    Big Block muffler choice

    If I remember correct I’m running Dynomax ultra flow 17233. Before I put tail pipes on, it would shake everything around. I’m running 3” with x pipe all the way out on my big block Demon. Fairly docile at idle, but when you squeeze the skinny pedal it opens up. I will say interior noise isn’t...

    Exhaust Band Clamps

    Rusty what you have listed should work fine for the OD pipe into the ID pipe. I used them at the muffler on my Demon and they seal and work good.

    Lets see your exhaust systems with relocated leaf spring

    Yes 2.5” would be easier. But I’m stubborn sometimes and with the 440 wanted to let it breath. It’s pretty docile til you smack the skinny pedal. Dynomax ultra flows really open up. I had dumps but it would rattle anything around at a stop light and didn’t want to deal with the law. The...

    Lets see your exhaust systems with relocated leaf spring

    See if these help. Best I can do with wheels on. Very snug on passenger side front corner of fuel tank but it clears and don’t hit.

    Lets see your exhaust systems with relocated leaf spring

    I can't get pictures til this week end. On my Demon I ran 3" from the headers back. Its mini tubbed, springs moved to frame rails and stock gas tank. The only piece I could use on the TTI tail pipes was up over the axle and the passenger side the down leg going to the back had to be modified. I...

    tti Header Hitting Torsion Bar

    Is the front of the car on jack stands? If so try putting weight on wheels and check. Depending on where you have the stands, if you do, there is some flex in the body and that may change things.

    tailpipe question

    Personally I'd wait til after I moved the springs. If you are doing the relocation to the frame rails, I have my doubts as to the tail pipes working. The drivers side maybe. Passenger highly unlikely. Here's a picture of my Demon with springs moved in to frame and stock gas tank. I believe the...

    Sudden Change in Engine/Exhuast Tone?

    Venturing a guess, 20 yr old glass packs, I'd say the packing is going or gone.

    This is the MRL built 440 in my 71 Demon. 9.88-1, .030 over with Edelbrock RPM heads, RPM intake. Lunati solid roller 60331 237/243 @.050 .566/.578 lift. TTI headers into TTI 3" x pipe thru Dynomax Ultra Flow 3" in and out. No tailpipes yet but will have once on the road. Still needs some fine...

    3" muffler suggestions

    I know this isn't a direct answer to your question. On my Demon I'm running TTIs and will be running 3" with the ultra flows. It has springs moved to frames with mini tub. I plan to have tail pipes made that go over axle to the outside of springs and to run 16" race mufflers in the tail pipes as...

    Adding Catalytic Convertors to the Old Girl...

    I would think its not a good idea. If the engine has had anything done to it where it is beyond stock, I would think that the cats would run way hot,Even if it's at a stock level. Gotta remember they are there to help "burn off" residual fuel. They may even get hot enough to cause a fire. One of...

    Any tricks out there to remove burned oil from exhaust system?

    If they're not ceramic coated, maybe try oven cleaner on a spot.

    NOS 340 EXHAUST manifold

    My guess at best is that they still would have been manufacturing service parts into 78. The cars were only 5 or 6 years old at that point. But as I stated that's just a guess.

    De-trickulatatin a header coating conundrum.

    My .02 cents was the surface temp was too hot. This is from their directions. Ideal application temperatures of air & substrate to be coated are 50-82°F (15-28°C). KBS Xtreme Temperature Coating may be applied by conventional or HVLP spray, airless spray, brush or roller. Do not apply KBS...

    Straight Through Mufflers

    How about the flowmaster pro series? They're pricey but the clips I've heard they sound pretty good. May use them myself when I get there. http://m.youtube.com/watch?v=Zp9Rj6uzFXg

    Sorry, didn't know you had floor shift. Was looking at notes for column shift.

    440 2" TTI Fitment Issues

    I have a set also. Have not installed them. (Still a work in progress). The TTI footnotes state they will not work with the factory shift linkage. I plan on using the Ididit cable conversion for the shifter. By the way I am retaining the column shift. Cazbah beat me to it.

    TTI 440-200 Shift Linkage Mods

    Hello, I did a search but can't find a specific answer so here goes. I am looking for info from people running an RB (440) with the TTI 440-200 headers (2" primary tubes). I am looking at a set for my 71 Demon with the 440 and was wondering what shift linkage mods are required to keep the column...

    collector hangs low

    Don't know if you've seen this, but it may or may not help. This is from TTI's website. Gives measurements of where engine should be sitting in relation to structural components. http://www.ttiexhaust.com/PDF/II_TTI440-200.pdf

    440 cast manifold bolt question

    The longer ones that are recessed into the Janelle will need a spacer if you are using bolts. If using studs you can check here for reproduction hardware. Hope it helps.http://chucker54.stores.yahoo.net/oemexmastnu.html

    Whats the spitting!?

    My vote is the baffles and or inner wrap of the muffler is loose and floating or vibrating and blocking the exhaust flow.
