Howdy all..

 

Just curious what (if) everyone is running for a cat-back exhaust system.  I am partial to Borla because that is all I have ever run on my Camaros and other trucks.  Plus, does not void factory warranty.

 

Borla has a system thru GM p/n 19420409 which looks okay because it has the black chrome tip on it (would look nice on a red truck).

 

Did some searches thru Magnaflow and Corsa.  Not really a fan of Flowmasters.

 

Looking for opinions and recommendations.

 

Have a great weekend all!

A nice cheaper option would be buying a 3.5 inlet/outlet borla xr1 round muffler and a piece of 3.5 in stainless pipe from summit racing and bring it to your local muffler shop to have welded in place of the factory muffler. It sounds really good and looks stock from the back of the truck.

I have MBRP cat back on mine - I like it alright, sounds good, only thing I don't like is that no matter how many times I tighten the clamps the exhaust likes to move and rub on the guard next to the spare tire.

 

I actually would have considered going with the stainless works option as it sounds really good and is also 305 stainless which was the key factor for me as I only want to do it once.

 

The Borla option only sold by Chevy dealers wasn't available initially but is also a bit too quiet for my taste.

I went with the Flowmaster Outlaw stainless dual exhaust system and I love it. The price was right as well and I installed it myself.

Welding the joints would eliminate the need for clamps?  Would be the way I go I think....wouldnt always want to go under and re tighten all the time.  I'm still debating.  Borla says they have something coming out soon for our trucks.  Have decided not to go with the one from GM (Borla).

For what it's worth Borla has been saying that for two year's now and never give a straight answer as to when.

Has something new that I was intrigued by and would consider if I was still looking.

Not on a 2020+HD but on my 2015 HD and my 2019 old body 1/2 ton, I had Corsa catbacks on those and after installing and running for about 100mi, I just checked the tightness on the clamps at 100mi after install and that was it.  Never had one come loose, leak, etc.

Have tightened numerous times - still happens.  Have 35's and live on a rough road so that doesn't help I'm sure.

      Clunk when putting truck into drive and reverse.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
