Dynomax vs. Flowmaster, which one would you pic. I think I wanna go with dynomax, what you guys think? I'll be getting a high flow kitty with this cat-back system, y-pipe and eventually headers.

 

Flowmaster = loud and cheap
Dynomax = loud and more than flowmaster but better too

Id definitely spend the extra money on dynomax, cause then you see substantial return. Word.

 

Dynomax costs more? Where? Summit sells the WLK-17493 full cat-back for $150ish, isn't the Flowmaster catback almost $200? But I do agree; go with Dynomax. I installed the #17493 catback, and love it. Everyone in my town uses Flowmaster.

 

i prefer the flowmaster
nearly EVERYONE who hears my car mistakes it for a 350

 

i'm loving my flow 80 series....but yes, it is loud. very very loud.

 

Everyone I talk to who has a dynomax (all three of them) - love it.
Im sure flowmaster makes a good exhaust - better than OEM. But from what I know dynomax makes a better system.

 

I had a flowmaster and hated it , took it off and put a dynomax and LOVE IT !

Flowmasters sound better on V8s , just my opinion

 

yea, if you want load flowmasters your choice. but i have heard that it gets real obnoxious inside the car.

i have head only great things about dynomax.

myself, i am running 2.5" i-pipe into a hooker aero-chamber muffler and couldn't be happier. nice rumble at idle, and roars when ya gun it. and i can still hold a conversations with a girl in the car at night. i wanted something that sounded nice, but was tolerable at night or while talking. just comes down to picking one.

the benefit of dynomax of hooker is that it comes in a complete cat-back. i had mine custom done at a shop and just bought the muffler for about 75 from summit

Flowmaster sound cool at low rpms, but once you get on it... it gets ***** loud, kinda rough sounding. Dynomax is smooth at all RPMs and not annoying.
