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.

needs better instructions.

Summit RacingSummit Racing Verified Purchase

Love the sound. Fit was good, instructions are not. Clamps not labeled in the instructions as to which style went where. No bolts for the rear hangers, but a set of bolts about 3 1/2" long were included. Not used on this truck. I would still recommend the system. I have a '98 F150 with the 4.6l. engine. Manufacturer needs to fix the instructions. ...read more

Straight Forward Install

Overall this was an easy install and the exhaust pipes fit very close to the factory set. Not too loud that at idle but if you lay into it they have a great sound

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
