Flowmaser 40 muffler for Dodge Challenger R/T.

I ordered a Flowmaster 40 muffler for my 2010 Dodge Challenger r/t after the Dodge dealer said original muffler was discontinued. Turns out the Flowmaster is an exact fit. The Hemi sounds great. Not too loud and sounds like a musclecar should. I've bought parts from Jegs for 30 years and have always gotten great parts at great prices.

You have to own these. Matches my Harley sound now.

Easy directions. Put this cat-back on in a couple of hours. Taking my time. Perfect fit. All parts were in the box. Quality product that sounds great. Welded up when finished as Flowmaster recommends. [This review was collected as part of a promotion.]

Happy muffler customer

This item is just as we wanted. It was like half the price at Walmart than anywhere in my town. It fit perfectly. The delivery was a day earlier than scheduled.
