Aftermarket or custom exhaust system?
For the entire piping. I don't remember the estimated cost for my 72 C10 but looking at aftermarket ones are way cheaper. Are aftermarkets any good? Which ones would you recommend if you went aftermarket? Or just drop the doh on a custom?

Re: Aftermarket or custom exhaust system?
Around here going to a muffler shop and getting it done custom with aluminized steel is about $500 to $600.

I used the full 2.25" dual turbo muffler system from LMC on my 1970 K/5 Blazer with 350. I installed it with the body off the frame, but experienced no fitment issues. i bought it in 2021 for around $300.

Re: Aftermarket or custom exhaust system?
Back around 2016, I bought a HeartThrob mandrel-bent, aluminized, 2-1/4" system for a square body. Very reasonable price (a little over $200, I think) from one of their distributors, but I forget the name. I even spoke to a guy named Mike, who was the one who would bend my pipes. I did have to fabricate the head pipes to connect to my 97 Vortec exhaust manifolds, but the rest fit very well. This is their list of manifold duals, but they also have header duals. Go down a ways to see GM/Chevy.
http://www.heartthrobexhaust.com/manifolddualkits.htm They also make their own mufflers, but I wouldn't recommend them.

Re: Aftermarket or custom exhaust system?
I didn't like anything I saw available, so I bought 2.5 inch stainless pre-bent sections and Magnaflow 14x6 round mufflers and built my own. I don't think I'd ever do it any other way again.

Re: Aftermarket or custom exhaust system?
I used a 2 1/2 stainless kit from Pypes and then customized it to tuck between the frame rails and I put in electric cutouts. I used Thrush oval turbo mufflers.

Re: Aftermarket or custom exhaust system?
I bought a 3" mandrel bent 180 from Summit Racing, and a 10 foot stick of 3" tubing from my local exhaust shop and fabricated my own with Flowmaster 40's.

Re: Aftermarket or custom exhaust system?
I have an exhaust shop I have used for years. Always comes out nice. It costs a little more but he fights getting around the transfer case. I just drink beer from his fridge...lol

Re: Aftermarket or custom exhaust system?
That's a good shop! Back in the day I had a customer I liked to call on just before quitting time. At 5pm he always opened up the Coke machine that had a bottom full of beer bottles!

Re: Aftermarket or custom exhaust system?
Normally, an exhaust that is purchased off-the-shelf will be mandrel bent, not not 100% of the time. An exhaust from a local shop will generally always be bent with a standard pipe bender, but not all the time.
Most people like mandrel bent because it is cleaner looking and has better flow. I found a local shop that had a mandrel bender, but when he told me the price, I bought all the 3" tubing, a cheap tig welder, the tank, and all the other items needed to built it myself for just a bit over 1/2 the price he quoted me. |

Re: Aftermarket or custom exhaust system?
I don't even know of any shops in the Dallas/Fort Worth area with mandrel bending tools. One shop claims to do mandrel bending, but what they do is buy the bends and then weld together the systems.
I had few bends left over from my HeartThrob kit and also bought a few more somewhere on line. But just recently, the guys on Engine Masters did a dyno test and said there was virtually no difference between mandrel bends and muffler shop crush bends. Then again, that could have been a 3" system when 2.5" would have made the same power with that specific engine. So, I'm not buying that for crush bends of all sizes for all engines. That, and mandrel bends sure look nicer!

Maybe... depends on your definition of "loud".
