Pre bent exhaust for our trucks?
Does anyone make a bolt on 2 1/2" exhaust system for our trucks? I prefer mandrel bent over the local exhaust shop bender. Names like Flowmaster, Magnaflow, Heartbeat, do they make em for our trucks? How well do they fit?

Re: Pre bent exhaust for our trucks?
I thought Magnaflow's kit went over the axle- all stainless!
Jay, I can't wait to get the details/pics!

Re: Pre bent exhaust for our trucks?
Yes Magnaflow has a kit. LMC carries it. Once you get the part number, plug it into an Ebay search. It's sold by a few Ebay sellers.
It's made for longbeds, but can be cut down for shortbeds. Pete |

The only piece I needed to buy that wasn't included in the kit was an exhaust hanger because my truck was NOT a factory dual exhaust truck. The LMC kit was made by Heartbeat here in Minnesota.

Re: Pre bent exhaust for our trucks?
The Magnaflow setup is for coil spring only, but I don't remember why. I'll look in old emails from them and find out. IMHO, it's one heck of a deal. It sells for ~$500 through Summit. Their Dyno showed a 10 HP and 22 lb/ft gain in torque. It's an all stainless, mandrel bent kit. Great product!

Re: Pre bent exhaust for our trucks?
Classic Trucks magazine did an article on the Magnaflow kit on a 72 they have been working on. Here is the article.

Re: Pre bent exhaust for our trucks?
Kewl, I do have a GMC truck with rear leaf springs, but I am switching it all over to a 71 Chevy frame, when I decide to do the body off restoration.

Re: Pre bent exhaust for our trucks?
im confused why people want to spent double the amount on pre-bend exhaust systems, just so they can say I have a borla or magnaflow systems. I wonder If Dale jr. buys his system out of a catalog as well? It doesn't matter who makes it, what matters is the diameter of the Pipe and what mufflers you install. A full custom 3in installed system will cost your at a reputable Muffler/Fab shop $250-300 plus Flowmasters. Now with the saved money you can buy yourself a nice camshaft for that extra 40 hp

Re: Pre bent exhaust for our trucks?
Because up here in Indiana they salt the roads in the winter, which make sh** rust. Even though I don't drive my truck in the winter, it still sits on a concrete floor and begins to oxidize. Plus it looks better and performs better and lasts longer. I like to do things right the first time.

So... pay an exhaust shop 300 + buy your own mufflers = $400? For an extra 80 you get a stainless exhaust system, an x-pipe, and an over-the-axle exhaust system. That seems like a pretty good deal to me. Last edited by Jim_PA; 09-06-2007 at 10:30 PM. |

Re: Pre bent exhaust for our trucks?
Bayer, now you have me curious. What place did you get that job done? Was the pipe stainless steel, aluminized or something else?

Re: Pre bent exhaust for our trucks?
You can call this place...Summit also started carrying pypes. I just got the kit for my 56 belair a few weeks ago. All SS with the xpipe and ecutouts. Just throwing another option out there...I'm pretty happy so far.

Re: Pre bent exhaust for our trucks?
Mandrel bent has a lot less restriction. The local shop uses the hydraulic bender which slightly smashes and crimps the pipe, thus restricting exhaust flow. Gain or lose 10-20 hp it's up to you.
