Exhaust Pipes
So I have been thinking of a way to re-do my rusty old exhaust pipes and LMC puts out a kit for a complete system.
Part Number 36-5526 see here: http://www.lmctruck.com/icatalog/cb/full.aspx?Page=157 Has anyone used this product? If so, are the pipes made to use the stock Diverter Valve for Exhaust Gas to heat up the motor? I called them and the guys answering the phone had no clue, and they have no technical specs or drawings. Any info is appreciated. Seems like a decent deal for a complete system on a stock motor. |

Re: Exhaust Pipes
That kit is made by Heartthrob Exhaust in Minnesota. http://heartthrobexhaust.com/manifolddualkits.htm Call them and ask for Mike. He'll answer any questions you may have. Then shop someplace other than LMC. Try http://www.autoaccessoriesgarage.com...?set-vehicle=1. You can get 15% off with free shipping.
I bought the "stock" mufflers with exits behind the rear wheels. They are not nearly as quiet as stock mufflers were. As I recall you can install them with or wirhout the factory heat riser. I did it without since I have a Holley and GM Performance Parts intake. The system is high quality, but I elected to use band clamps from Summit Racing instead of the included run of the mill clamps. EDIT: My truck is a 69 3/4 ton with an Eaton axle. The kit is not designed for that application. I wasn't aware of that when I ordered. I worked with Mike at Heartthrob and sent him a pattern. They custom bent rear pipe for me at no cost. The stock mufflers are designed to be installed on edge, not flat. That's the way my originals from the factory were oriented also. You may also need to install a new style mini starter for clearance on the right side. Last edited by FirstOwner69; 01-12-2016 at 07:47 PM. |

Why not just go have it in stalled at a shop?

Re: Exhaust Pipes
I put the Hearthrob kit on my 72 K10 w/350. Was a perfect fit. I bought mine from autoanything.com with a 20% off code

Re: Exhaust Pipes
Andy that is the thought, yet I am still way far out until I get a 6.0 setup into my rig.
I kinda have to fix what I have for now. One can only do and dream! |

Re: Exhaust Pipes
Shops are just as cheap sometimes as a kit. I personally like the shops install when everything is a welded connection.

I stopped at a local muffler shop and asked about having duals ran all the way out back from the headers to the bumper, he asked which mufflers, i was gonna go with flow masters, he said he had nothing but rust problems with them, told me to buy two stainless steel mufflers and he'd do it all for $275.00! Works for me!

Re: Exhaust Pipes
I had fun doing my own... Ha. I bought the mufflers I wanted, some 2.5 inch pipe and bends and went after it. I have a lift, a welder and a cutter so that helps. You can get creative and run them very nice and tucked up so they cant be seen. It took some time to do it right but that is how I have done most of my stuff.

Re: Exhaust Pipes
I did Stainless Works 3" on mine. Love it. Did a little bit of fab work because I have Blazer tank .

Re: Exhaust Pipes
I would definitely ask some of your local car and truck guys who they use. There was a guy here that seemed like he did everyone's ... at least everyone knew who he was. Very reasonable prices, and such a nice tight fit. No ugly pipes hanging down. He's since retired though.
