Magnaflow or Flowmaster
I've been looking at a cat-back exaust system for the future, just planing out. I've been looking at the Flowmaster and the Magnaflow. I like that Flowmaster lets you have two different heads, but i also want something thats going to give me more power and a nice sound. I'm also thinking about cost, but i guess i can sacrifice a little green for a nice system. thanks2006 Silverado Z71 - 97,000 - totaled, RIP

alright, i'll admit, I'm still a little green in the gills. Can you tell me what "dumped" means? And how loud is extremely loud?? Like piss off the neighbors loud when you get all over it as you leave the drive way, or wake up the neighborhood as soon as you turn the key??
I'm wanting a new system and 200 bones aint so bad BUT I'd rather not wear out my welcome around here.2004 Chevy Silverado 1500 LS

Magnaflow or Flowmaster : Pepsi or Coke?
I'm on my second Flowmaster. The first finally rusted thru, but it lasted 3 times longer than the OE muff. For the second one, I went 3" from the Y to the tip (at the bumper). A hi-flow Magnaflow cat and the "quietest" Flowmaster made. A littler rougher and louder than the original Flowmaster that had a section 2 3/4" pipe between the cat and muff. Changing that short section of pipe to 3" makes quite a difference. Just put on a 4" OD x 10" resonator tip and the wife is happy.
FYI: The Magnaflow cat failed at my last smog test, and it was barely out of warranty.Are we having fun, yet?

I just had a Magnaflow cat-back installed and I love it. I went with the single side exit. It sounds good but not too loud. Its just loud enough to be heard at idle but not so noticable at hwy speeds well untill you lay into it, then it opens up. Very noticable seat of the pants increase. Torque is the most noticable to me. Definitly two thumbs up from me.2009 Tahoe LT2; Graystone Metallic; 5.3L Vortec; 4x4; Loaded;
