Has anyone used a Walker Super Turbo muffler?

[turbovanman²]

Looking at muffler options to shut my exhaust up, I don't mind taking a hit in flow for the street driving portion as I don't need all the power on the street and I am getting a cutout for the track.

Right now, current setup is large body GM cat, Ultraflow muffler, small Magnaflow round muffler in the rear, 3" system with tail pipe in the stock location. Its not actually that bad right now but when I take out the cat for the cutout, its going to get loud and droney again, :( Barring the super turbo could be loud, I'll just use a generic 3 inch stock type muffler and that will shut it up for sure, lol.

50 mufflers and 100 cats isnt enuff already???? :p

the super turbo is awesome, not much louder than stock, but deeper. I would say its perfect for a street application

I have one in this vid on my 3.0 car

Walker = Dynomax. They are as quiet as performance mufflers get.

I have the stock 2.5" dp, and resonator (gutted cat) on my Spirit (2.5 8v with a stock Garrett). I made my own 2.5" mandrel tail pipe with a cheapie 2.5" turbo muffler in the stock location. Looks stock. Sounds stock. No droan.

Hey Simon, is your tailpipe past the bumper? I noticed a hugh difference in drone by extending the tailpipe beyond the bumper. It worked in both my van and my Dad's T&C wagon. We both use the 3" mufflers TU sells.

Interesting, we put one on my buddy's VW Fox years ago, it was pretty loud until we put a resonator tip on to soften the sound. That does sound nice and mellow but I do have a 3 speed 4 cylinder, :(

I know.

Yeah, I've tried different configs, this is the quietest by far.

on my r/t i got two straight thru mufflers on, one long one in the center of the car and one short one right before the tip its pretty quiet i have an electric cutout on mine as well but mine seems to run better with it closed, i know people say the more open the better but ive found the opposite. My mufflers look like big glaspacks but no ripples on the inside just tiny little holes i got them out of summit really cheap mine is also 3in

Unfortunetly, I have this big echo chamber behind me, lol. It seems they don't make many 3" versions so going 2.5" might be the ticket to shut it up, lol.

I have a 3" Super Turbo muffler on my Daytona. Drone is greatly reduced but it does get louder on cold days.

They also make a "Hemi" Super Turbo. I've never run one on a turbo car, but they made all the difference in the drone experienced in my family's muscle cars. We had the original exhaust replaced on our 71 GTX and specified Hemi Super Turbos. The shop installed regular Super Turbos, and the drone was horrible above 40mph. I took the car back and had Hemi Super Turbo mufflers installed. The muffler change made a HUGE difference.

Hmmmmmmmm, I'll try to find one. Thanks.

Simon,
I've used that Hemi Dynomax muffler for like 25 years. I don't like loud cars, never have for the street. My 70 Judge had a pair of them. At WOT the induction noise was probably louder than the exhaust. Had many comments from people asking what exhaust I had on that car. Even cops would inquire presumably so they could tell other gearheads what to put on their cars to quiet them down after giving them noise fix-it tickets (lol). My wife's car has one on at the moment. #17748 is the 2.5" #. 20" long case, 25.5 with ends. Reversible center in, side out. Regular 4.25X9.75" case size just longer... quieter. With a cat, the vehicle will be quiet.

I had a look but they only make a few models, so looks like I have to get a 2.5" unit, not really a big deal.

The 17748 comes up as a regular Super Turbo but I guess due to the case size they consider it a Hemi case?

Thanks guys. Going to try one of those and then maybe I can get rid of the rear muffler too, shave off a few lbs, bwahahahha.

Ok, local parts supplier has it, so if I have time, I'll put it on this week.

[turbovanman²]

Ok, so I put the 17748 on, that sucker is heavy, lol. I deleted the large body GM OEM cat and the Ultra Flo muffler, enlarged the 2.5" ends to slide over the 3" pipe, cut a section of pipe to fit the gap and installed with band clamps.

First impressions, it still has a throaty idle but you rev it up and it seems quiet, on the road, certain throttle angles its almost dead quiet, others, some drone. Throttle response, off boost power, spool and turbo hit are all dramatically improved, I noticed it almost immediately. Now the important part, around town, good, at 100 km/h a tad, not enough to worry about, 105-120 km/h, it drones a bit, 125+, quiet. As I log more miles, I'll see if I can live with it or not, if not, running out of idea's, :(

[glhs0426]

If you would have left the cat, do you think it would be quiet?

[ScottD]

I have a super turbo on my turismo.

2.25 full exhaust w no cat but I do have a resonator where the orig resonator was.

Sounds good at wot but quiet at cruising speeds.

[Directconnection]

I put a super turbo on my old VNT years ago with cat delete, and I could barely tell the difference over the stock muffler. It wasn't a ROUND muffler, mind you.... it was the ovalish shape, and that will give you more sound dampening with that design over the round. So if the hemi one you're using isn't quite quiet enough, then try the oval wide one like I had....?

[Force Fed Mopar]

Where do you have the muffler located Simon?

[turbovanman²]

I replied yesterday but it didn't come thru? Anyhow, yeah, It would be dead quiet with a cat but I have no more room, lol, I need the space where the cat would go to run the cutout and this muffler is long, space is limited, sigh. Guess I'll live with it or put a stock truck muffler on.

Yeah, its a 3inch setup, flows well, plus the echo chamber behind me.

This is the large oval body unit, I could have gone with the 14" unit but I knew I'd have issues if I did.

Where the stock one goes, in front of the gas tank, I could move it forward 12 inch's but probably wouldn't do much plus then I can't put the cutout in when I get it. I have a mid size Magnaflow round muffler at the rear right before the tailpipe. I have redone the whole system in stainless so ignore that aluminized crap, lol.

This is an old pic but you get the picture, same location.

Need some heat insulation around that tire :p

I was gonna say maybe put the muffler at the rear, but you have one there already :) I dunno, when you had it exiting out the back, did it extend past the bumper, and did you have a turn-down or straight out? What if you just ran one muffler at the very back? Maybe all those muffler combos are doing funny things w/ the sound waves.

Also, do you have a full interior still? I can never remember lol. I know you were talking about adding sound insulation soon.

[turbovanman²]

No rear muffler its bad, just a rear muffler, its bad, 2 mufflers, almost liveable, lol.

I have a full interior but yeah, I need to add some real sound insulation, but keep finding other speed things to spend money on, lol.

No wonder why your van "weighs" so much.... you have little, to no, rot!

LOL, its starting though, both 1/4's, :(

[Vader85]

Yes but they rust from the inside out......they do offer a nice sound though!
