I really want to cut my 3rd cat out but I really don't want to tune this thing yet..

Hopefully my dealer knows this..they did have four 5.3L trucks on the show floor with dual magnaflow exhausts kits and they all looked good.

I wonder if your dealer would sell me the kit they are taking off of your truck?? Like cheap! LOL Ask them how much for me next time you talk to them. I call dibs if its a smokin price!

You won't need a tune with a third cat delete.

Thought I read someone here had to tune because it left them running a little lean? Maybe not.

Any word on if DB exhaust has anything in the works? I just emailed them and am waiting to hear.. curious if anyone else heard anything. I want to order a gibson or aFe but just can't click that buy button as I have run Corsa on my '05 and LOVED it. I also can't click the buy button with a $1,000 Corsa sitting in my cart. Hoping DB comes out with something in between.. can't wait to actually hear this truck.

I believe a user on here said that his tuner seen a Fuel Trim swing in his calibration but I did as well which was a whole 2.5%. You will see trim swings like that with changes in temperature, altitude and humidity which your ECU is perfectly capable of adjusting for. That's why it has Fuel Trims. ;). Will you gain more from a tune? Sure... It's just not necessary for that modification.

Thanks for the pics. It does look like it sticks out a couple inches farther than my stock tip. Though it doesn't really look that objectionable to me--especially compared with the megaphone-style tips the stock duramax's come with. Tuck it in a couple of inches and I think I'll like it just fine.

Damn those wheels!! I freakin love em!! Fine truck you have there! Yeah, I absolutely despise Flowmaster. Been around too many dyno tests where results were not so good. Some cases were less than stock.

I can confirm this as well but I only seen truly negative results on the F-body cat back cross flow crap... especially when compared to Magnaflow. I run flowmaster because I like the sound and on comparable dual exhaust setups, HP differences on my Dyno may have been a little less at peak HP but the curves were very comparable. The differences weren't worth it to me to give up the classic sound.

Yeah, I'm not a fan of that look... I just looks like something you could buy at PepBoys and stick on there! I like this much better.........
