Dynomax 89007 Exhaust System Kit for GMC C1500

Works good for my truck

The overall rating for me is 5 stars.Correct bends, every bend was precise and lengths were also accurate—just enough hangers, brackets, and clamps to complete the job with no waste. I bought a really cost-effective set of thrust mufflers to complete the job, They sound great with a little rumble out the back and quiet inside the truck. My truck is an 81 Chevrolet C10 "Square body"

Just a great fit. A little work putting the exhaust hangers on but great system for the money. I used the Dynomax headers and Dynomax super turbo mufflers also. Around $275 (not including Headers) for a complete dual exhaust system! Great deal!

I had totally rework this kit too work with my c10 with cheap headers off ebay if do same got lot pipe cutting and stretching and welds

First of all this kit is a 2.25 inch exhaust kit. It’s a bit misleading, so trying to use my 2.5 mufflers didn’t go well. I was able to use adapters, but I ended up ordering 2.25 mufflers. One of the pipes was not flared enough to fit one of my headers. I had to go buy an expander to make it fit. The hardware is junk. If you do buy the kit, go to the local parts store and get hangers and and clamps. Overall for the money, it’s not bad versus 400+ dollars at the exhaust shop. I wouldn’t buy it again, but I will make it work.

I’m building a 75 ford f100 and was able to create the perfect leaf cutter exhaust style. This was a recommendation from my dad who purchased the same kit for his first generation bronco (66-77)

You get what you pay for. Cheap stainless, ad says its 3'' tubing but my package came and tubing was 2 - 1/4''. Still going to use on my truck but, do not expect this to be top of the line exhaust.

Sounds good as well

Kit arrived quickly and no damage to box or anything. Will be installing in the coming days...should do the job...

Right, installed this on my 1976 Chevrolet C10 Scottsdale long box 2wd automatic transmission. Everything worked and lined up as needed. I had to cut 5" off the driver side exhaust to make everything line up, but that took 30 seconds with my recip saw. I would do yourself a favour and pick up a few extra exhaust clamps, and some proper hangers, as I had to cut my old ones off. Otherwise this kit is good to go.

The hardware kit is a joke missing nuts wrong size washers.if you don't have a welder you will not be able to install
