5Flowmaster 40 Delta Flow Muffler
By Jeff Smith
I bought this Muffler for my 2001 Jeep Wrangler to replace the muffler on my aftermarket Banks Monster Exhaust. my old muffler lost all of its packing after a few years and developed a loud drone inside. I assume that muffler burnt out because it is immediately after the catalytic converter and the heat was too much for it. The flowmaster is a chambered muffler (no packing to burn out) so I am not concerned with it getting louder over time. The sound is good, not too loud but you can definitely hear it inside, although once you get up to speed with a soft top everything is loud. if I had the hard top Possibly would go with the 50 series

5True V8 sound w/o too much noise
By Wolfgang Grebenhof
What an improvement! With the Flowmaster series 50 Delta Flow mufflers, my 1996 Buick Roadmaster Estate sounds so much better - and it still is nice and quiet inside at cruising speed. Just as described on the Flowmaster homepage, and just as expected. Those mufflers are worth their price.

5great sound!
By antero21
Installed on a 70 chevelle 454 and sounded great! We removed 40 series mufflers because they were too raspy. Customer is very satisfied!

5Nice Muffler...
By Cherokee98
Fit nicely on 98 Cherokee Sport. Sounds really good as well. I would recommend to anyone that wants to liven up the exhaust.

5Bought for my 1998 Jeep Cherokee - Sounds Great
By Michael R. Johnson
Bought for my 1998 Jeep Cherokee with 4.0L I6. I originally had the stock cat that was setting a P0420 cat Efficiency Code attached to a Pypes Violator Muffler from a mustang gt. I cut all that old stuff out and put a magnaflow directfit cat paired with this exhaust and it sounds great! Definitely recommend this product if you want a good sounding muffler that isnt too loud. Definitely quieter than the pypes muffler. Recommend using the oem tailpipe and not dumping before the axle because it is much quieter in the cab when the exhaust is routed to the rear.

4this muffler is NOT stainless steel
By Mr. Clean
I've been researching this series for installation in my muscle car. The 942451 (just like all the 942xxx mufflers) is aluminized steel, NOT stainless. If you want the STAINLESS STEEL mufflers, you need to purchase the 842451 (or 842xxx, depending on which one you want). It looks like they are about $35 more but, being stainless, they'll probably last forever.This is the second incorrect description I've seen here for the 50 Series Delta Flow mufflers. If I were you, I'd check the Flowmaster website to make sure you get what you REALLY want.

4sweet mufflers
By larry russell
I put these mufflers on my 1964 cutlass vista cruiser that I restored , they gave it that old time hot rod sound without being too loud.

5Great Product
By Bam
Put this on a Ridgeline and other than being a tad on the quiet side sounds perfect. Gave it that low growl I was looking for without making it sound sick like alot of V6 with aftermarket mufflers.

5They sound Great!
By Gregg Gilliam
I got these for my son-in-law for Christmas. He has a 1997 Thunderbird with a 4.6 V-8. I got him a pair of them and he had them installed. It has a nice rumble when idling and sounds aggressive when he nails it, but it is not obnoxious from inside the car either. These are nice!
