Fantastic muffler 2.5 inlet & outlet. Solid construction. Tap on it out of the box and it feels and sounds Solid!! The packing inside is engineered to mitigate droning and raspy wide open throttle shrieking that can happen with four cylinder engines. Sound is at a very comfortable level and the neighbors dogs are happy too! Great product!! Read more

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. Read more

Great muffler, choose the long version of the muffler to try and match with my OEM muffler. Looks great and sounds great and has a low rumble. Read more

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. Read more

This has a nice rumble on a Toyota 4Runner with the 4.7 V8. No terrible drone on the highway and sounds good at idle without the resonator. Read more
