Ground clearance

Thinking about changing my mufflers to get a better sound. For those of you who have mufflers under the seat area and can make it over most speed bumps, how much ground clearance do you have under your mufflers?

Rob,

My car's in the shop at the moment so I can't give an exact measurement, but I'd imagine it's around 3 inches. I've got a flowmaster and it's tucked up about as tight as you can get it. I've only bottomed out on a couple of "monster" speed bumps, and when there is a lot of undulation in the road, coupled with bad patch jobs (a.k.a. Memorial). It is the lowest point on the car. Here are some pics of my setup.

Good luck with that, Rob. I removed my front stock muffler to increase ground clearance. :)

...3-1/2" ground clearance at the muffler, Rob

Here's the overall system....

Glad I didn't have to straddle any road kill while driving your car, Graham. My 15yo daughter did in my car (car coming the other way). We didn't clear the dead groundhog. She thought it was gross. :)

What about those armadillos, Rob?!

Don't have to worry about the armadillos Carl... My front valance will clear them long before they get to the mufflers ;)

For anyone familiar with armadillos especially on the I-10 bayeau bridge between Texas and Louisiana... Why did the chicken cross the road? To prove to the armadillo it could be done!

My radiator hung down just above the splutter on my old car, but I address a piece of 1 1/2" angle iron as a cross brace and PROTECTOR. I think my mufflers were at 4", but the current is low also. I have scuffed the front cover on the parking curbs. Guess I need "Curb Finders and Dummy teardrop fog lights" also. ;-)

Rob, currently the ground clearance on my car is about 30".........................got the rear suspension apart for lubrication.
I'm quite sure the clearance is between 3 1/2- 4" and I've scuffed several monster parking lot speed bumps that have left marks on the mufflers. I'll measure for sure when the car is back on the ground.
I have two Thrush mufflers with heat shield spaced about 1" from the floor and a home built resonator in place of the original muffler.

Round here the chicken crossed the road to prove to the Possum it could be done.

You Texans have let that varmit, Armadillo, make it all the way to Florida!

Armadillo -- "Possum on the Half-Shell" :-)

They make great stringed instruments:

I have 4" with my spintechs but I don't like the sound. They are only 2.25" thick and are about an inch from the floor board. Thinking if new mufflers are 4.5" thick, I'll probably lose about 1.5" of clearance which would put ground clearance at only 2.5". Maybe my car is sitting lower than most?

Don't know if you could get this Dynamax muffler to work...3.25" thick but only a 2" inlet.....at least the sound is better than most!

Some Walker Universal mufflers (# 17602, 17603 & 17604) with the same body dimensions, but with 2" inlet/outlet....

Am thinking I want 2 1/2 dropping to 2 1/4" where they snake through my IRS. That's what I had in Townsend. I lost a lot of HP and torque when I changed to current set-up (2 1/4" to 2"). If I'm going to change the exhaust, I might as well get some of that back.

Might as well go to chambered exhaust like Dan Masters setup.

That's why I went to the exhaust in the rockers. No ground clearance issues from the exhaust and no power loss from the full length headers.

I started out with chambered exhaust. LOVED the sound! Way too loud for me though. Even with 54" on each side. I was setting off car alarms at work all over the place which wasn't good (we have parking garages so the sound echoes). I sold that exhaust to a member here. I even had the full exhaust ceramic coated to the back of the chambered tubes. I should have kept it to put back on after I retire, but needed the cash.

The spintechs are great for clearance, but don't have the bass sounds of other mufflers. I'm hoping a regular Dynomax or Magnaflow will be a good compromise without making it a pain to drive around town. Every parking lot around here has a bunch of speed bumps.

And Ted Lathrop & Steve Carrick. Those things sound awesome. Quite heavy, though.

My car is louder than is used to be. I removed the center muffler for ground clearance & I have been giving the rear one a workout for 15+ years. I now understand Rob's comment about parking garages. I parked in one a month ago in Asheville, NC. My MG roared like a loin coming out of there! A mini-van pulled over to let me by & the passenger stuck his arm out the window with a thumbs up. It sounded like my 350 Camaro with burned out Cherry Bomb header mufflers. Yeehaw! ;)

Thrush Turbo is another option, made by Walker and available in the same dimensions as the Dynomax linked to above... I've run them since I built my car. Back then, they were about $20 each. Probably somewhat louder because Thrush doesn't include fiberglass packing. I've got them set into pockets under the seats, to afford a little extra clearance. I just measured 5" from rolled flange to garage floor. (Distance from the trim/seam on the front fenders to floor is 25".)

Rob:
Just measured my clearance tonight and have 4 1/4" from the bottom of the mufflers to the garage floor. The measurement from the floor to the bottom of the front fender (centre of wheels) is 23 3/4". and the rear is 23 1/2".
