I bought this Dynomax exhaust kit about a month ago.I have an 84 Chevy k10 pickup long bed.I installed this kit using stainless steel exhaust headers from pro comp and stainless steel mufflers from flowmaster. My only complaint with the kit is for long bed pickups they include two front tail pipe extensions that have a slight bend in them. That worked fine on the drivers side but on the passenger side the pipe needed to be straight. So I had to go to Pep Boys and buy a 3 foot piece of straight two and a quarter inch pipe and cut about 10" off. Other than that one thing this is a great exhaust kit.
Easy installation all the hardware was included sounds good with jegs deep tone mufflers.
Everything fit good except the left pipe that bolted to the header wasn't bent enough. I had to cut, bend, and re-weld it to make it contour correctly. All in all a good deal vs muffler shop charges
Fits really good with 387-11500 headers. And ran pypes m80 14" glasspacks happy with outcome. Just wish it was a little louder
I bought this kit KNOWING it was cheap and likely wouldn't fit perfect but I needed an exhaust quick and my budget was running thin finishing my truck. One side for pretty darn perfect the other side wasn't bent right where it goes over the crossmember and totally through off the exhaust the rest of the way back. My muffler is almost sideways and I ha to fabricate a hanger from 1/8" plate to make it work. Besides the bad bends, the joints are too sloppy and each one has an exhaust leak. I'm going to drop it all and re-work it and weld it in now. If I had to do over again is buy a higher end kit or get an exhaust shop to do it. BUT if your wallet was thin like mine it can be done but I tec omen welding the joints an tossing the clamps.
First off gotta start by giving Jegs a huge atta boy, their customer was phenomenal, had issues with the first kit I ordered called Jegs and had a new kit 4 days later. But now onto this kit, so many things were bad, terrible fitting parts, flimsy clamps; I had to cut and modify so much of this kit, I ended up tossing about half of out when all was said and done. Morale of the story spend the money for a far superior kit and definitely skip this one!!!
Have an '86 k10 pipe goes around the transfer case fine but is a bit high. With mufflers on and extension it goes right into the suspension mount. I dont know what your supposed to do with the left. The straight pipe hits the crossmember and the bent one is the same as the right so you can hit the tank or transmission and be very low. Don't think this will get you going one night after work.
