Dynomax Super Turbo 17748 Exhaust Muffler

This is the second one of these I have bought for my 04 Jeep Grand Cherokee. First one lasted 4 years which in Michigan where the roads are literally covered with salt 6 months out the year is quite good. Has a real nice mellow sound, throaty at idle but with NO drone at all. Makes my 4.7L Jeep actually sound cool. Those complaining about the fit seem to forget this a universal fit muffler, it was not made to just bolt in perfectly replacing the factory muffler.

These muffler sound perfect, nice deep tone rumble at idle . They sound great when you punch it with out the drone when Cruising . Highly recommend for big block applications.

I bought this to replace a 2 year old flow master muffler that I hated from the moment i put it on. This Dynomax looks to be of similar quality and cost about 1/3 of what I paid for the FM. The FM was a little louder and did sound really good outside of my truck, however the drone inside it produced was horrendous. This Dynomax is very quiet inside my truck. No drone whatsoever. I can now hear myself think and carry on a conversation with a passenger. The sound outside of the truck is still aggressive over a stock muffler, and still growls if you step on the gas. Id highly recommend this muffler for anyone wanting a classier, deep, non trashy rumble. This is not for someone wanting their vehicle to be obnoxiously loud. Just a note, I installed it on my Dakota with a 4.7 V8.

built solid. sounds great. its a bit louder than the stock muffler but not to the point were your neighbors will complain all in all great product
