it to local muffler place and pay them to do it...or is there somthing within a reasonable price range you reccomend for best sound?

 

my truck is straight piped from cat back and its really loud. i have a sliding rear window so i can hear it alot better so that may be why u dont think its loud. have someone else drive it down the road and listen to it. u might change ur mind then

 

I doubt you want to do that...its illegal in most states I believe since it renders the cat usless ands increases the pollutants it dumps into the air...(whole reason for it in the first place)
Your SMARTEST option would be to get a high flow cat and that way everything still works right and will pass emissions if ever tested....and its much louder while still retaining some of the needed backpressure for low end power.
if you remove the cat and get pulled over for a loud exhaust you may regret it.

 

I gutted my CAT approx $50 at the muffler shop. I put in an o2 sim and had nothin but grief, took out my tranny and PCM. Wouldn't advise the o2 sim. I welded in an o2 threaded nut into my pipe and reinstalled the 02 sensor and havent got a code yet. I run a flowmaster 40 series with 2.5'' exhaust. Sounds real good but not crazy loud when you are driving down the highway for long periods of time.

 

check out youtube for vids and see what sounds you like there so many exhaust done diffrent ways

 

ok and also iv been wanting to know what would be the best thing to get performance wise that isnt to terribly expensive but worth it...iv looked at programmers, mild cams, superchargers and leanin more towards a supercharger.
