Flowmaster American thunder #17233

Anyone got any sound clips? The links in the sticky section do not work. And YouTube is a useless land of advertisement anymore..

Thanks

Get an adblocker, there's a video link here:

It's going to sound like an 80 series Flowmaster on an SBC.

PM me your phone number and I'll shoot you a video when I get home today.
I bought it a year or two ago. There was a lot of lead time (like 5-6 weeks).

Re: Flowmaster American thunder #17233

I recently swapped my Flowmaster for a Flowtech Afterburner. I will be putting the Flowmaster back on next week. Hard to beat that Flowmaster sound in my opinion. The only muffler I liked better out there is Borla. I don't want to spend $300 on a muffler.

Nah cant agree with you there...If they didn't sound good they wouldn't have sold millions and counting every day. . Ive ran almost every transverse muffler out there on these cars. Borla is best, Flowmaster #2. If you want quiet get a Magnaflow.

By that logic cheap generic fart cannon mufflers must sound amazing millions have sold and more every day from random Chinese drop shippers on ebay. Flowmaster has a loyal following because back when cherry bombs were the only option they came along with something marginally better. But they use low quality materials and make a low end exhaust that sounds like ****. Just about the only thing you can hope to do is add a resonator or two so it sounds better than a tin can megaphone hanging off the back of your car.

14888 borla catback. Sound good better materials about $550 more expensive than flowmaster. Borla makes good stuff for just about every car

Re: Flowmaster American thunder #17233

It's a matter of opinion, I personally think they're obnoxious.

At idle they're loud and sound OK, but that gets old fast. A friend of mine has one on his Camaro with a low compression 350 truck engine in it and with it parked 30' away and me standing next to my car I can't hear my car at idle over his (my car has a big cam, headers and a straight-through Dynamax Ultraflow welded on it). At part throttle, they drone badly in the car and are pretty bad WRT to performance, worse than a stock style muffler or an old school turbo muffler.

But there are people that just want that sound... The friend with the camaro is fine with the car being a high 14/low 15 second car and sounding like he wants it.
