    Dynomax Ultraflow mufflers..

    I have 3 1/2" aerochambers on my 540 Demon going into dumps, H pipe. Sounds OK but haven't really been able to wind the motor up yet. On the 46 I used 3" X-pipe, 8" long cherry bombs, then 3" flow 40's. IMO it sounds great and no tunny sound after the bombs went on. Tried that with the 3...

    Muffler sound

    I have 3" TTI and run 3" all the way through an X pipe, then into 8" long cherrybombs, then Flowmaster 40's into dumps. I think it sounds perfect. The cherry bombs really cut down on the drone and mellowed out the sound.

    Exhaust exit location

    I like my dumps. They point at the rear tire from in front of the axle. Do not point in front of the tire incase something lets loose inside the motor.

    Question for those who like Flowmasters...

    I have 3" flow 40's on my 416 fish into dumps. I didn't like the raspyness and had the shop add a 8" (called 14" cause of the ends) 3" cherry bombs before the flows and it sounds perfect to me.

    X & H pipe vs straight dual exhaust

    I had similar results going from TTI headers (open) to a 3" X-pipe into 3" flow 40's and then dumps. Even with the added weight the 1/8 ET went from 7.25 to 7.20. I later added 8" long cherrybombs in front of the flows to take away the raspy sound. I love the way that exhaust system sounds with...

    TTI vs Hedman which one?

    I am building an Indy headed RB to put in my 71 drag Demon. The only headers that seem that they will work are the hedman 75161. Problem is hedman tech support hasn't returned my inquiry on if those will actually work on the engine / car. My inner fenders are long gone.

    Stabilizing headers to the engine?

    My ex has header bolts and hangars back by the mufflers before the dumps. Works OK.

    size & "H-pipe"

    I am not trying to argue with OMM but my TTI step into 3" collectors, Jegs or Summit (cannot remember) X pipe kit, 3" x 8" cherrybombs before flowmaster 40's into dumps at the axle picked up ET and speed over open collectors and to me sound perfect. 3" all the way.

    Need to make final decision on mufflers..

    I have 3" flow 40's into dumps and they were kinda raspy. I added 8" long 3" cherrybombs in front of the flowmasters and the sound mellowed out nicely. I really like the way the car sounds now. Kinda loud but it is a hotrod after all.

    **Summit Universal X Pipe with TTI Headers**

    I used that X pipe system on my car with the 3" TTIs. No pics but it looks just like the TTI X pipe system. I also have dumps like you will be doing right off the mufflers before the rear axle. The mufflers I used were flow 40s with a 8" long cherry bomb in front of them. The sound is...

    New TTI's rusting?????

    Get a big sheet of cardboard and lay it on the ground in your garage under the headers like TTI says to do. You have moisture coming up through the slab (or gravel surface) and that is where the rust is coming from.

    Open headers vs any muffled system

    When I first put the stroker into the non-carpet fish I hated the niose. Car ran 7.25 open header. ordered a generic 3" X-pipe and a set of flow 40's and had them put on. Car sounded a lot better but still had raspynedd. Ran 7.20 that way. Had a pair of 8" long 3" cherrybombs between the...

    Suggestions for muscle car sound muffler without drone

    I added a 8" long cherrybomb in front of the dual 3" flow 40's and it greatly reduced the raspyness of the sound. My exhaust is pointed down and out at the rear end. Sounds like 4 harleys coming in as I downshift going into a bar parking lot. Pisses off the bikers cause they all have to look...

    TTi ceramic coating warranty

    They also advise you to put some cardboard under your car when in the garage/shop so the moisture from the concrete doesn't rust them up. I also "oil leaked" onto mine from my breather hose.

    X pipe vs H pipe

    I had real good results with putting a 3" generic Jegs X system on my 416 with flow 40s dumping at the rear axle. Was a tad raspy and adding 8" long cherrybombs before the flows smoothed it out. ET dropped by about .15 despite the weight. TTI 1/78 stepped headers. Basically copied the TTI...

