Dynomax89003 Exhaust System Kit for GMC K1500

Installed on '84 Chevy K20 used 76 manifolds. The pipes fit fine in the chassis.Could use a couple more hangers and clamps. Clamps in the kit are cheap you need to buy 4 ⅜" clamps for mufflers and 2 360 swingers for tailpipes before install. shipping box was beat up with holes and all loose parts in a plastic bag or floating loosely in box how all the pipes made it is still a unsolved mystery

Customer service was great and the parts look good. Haven't fitted it all together yet but seems to be great quality for the price.

Should work for a couple years??

I used this on a 1995 gmc c1500 short bed with a 350 with stock manifolds I needed the 90 and the 45 down pipes and everything else was extra didnt go as planned to have the bends over the axel so I shorted it to axel dumps but overall very nice kit for the price the clamps are a bit weak and dont crimp to the pipe well and I did break one. hangers seem alright but idk how well they'll last.

Passager side fit pretty good had to buy 2-18" pipes to exit over the rear and out the sidesDriver's side is a different story had to buy 2 -45° to go over the transmission mount due to the pipe mounting directly into the mount clamps will not tighten to seal sounds good but I guess you get what you pay for!!

Good material, all parts I needed were here. The only thing to consider is buying mufflers after you receive the pipes so you can get a proper length muffler.

Great sounding exhaust, would buy again and would recommend!

Using the Dynomax 89003 universal duel exhaust kit with the Dynomax 17731 super turbo mufflers for my 1987 chevy short bed frame off restoration, used on this vehicle before fits well and sounds great.

Fits like a glove! No need for instructions, really. It's not top quality but it works fine.

Bought for 1985 Chevrolet K10 Long box Pickup also purchased the recommended mufflers in the instructions , and it was not long enough on drivers side. Had to buy more exhaust pipe to make it work. Mounts and hardware are garbage. Had to buy better hardware elsewhere also. Save yourself some trouble and buy a more expensive, better exhaust kit.
