The Great Flowmaster Super44 drone experiment of 2012.

Ok, started cutting stuff up and welding a little.

I have a feeling I will eventually be going to a different brand of muffler, and already have a guy with a newer mustang that wants to buy these off of me, but first, I want to experiment with these and see if I can successfully lose the drone.

So first step...cut the downturns off and make them exit straight out the back of the car right at the muffler.

I will report back and let you all know if I notice any difference.

I have several other steps I plan on trying out before I am done. If I get rid of the drone at any of these earlier steps, I will stop and re-fab them up in whatever configuration I am at at that point.

 

I guess, technically, this is step 2. Step 1 was adding an H-pipe which only moved the drone to different rpm levels.

 

Ended up with this, and the car is MUCH quieter, and drone has improved, but is still very loud and annoying. The drone is loud, but the engine/exhaust sound is very quiet.

I have concluded that the location of the actual muffler being right below the seating area is where the drone comes from.

At this point, the car is so quiet, I may as well just go with a quiet muffler, since I have rendered the shock effect of the Super44s aggressive volume and sound worthless.

 

Drone is what you get with Flowmasters. The Chevy guys love it. Makes it sound faster.

 

Sleeper Mav!

"Doesn't look like a hot rod... doesn't sound like a hot rod... Holy Benji Batman! Where'd he go???"

 

I'm torn between putting a quiet exhaust on mine to hear the 3x2's again, but love the raspy sound of the Turbo Tubes I have on it now.

 

I like loud and raspy, but I don't want it to sound like the u-joints or harmonic balancer are out inside my car.

 

I keep reading where people are ragging on glasspacks, but most folks seem to like the sound of mine.

1 5/8 longtubes and glasspacks, dual 2 inch pipe, gotta go bigger.

Going from manifolds to longtubes actually made the car much quieter if you drive like a grown up, louder if you don't.

No drone, cruising at 55mph is pretty quiet, 70mph isn't loud to anyone but my wife.

 

I had glasspacks on before, and liked the sound. I really liked my sidepipes with LONG glasspacks.

Check these out good and loud no resonance

 

Cool! Thanks for the link! Looks a bit like glasspacks, but I guess without the fiberglass?

 

Boss man has some on his chevelle they sound good without the classic glasspack sound

 

Those are what I have on mine, they were originally sold under the name "Turbo Tubes". Mine are 2-1/2" dia x 18" long.

 

Right, no fiberglass, they're just a perforated pipe surrounded by a larger pipe that's crimped to form chambers around the perforated pipe. They'll make em to whatever length you want.

 

baddad, how do you have yours mounted? Where do your pipes exit? No drone, really???

Are they still mounted straight exit at the axle like in your photobucket pics?

I should be able to buy a pair of 16" ones and stab them right in to where my flows currently are.
