Muffler Upgrade Question!

[YukonXL04]

I had a flowmaster 40 series on my 04 5.3 and loved the sound and had it and a new dual tip welded on for 80 bucks included cost of the tip. only reason I went with a flowmast is cause I got it off craigslist for 20 bucks lol also have never had anything against flowmaster.

My 08 with the 5.3 has the Borla ProXS 40359 and it sounds awesome even with the resonator still on. that only cost 40 to install.

120 is ridiculous to just weld in a muffler, I'm sure you can find a cheaper place. I've learned to order the muffler I want and take it somewhere. 99% of the time its way cheaper.

I really like my borla proXS. I do wish it was a little louder at WOT. But all in all it has a great deep tone to it, and sounds good. slight drone, but less drone than anyone elses truck I have been in with various muflers

Hmm. The ****** seems like a good route

I have a Flowmaster super 44 3" in 3" out with a Flowmaster 5" tip. Its loud and gives a real deep sound. But does drone at 2k rpm.

The torque numbers on the borla xs are awesome on the low end. Those numbers seem noticeable in every day driving
