Did not fit my 2007 Dodge Ram 2500. This is a universal muffler and you need to modify, this should have been stated on the ad. I thank you for taking it back. I then ordered the Walker muffler through amazon, had it installed in 30-45 minutes. No problems.

This is a Universal fit muffler, 4" inlet/outlet, about 10" wide and 18" long case. It is meant to be installed as part of a custom exhaust system where you want a more mellow exhaust tone. I've installed on a couple of tow vehicles so far that the owners wanted to improve performance while still being able to hold a conversation in the cab of their pickups while pulling a load up a hill, and have had no complaints so far.

The owners also reported a seat of the pants improvement in pulling power and slight increase in fuel economy, but this was with a full 4" catback system (stock was ~3") and not necessarily a result of the muffler by itself. That said compared to the massive and restrictive factory mufflers on some of these trucks, it's easy to see why this little muffler would improve exhaust flow and therefore performance.

I's sure it's a perfectly fine muffler, but it didn't fit our pickup. My husband specifically ordered for a Dodge Ram 2500 Diesel, and we aren't sure what it really fits.

Thank you Amazon for supplying the return label and taking it back.

The old muffler was in one side and out the other but was not a problem. Changed the pipe in front of the muffler. Has a nice tone on a Dodge diesel dually.

Product was as described and sounds great. Not that much louder than stock. Noticed a big difference in power from a stop when towing.
