GMPP Touring Muffler

[txdox21]

I had the GMPP Touring muffler installed last night, and so far I am liking it a lot. I have gone back and forth for 2 years on whether or not I wanted to change the muffler, and finally pulled the trigger. I ordered the muffler from Borla. I know a lot of people are on the fence about which muffler to install for a little more sound without drone, and I would definitely suggest this muffler.

 

The truck sounds much better at start up and idle. When accelerating, you can definitely tell a difference (not wake up the neighbors loud), but as soon as you start to cruise it is silent. I have noticed that my truck seems to switch to V4 more often and stay in V4 longer than before. The most important thing is that there is no drone and that you really have to pay attention with the a/c and radio off to hear when it switches to V4.

 

I will see what I can do about getting a video posted.

This is the muffler only. The muffler is stamped "GM Performance Parts"

Looking forward to a video of your new muffler sound. I haven't been ableto find the GMPP system for the new trucks, but defintely liked the one on my previous 2005 Sierra Crew Cab. Sounded awesome when accelerating and was smooth while cruising. I see you are in Texas. Any chance you had the muffler installed in Houston? Any issues with Midas welding it into the stock location and you keeping the single exhaust?

You can buy the GMPP Touring and sport mufflers from Borla. I believe you can order the entire system as well, but I went the cheapest route possible just in case I didnt like the sound.

 

I had it installed in San Antonio. They had to add a small (2-3") elbow to line up with the stock piping. They clamped the back side of the muffler to the piping. I am going to check for leaks around the clamp and may have them weld it too. I didnt notice that it wasnt welded in the back until I got home.

The part number for the sport muffler is 19131347. A muffler of the same dimensions is sold on the Borla site for $200, while the gm labeled is $73.

Better off going with this over Magnaflow. I have the GMPP full cat-back sport kit on 08 v-max and it sounds great. Can't go wrong with this muffler at that cost.

Curious why the sport is $20 cheaper than the touring.

It's 1" smaller in diameter, less material used maybe???

[Chris]

I'd bet it should cost more because its free er flowing or something. I may have to order one monday

Awesome. Look forward to hearing it. I'd really like to add a bit of sound to the rig without the constant drone.
