Anybody running a Flowmaster??

[Hodag]

I have a 40 series Flowmaster on my 74' V8Pig. I love the sound coming out of the tailpipe, however I am tired of the resonance inside the cab. On a new Flowmaster at a buddies house I saw a heatshield type thingy hoseclamped to the muffler body. Are these available from Flowmaster? Or is it a homemade fix? It looks pretty trick, and I'd like to know if it would help the resonating in my pig. Thanks in advance, Hodag

From my experience with that you will not loose much noise with a shield. Problem I think is in the choice of 40 series Flowmasters. As I reall the lower the number the bigger the noise. I got dual Flowmasters on my truck--50 or 60 series I think--and they are plenty loud enough for me. You might try some insulation under the floor mats.

I believe the 70 series is the quietest.

Flowmaster

Hey Eric I have a Flowmaster on the 60. Now that the exhaust goes through it instead of everywhere else it is a little loud too. I had Flowmasters on a ford 390 and it was very cool as long as your weren't idling or going 1800 rpm. It resonated really bad.

That's why I switched to Magnaflows a long time ago.

SAY WHAT?

I SAID, THAT'S WHY I SWITCHED TO MAGNAFLOWS A LONG TIME AGO

SWITCHED TO SAGGING HOSE?

OH, NEVERMIND!

Dude, you need a bigger amp...

Where does your muffler sit, and where does the exhaust exit?. If somehow you squezed that muffler in the stock location, that would explain it.

second on that magnaflow comment. I like mine under my fj55, even though it is the only piece of chrome on the entire vehicle.

Sounds like a homebrew heatshield to me. I can't see how it could change the noise level. I run a single 40 series on my 2F and it's definately loud. But it's not a daily driver and I like the sound so it's staying. I have a buddy with a 72 bronco with a 302, headers , and dual 70 series flowmasters. Same burly sound, but nowhere near as loud as 40 series. Still loud though. Dual 3 inch 40 series behind a big block sound really, really cool.