    When to go bigger?????

    Right and for my TTIs that was 3". I gained over a 10th over an open collector with the 8" extension when I put on 3" X-pipe and flowmaster 40s with a 3" x 8" cherrybomb in front of them.

    When to go bigger?????

    I used 3" on my 416. Fit OK and works well judging from the time slips.

    Dougs headers or TTI step headers?

    You got lucky after bashing the tube to worthlessness. I have a slight rub on my left side torsion bar but I also have solid mounts so I caould just shim the motor to get the best clearance. we'll find out soon how well they fit another A body when I swap the motor and headers into a 71 Demon...

    header size for stroked small block?

    My 500 HP 416 has the 1 7/8 TTIs with 3" collectors. Automatic if that matters. I had the exhaust shop hook up a Jegs generic 3" X pipe into 3" flowmaster 40s. The car picked up over a 10th over open headers with the X pipe and mufflers. I then added 8" x 3" cherrybombs in front of the flows...

    Just got the 3" exhaust system hooked up

    The car had some resonance "bite" at certain RPMs so I had 3" x 8" cherrybombs added right before the flowmaster 40s. The bombs act like resonators and take some of the raspy sound out before the flows get to it. Now the car has 3 distinct sounds. At the point where the engine is just...

    "H" or "X" Pipe advice Please

    Thanks for the writeup OldMan Mopar. I was wondering how that strange setup you have on the Duster sounded. Like I posted already my car went a lot quicker with the X and mufflers. It sounds pretty good from inside but could be better as I have no insulation or carpet or back seats yet. Will...

    "H" or "X" Pipe advice Please

    My muffler guy didn't do the heat thing cause I brought the car down with the headers and collector extension already on and the Jegs X pipe kit in pieces. he put the X a little after the frame member kinda like the TTI premade X pipe setup. We left some room in a straight section before the...

    Ceramic Headers 67-69 Barracuda 340

    My local muffler shop was able to duplicate the TTI X pipe system using the components from my Jegs $100 X pipe kit. I put on flowmaster 40s and dump right after the mufflers down and outward toward the ground next to the rear tires. Car sounds pretty good but I may add a 12" section of...

    SB TTIs

    Those are nice. I just put a set of them on my 68 fish. 3" all the way from the collectors through the X pipe to the flowmaster 40s. A tad loud and may try to get the muffler shop to put a set of 3" x 12" Dynomax bullets on the straight sections of the exhaust between the collectors and the...

    Just got the 3" exhaust system hooked up

    New heraders came with the engine. I would have to measure the tubes. The tubes are pretty big and the collector is 3". I had the muffler guy make sure that there was room to put in another muffler if needed which I may use to put a pair of 3" x 4" dia x 12" long Dynomax "cherrybombs" between...

    TTIs installed tonight!!

    Take a look at TTIs wwebsite to see how their 3" X pipe looks. I had a local shop copy the idea using a Jegs $100 X pipe setup. With flowmaster 40s the car did not slow down a bit.

    Just got the 3" exhaust system hooked up

    68 fish, 416, TTI headers. used a Jegs generic 3" X-pipe and a set of 3" flowmaster 40s. Mufflers to the rear like the TTI X pipe system. Dump on the inside of the rear tires. Sounds pretty good. The car did not lose any speed on top and the ET was actually a tad quicker. Was not able to...

    Ceramic Headers 67-69 Barracuda 340

    My TTIs got in OK but I have manual steering. I use the 90 degree adapter for the oil filter and a Mopar mini starter. One thing for sure is the TTIs are tight. Had to cut out the old headers or take apart the steering bars. The TTI with the removable #7 tube went in ok and with some...

    Ceramic Headers 67-69 Barracuda 340

    And if you look at the rear of the TTI X-pipe it also angles so you can ONLY use dynomax mufflers. At least their literature says the system is made to fit Dynomax mufflers. I will find out soon if I can salvage the Jegs $100 X pipe kit by having a local shop install it or have to bite the...
