Review: Inlet..outlet sizes. - Not too loud.. not too quiet... straight through mufflers are the best for air flow and sound...I cleaned the throttle body and IAC thoroughly and Installed a spectre oiled air filter and new plugs and wires now I can tell the difference in idle and acceleration... I wasn't expecting major improvements...after all the truck weighs in at over 5000 pounds empty... so I made the right choice..with magnaflow 12256 and 24 inch turndown... I used a micrometer to measure inlet and outlet sizes on my truck exhaust pipes... just to make sure...and double checked the new muffler to make sure that it fitted too...so I didn't have to add all kinds of adapters and reducers and all that... nah!!! It just slid right on.... and bolted right up... do the homework... 5-24-20 UPdate: after 2 years later and it sounds even better; more of that throaty sound we like. No drone... I used u bolts and did not weld it on and they have held just fine without no exhaust leaks or looseness. I measured how much exhaust pipe to cut off and how long the tail pipe needed to be to extend past the truck cab and no fumes got into the cab. Do the homework.
Review: Under hard acceleration it has a nice bark, but once again - Installed this muffler first on my 94 Dodge Ram with V6 engine in place of the factory muffler. While somewhat louder while cruising, the noise was not excessive or distracting. Under hard acceleration it has a nice bark, but once again, nothing as obnoxious as a straight pipe or glass pack set up. When I sold the fullsize, I installed on my Dakota, same year and engine. It is much louder on this truck, but the exhaust is dumped much closer to the back of the muffler. I would recommend this muffler to anyone who wants a nice performance sound without excessive cabin noise while cruising, keeping in mind that the rest of the exhaust system may need tweaking to get rid of any resonances. The construction of this muffler is simply beautiful. The welds are all properly sized and placed, which as a welder pleased me to no end.

### ⭐⭐⭐⭐ Very nice, but not loud enough for me
*by G***R on August 15, 2015*

This is a tough review for me. The muffler is very high quality and fit my '03 Wrangler with 2.25 to 2.5" adapters. I must say that while it did give a nice deep rumble, it was simply not loud enough for me. I was looking for something with a little more juice! I've ordered a Magnaflow glasspack to replace this. We shall see how it goes. This is definitely louder than stock and the tone is very nice. On a scale of 1-10 with 10 being obnoxiously loud and 1 being very quiet, I would rate the stock muffler at 1 and this muffler at 3. Like I said, I'm looking for something more in the 6-8 range.
