Muffler decision Dynomax Super Turbo, Ultraflow, or stainless works

Trying to decide between these 4

Dynomax Super Turbo
Dynomax Performance 17769 - Dynomax Super Turbo Mufflers - Overview - SummitRacing.com

Dynomax Ultra Flow
Dynomax Performance 17233 - Dynomax Ultra Flo Welded Mufflers - Overview - SummitRacing.com

Stainless works
Stainless Works - Performance Exhausts and Headers

Borla XS
I've always been a fan of borla but I have a feeling they will be just as loud as magnaflow

On the stainless works I'm assuming the non chambered straight thru one is the one to go with.

What I'm looking for specifically is something quieter than my current Magnaflow (I didnt choose it thats what ZZP happened to use I've always had intentions of scraping it). I'm looking for the best flow with quiet sound, but I dont want to give up any hp to do it. I'm leaning towards something stainless and straight thru since I want good power and I drive in winter so I dont want it to rusting to pieces.

Can't decide between them but im sure ANY of them would be better than the crappy magnaflow thats on now and has apparently blown out, its loud and ricey as hell, I'm quite embarrassed in public to drive it, it sounds that terrible.

I'm having my stainless works put on tomorrow. I'll post some videos to help you make your decision!

I vote SW. Ultra flo is straight through so it'll sound like any straight through muffler...loud and a lot of drone. Super Turbo will eventually blow the fiberglass packing out and get real buzzy. SW is your best bet.

I'm getting the turbo style (chambered)... The Ultra Flo is only straight through I think. For chambered dynomax you'll have to get the Super Turbo

yeah could be a leak. sounds like air flowing through it. i would think a leak would be a little higher pitch. depends where it is at though

No leak...it's the way turbo mufflers sound with no cat on these cars, not much tone, just a little rasp/buzz and air rushing out...It's still a little raspy..I've tried all catless setups and I have come to the conclusion that if you want no rasp, you need to have a cat....

It has a Clear Image Automotive header, 3" downpipe, 2.5" Mandrel Exhaust Systems cat back with 18" Magnaflow Resonator and the 2.5" Stainless Works turbo chambered muffler...

here it is installed:


The hanger method is a little primitive, but you can't see it unless you're under the car and it's rock solid. It won't rip off of the muffler case like the way MES puts the hanger on.
