These were a great price and easy to install. I’ve had cherrybombs before in another truck and those we’re great to but I needed a short study pack because of space and these worked perfect. The reason I bought these was to put something to quiet my truck a little and it did. I have long tube headers on my Silverado so it was pretty darn load! But these packs give my truck a long drawn out tone instead of a loud popping sound.

I have an s10 with an ls swap. The exhaust is piped to a flowmaster 50 duel inlet single 3″ outlet. No cats. I’m running a big cam. At 2000rpm the exhaust drone rattled your head and ears! It buzzed the windows and interior. I slipped this resonator on the tailpipe behind the rear axle and boom! Stopped that drone dead in its tracks! Improved the sound by mellowing it out and lowered it by a few decibels too. I like it!

Just replaced the two mid mufflers on my 392 Challenger scat pack and wow do these sound good. The idle is like 10% louder than before and full throttle like 20% louder. Not raspy at all they sound clean kind of like a purring gargle. No need for a $2k aftermarket exhaust just drop these in. The inlet/outlet isn’t marked so I called dynomax and they said the long end is the inlet with short end the outlet don’t put them in backwards!

I only had this on my 2012 Silverado 5.3 for about 2 weeks but I loved every second of it, really gave it that truck/muscle sound and for at the time I purchased was $20 couldn’t not beat it. I will buy another for my 2015 ram shortly.

I used these to replace the mid-mufflers on my 2021 Challenger Scat Pack. Very pleased. Just the sound that I was looking for.

honestly for how cheap they are you can’t beat them, I put them on my 2015 dodge charger rt and I’m more than pleased with them. only thing is I just wish they labeled which side was the inlet and outlet but its easy enough to look it up and figure it out.

I have straight pipe on one challenger and decided to try these on my new challenger and I could not be happier.
