Flowmaster vs. MagnaFlow

[LiloleV6bird]

my flowmaster with no cat sounds pretty good. i dont have headers. sounds like a 4.3l s10 with no cats a flowmaster with turndowns. great sound to me.

I have a magna muffler with my stock pipes and it sounds good. But once I put in my mid-tube pacesetter with a catco high flow cat, man I never thought my car would rumble so much.

This guy that owns a muffler shop told me that flowmasters on a V6 doesn't sound that good. He told me to go with a borla or magnaflow so I went with magnaflow.

I've also heard a few V6 cars with a flowmaster and compared to magna I think you should go with MAGNA.

I vote Flowmaster American Thunder

hmmmmm, if I wanted to change my muffler to a flowmaster american thunder will I be able to use my catback pipes that connects to the cat to the muffler?

I just got the Flowmaster American Thunder 80 with the resonator installed last week, and I really like the sound of it, doesn't sound ricey at all, even at high rpms. And the sound inside the car is still at a reasonnable level. Performance wise I don't really know if it changed much, I only had my Firebird for 10 days, so I'm still not use to her. It is not too bad for a car, but after my Yamaha R1 (crotch rocket), I feel like Im back in the slow world...lol...cars are slow unless you get a $100000 Porsche Turbo or a Ferrari... Well, at least I may be able to avoid a few speeding tickets now, and no more crazy top speed (189mph on the freeway here, try to beat that with a car;).

i have the flows, and my only problem was my dumb a s s installing the muffler wrong so everytime i go over bumps it bangs against the body in the back. it really sucks. i love the sound of the flows. i have not heard to sound of any other one yet. if you get the flows make sure the muffler is angled right so it wont bounce around.
but i want to say that flowmaster is a company souly for exhaust. they only produce exhaust elements. IMO i think this is better because mt research is backed into their products, its worth buying. they are not a multipule product producer. only exhuast. it think they are great. but my all time favorite would be BORLA.

my friend did 196 on his R1 down the highway....

[sedoriku]

KidCamaro, sorry to dissapoint you, but your friend is a liar...the speedometer on the R1 won't go any further than 189mph. It is a digital one and it goes up to 189mph, not more. But well, it is a common thing amongst rider to lie about their top speed, but in that case your friend got owned!!!

I have the Flowmaster American Thunder 80-series catback, system 4 a 3.8L...lemme' tell ya' a lil' bit 'bout what sux. There's a pretty crappy "drone" on the highway @ times. Although, w/ 2 10" Kicker Competitions...it's not a huge prob. 4 me. Sometimes (an' I'm not totally positive this is the exhaust) it'll sound 2 me like the pulses R tryin' 2 cancel each other out, @ a certain RPM...sounds dreadful, 'til U whack the gas. It tends 2 SCREAM Ferrari-Style, in the upper RPM's(which w/ an A4, U don' get 2 enjoy 4 very long), but it's somewhat "tame" soundin', down low. I guess some people like it this way. *SHRUG* I noticed a pretty good increase in power after initial install...an' got a HONEY O' a deal on the whole system. But BEWARE...it's barely been on, an' recieved SEVERAL coats O' exhaust paint B4 install...already got a coupla' rust issues, as it's NOT Stainless Steel (pay another $400 or so, if U want that). But I do have it mistaken 4 a V8, quite frequently.

[IMTHEPUNISHER]

P.S. I've got a brand-new factory cat...this could B part O' my "problem"...oh yeah, an' make sure it get it all welded-up, after install, as it will rattle on everythin' it can otherwise.

I have flowmaster 2.5" system for the v6 and there is definitely ZERO popping.

[Kidcamaro98]

sedoriku...

considering the R1 has custom gages whats hard not to believe about it?

Yeah that's no joke. I got custom 2.5" dual exhaust and had it installed by a mechanic I know for a little over $200. Sounds as good or better than any flowmaster or anything else I've heard. It also leaves funds for more mods that I'm looking to do [img]smile.gif[/img]
