I love mine the way it is right now. But its just stock manifolds and cats with an SLP Loudmouth 1 resonator dumped.

When I eventually get some longtubes and ORY, I am wanting to go with a full 3" single exhaust with a 5x8x6" oval body Magnaflow race muffler and either dump it or side exit exhaust.

 

i ordered a magnaflow 6"round 6" long 3"inlet/3"outlet, should be getting tomorrow, i hope it sounds good.....

 

race series?

 

yup!

it will probably be as loud as my slp loudmouth resonator but i really want to give it a try...

 

8.1L -> StainlessWorks Longtubes -> Magnaflow Ultra high Flow CATs -> 22" Magnaflow dual 3" in/out muffler -> true duals out the passenger side

i love my magnaflow, ive had it on the GTO and my new truck and will never buy a diff brand of mufflers

 

I've said it before, your truck sounds awesome man

 

Im very interested to see your results. Any chance of a good sound clip once you get it in? Right now I'm not running any muffler or anything...took the catback off. It's loud but sounds like smashed ******* I took it off thinking it may get me a little at the track.

 

I like the way my truck sounds but i don't think you would get away with it south of the 49th for Starters i have a very mild cam probably a notch or 2 above stock
Edelbrock Headers into 2 1/2 ince pipe off the collector cats are deleted goes into dual resonators then into a dual in dual out magnaflow then the usual 3 1/2 tips one out each corner

 

where have you ever heard a smashed *******?

interesting...lol

I will say the 4" in/out dynomax race muffler (not bullet) sounds like sex all over the rpm band.
