Thread: flowmaster mufflers...worth it?

Tweet

I don,t know who makes these but they are called Big Daddys and they are built like cherry bombs but have their own sound. Don,t mean to offend anyone but flowmasters sound sick. I guess it,s because everyone has them and i have always liked to be different, just can,t stand to be just part of the crowd.

Had flowmasters on my 34 (sb) and they were decent. But they were beginning to get rusty so I replaced with a pair of Smithy's. Much louder, but if you go fast enough, you won't hear them.

I also have a set of Smithy's on my big block Olds, and that is were they really sound great. Nothing sounds as good as a big block running in-line glass paks.

...I had a Flowmaster Cat Back on my '94 Firebird LT1 & I loved the sound. But I did read {on camaroz28.com } that they were not the best flowing. I don't remember which ones flowed best. But I do remember that Flowmaster makes a bunch of different mufflers that have different sounds. If I were you I'd get their catalog or go to their web site & check out the different styles available.... Bill

JC Whittney has side pipes, up to 72" I believe. They are just a long glasspack, and sound awesome. Great flow. Had some on the ol' lady's 86 Dodge diplomat ( former cop car ) with a 318. The side shields on these has realy cheezy crummy chrome though. Looks great until it gets wet a couple times then it's time to grab the high-temp flat white rattle can and cover them over.

As for Dynomax, I have a set of their big glass pack turbos, with offset inlet/outlet. Never really liked them.

Try BORLA stainless headers & flomasters & you will not even beleive the sound.

Are you aware of "Jones Mufflers" which are an exact copy of the Flowmaster. B & B auto parts in the Seattle area sell them for 1/2 the price of the real thing and they sound great behind my GM 350.

Very true!!

Well here is my 2 cents worth of info.

I dont think they (FM's) sound tinny at all. In fact, just the opposite. In addition, different diameter pipes, different series flowmasters, and different configurations (dumped at the axle, straight out the back, 45 degree out, etc...) are all gonna sound different. AND, it'll sound different depending on where you stand around the car (back, side, inside, etc...) So to say flowmasters sound like this or that is the most general of statements.

As far as flow...well, one of the rags did a test a few years back on a particular series FM and they did flow poorly in comparison to the other brands. Do they all flow crappy? who knows... We'll find out when someone conducts a test or when more people provide some ET numbers that we can compare (hint hint people).

So really, do whatever the heck you want. Hell, go to U-tube or one of them places and search around. Plenty of guys (who's wive's and girlfriends think they are nuts) post videos of their exhaust notes.

Decisions, decisions....

I have flowmasters on my 62 impala with a full length 2 1/4 exhaust system. The sound is great until you get on it then it has that old time glass pack "rattle" which bugs me. I don't have an H pipe which might settle it down a little but with the X frame exhaust it is kind of hard to do. I had a set of 40s on my mustang and it sounded great. Side pipes on the wifes mustang sounds pretty good too.
