🚘 Flowmaster 430402 3In (C)/2.5Out (D) 40 Series Muffler - Optimal Performance & Noise Reduction Review

This muffler has a great sound with Hemi 5.7, it's not too loud but definitely loud enough to let people know you're there.

Easy install, sounds like it should come from the factory. My Hemi sounds like Hemi now. Seemed very well done without breaking the bank.

Amazing product for the money and the exhaust, they tried to charge me 210 dlc for it and I was like hell, found this one for a much lower price and next day delivery ! Put this on my 2018 Ram 1500 and it sounds fantastic!

I was looking for this in a 3 inch dual out but the 2.50 definitely does the job. I think it's definitely gotten louder since I bought it a month ago, some people might disagree. Not so bad in a drone. You can hear it most around 1700-2000 rpm, almost just before it wants to shift, or around 77 mph. I bought this for my 2002 Chevy Silverado 1500 5.3L V8. If I were to do it again I would make my exhaust a true dual and still use the 40 series.

After researching different exhaust options I decided to swap out my Avalanche's muffler rather than go with a full reverse system. I really like the sound of this muffler and I highly recommend it.

It gets quite loud under hard acceleration, but the sound is deep and aggressive, and there's no rumble while driving, which was important to me.

This is a classic and iconic muffler for all truck owners who want to fit dual tailpipes and get a nice deep rumble. I put this on my dad's 2004 Silverado 5.3L after removing the catalytic converters and it really roars like an old school truck. Sounds great when starting, idling and in motion. Full throttle isn't as loud as other makes of truck, but I think it's common with Chevy LS engines. All in all this is a great silencer and it was a good buy. I would recommend finding a stainless steel…

Installed on my 2015 Hemi Dodge Ram. Sounds fantastic. Good-natured and aggressive, but not too loud. I wanted something that would let me just hear Hemi without upsetting the neighbors. With this muffler you will need a 3" pipe (I think it was 16 or 18" long, bought from Pep Boys for $16) and two 2.5" muffs that cut to 2.25" ( 2.25 - this is the standard exhaust pipe size after that) shrink the muffler.) I'm a very amateur welder with a special Amazon $100 cup welder, but I welded them from…
