New To Forum, Need Help Choosing Exhaust.

[Cold Air Inductions]

Hey guys, I am new to the forum and recently purchased a 2001 Sierra 2500HD 4X4 with the 6.0L engine. I removed the Cats, and am looking for an exhaust (muffler and exit pipe with tip) and will be getting a tune and CAI soon after. I would like to go with either a single or dual exit off of one side of the truck behind the rear tire. My biggest concern is that I want something that will not be to loud or obnoxious, especially while cruising the highway, but will give the truck a little better growl and sound when punched. Please let me know what you have and what works well with this kind of set-up, sound clips would be extremely helpful. Please remember that I do not want a super loud one, that phase was 10 years ago for me LOL. Thank a lot!

why did you take the cats off if you dont want it to be loud?should of left the cats on.besides losing power mpg taking off the cats doesnt do anything.With a flowmaster 40 it might to loud might have to look at maganflow or corsa to obsurb the unwanted popping and etc.

I have not noticed the removal of the cats making a difference in sound level (i welded in striaght pipe where they were, its not just open) however it has given the truck a slighly better sound. As for the mpg's it will not be affected, the truck has 2 sets of O2 sensors, one before the cats and one set at the cats. The sensor before the cats is what would have impact on fuel trims, i have already deleted the rear 02 Sensors so that a code will not be thrown with them gone. Without them it slighlty reduces restriction on the outlet side, not much, but worth taking them off imo. I will checkout the magnaflow and corsa, thanks!

High flows would have been a better choice imo.

Yea I did consider those, decided to just cut them off and scrap them, figured the $ I got for them would pay for some of the exhaust

I have cut my cats out and didn't notice a difference in mpg or power. I have never looked back since. And i would reccommend you looking into MBRP. They have a real nice sounding exhaust. I always say youtube is you best friend for exhaust shopping. there should be tons of videos of different exhaust set ups for your truck.
