Re: muffler delete
I deleted my ATR muffler on my truck after less than a month, too quiet... You will be OK as long as you leave the cat in place. If you opt to delete it, you will need to run an external wastegate to keep the boost spikes in check. Stock turbo plus no cat is a proven recipe for out of control boost in our applications.

Its Very Loud And Makes The Truck Sound Like A Tractor. No Overboosting Issues Here!

Re: muffler delete
yep, spool was loud as hell when I had the stock setup with just the stock open DP with a turndown on it.
Its just about 100x louder now with the 52 and 3" piping
Definately not for those states who have emissions testing. You can hear me coming down the street miles away.

Re: muffler delete
does anyone know where some sound clips are of stock exhaust and no muffler? also what kind of muffler is the stock one. Will replacing it with a straight thru help any?

Re: muffler delete

Re: muffler delete
are you kidding, you cant hear anything?! you sure its a 4.3 turbo and not a CPI?! :rotf:
if you can find one, get a saudi cat. its basically a straightpipe masked as a catalytic. I dont suggest it though unless you have some sort of boost control.

Re: muffler delete
when i first bought my sy back in 94 i only knew it was turbo awd and fast. lol. so i gutted the cat. opps crazy over boost.
i can hear the turbo only if i hit the gas for a sec with the brakes on. other than that nothing.

Re: muffler delete
Right now my truck is mostly stock when I bought it, it had no cat just a down pipe, resonator and a straight pipe. I didn't notice any boost problems but I only ran it w/o the cat just to get it home then I had to get the cat on for emissions. Anyways right now I have a straight pipe ran from the cat back and it i think it sounds alright. I can't hear the turbo spool in the cab either but the ppl I run w/ say they can hear it outside so eh. Oh and I have no muffler just the down pipe, straight pipe and cat its alright for now.

Re: muffler delete
what kind of mufflers are you guys running? Sounds like a straight thru muffler is the way to go over like a 2 or 3 chamber correct? 3" pipe also? What is the stock pipe size?
