Louder than expected, Super 10 Super Happy

Replaced my 40 series with this Super 10. Huge difference. Sounds freaking awful, honestly thought it wasn't loud enough, but it's perfect. The product arrived on time and was installed on my Dodge Ram 4.7 the next day.

Pros
  • Nice thing
Cons
  • No instructions

But it also sounds great at idle.

Not as loud as everyone thinks, or maybe I'm deaf. But it also has a great sound when idling. I always like to hear my exhaust. Update 2018: After I cut off some extra silencers or whatever that weren't part of the cat sensors, this silencer got insanely loud.

Pros
  • New
Cons
  • Legacy

I'm more than happy with my $80 double out single.

Tip: If you are new to exhaust DO NOT BUY THE SYSTEM, just buy this Super 10 muffler and then take it to the shop and install the pipes and tips. I'm happier with my $80 one-off at Super Double Outlet 10 than their $700 American Thunder system.

Pros
  • One Year Trial
Cons
  • Modern

Flat nasty sound on Hemi!

The silencer was delivered ahead of time and was in the original unopened packaging. Went from a Flowmaster Super 40 to this Super 10 on my 2014 Hemi Ram for a more aggressive sound and there and then something. Hitting the freeway flat out is like an indie car, more like a bark than a 40's.

Pros
  • practical item
Cons
  • no pistol

Devil Silencer :p

Gutty as hell, summons the lord of the underworld himself lol. great product, have used it with resonators and factory crampons, super great tone. really make my truck sound like a truck again. Previously there was a 3-chamber flow without resonators. It really brought my truck to life. NOISY! If you are building a cat back system this is a great silencer!

Pros
  • Nice to use
Cons
  • Only available in black

LOUD very loud in mufflers

This update I've had this muffler for less than a year, there is an odd rattling noise which I didn't realize was the muffler when it was first installed. I don't remember hearing it often, but I know I hear it every time I'm driving badly. I read some comments saying it wasn't noisy, believe me it is. I got it on v6 after a cat with no reonater and it's insanely loud

Pros
  • Great for me
Cons
  • Negative gift

Not as deep as 40

Good product of course it's the Flowmaster but people say it's better than 40 It's more of a tinny Honda sound I miss my 40 now that was the deep rumble of the Flowmaster I'm in love with, don't get me wrong, it sounds really good, I like it, it's just not an ad.

Pros
  • Pleasing
Cons
  • Vulgarity

Sounds great, just not as loud as I thought.

I bought this Super 10 Si/Do muffler to replace the Super 40 that was on my 2012 GMC 2500 6.0L when I bought it. I like the sound of the Super 40 but it's not loud enough. Got this guy in the mail today and welded it on with no problems. To my surprise, the noise wasn't much louder, but it sounded better. I had one like this on my last truck and I remember it made such a big difference, I wonder what's going on? Anyway, great fit and finish, great price just not as loud as I like!

Pros
  • Heavy Duty Construction
Cons
  • Upgrades

Not as aggressive as I expected.

I was looking for a slightly more aggressive sound from my current exhaust and muffler. My 5.3 liter Silverado truck originally had a "turbine" muffler. The previous assembly and processing was poor, it started to rust and had a hole. Decided to stick with this Flowmaster muffler. Hardly any difference in sound. It sounds better, but with the restrictions that trucks currently have, it limits the overall sound. I considered removing the cat but changed my mind. Overall I'm happy with the…

Pros
  • Certificate GOLS
Cons
  • Not satisfied with everything
