Good Sound

Summit RacingSummit Racing Verified Purchase

Install was fairly easy, I replaced an aftermarket exhaust, so I don't know how easy from stock to this exhaust. The hanger instructions were a little confusing. The sound at idle isn't too loud, but when you open it up it'll scream.

Dynomax exhaust

Decent quality pipes and muffler. Not crazy about clamps supplied with it. Directions were barely legible. Overall not bad for money.

Quality Product - Prompt delivery (as usual)

Summit RacingSummit Racing Verified Purchase

I ordered this to replace a system that had served well but had reached the end of its useful life. My truck has a V6 and I was looking for a milder tone This system met my expectations perfectly. It was delivered in 2 days. It arrived in great shape and upon opening it everything was in the box as it should be. My install was not as straightforward as I had hoped but that was due to modifications made previously and not the fault of the kit - otherwise installation went smoothly. The supplied clamps are quality pieces and the fit is great. there is plenty of adjustment available to get things "just right" My only complaint was with the images found in the instructions - they were completely illegible but the Dynomax website has them available for download that are actually readable. I highly recommend this exhaust system. ...read more

Not bad for the Price, but Not Great either

Summit RacingSummit Racing Verified Purchase

This system seems pretty sturdy for the price and is stainless steel, which is a must if you live in the "Snow Belt" Northeastern US. I had another system on my truck that Summit sells, but it only made it 3 years and less than 25,000 miles before it fell to pieces from the rust. That other system, ****master, are really over rated and I will never buy another one of their exhaust systems again. So far I only have two complaints about the DynoMax system. 1. The banded exhaust clamps are not the greatest. I know they are suppose to be the new thing, but these ones are difficult to make a good clamping seal. I broke two of the bolts trying to tighten them down and I still couldn't get the pipes to clamp together without them still moving around. 2. The exhaust tone is just plain and weak. They need a more aggressive deep tone muffler for these systems. However, the other companies muffler was the same way, until I replaced it with a super44 because the muffler that came with their system rusted out and broke off around 2 years old. All in All the DynoMax seems pretty good so far, but only the northeastern winters will decide the final verdict. Stock exhaust....lasted over 10 years. Other company exhaust (not SS).....less than 3 years. DynoMax.....we will see. ...read more
