    About 4 years ago Mopar Action did a Bold Beeper series on a Road Runner project car.

    496 Barton motor, TTI 3 Inch pipes with an H-Pipe.
    Made 435 hp at the tires.
    They disconnected the center section at the headers and threw in the new TTI Nascar style X-Pipe and guess what happened??

    HP up 24 to 459 and picked up 16ft/lbs of torque with a simple bolt in swap.

    Read it and weep:

    Rumblefish please dont start the whole "whats a streetcar?" deal i thought you might have seen where that one leads before?

    what is streetable is up to the owner,i know there is lots of 7-8-9second cars driven on the street that are more reliable than the average 10-11sec bracket car. i wouldnt mind driving a 7sec streetcar to work everyday if i ever build one and just have a wallet thick enough to pay for it.. i have even seen a dragster driving thru the drive thru at McD.

    Exit in the rear 'behind the tires'

    You could have them dump just bhind the tire but outward to the sides, but during idle time you may get the stink in your clothes.

    ANY pin holes or floor opening with before axle dumping pipes...and you will have the stink after driving a mere 5 minutes....

    Im staying out of the bicker party, but fwiw the X/H are supposed to equalize the pulses and pick up mid range torque.
    How much could be lil or substantial.

    I don't run one myself, I don't to have to cut it out when trans woes do or do not arise, an I don't want another leak point with having extra collectors to make them easlier removable.

    I LIKED how my old sixpack sounded with side exit exhaust. I grew up in the country, and though we had a Farmall, I do know EXACTLY what a Deere sounds like, and side exhaust V8s do not. An yeah. It's your opinion

    You obviously didn't spend any time in my car "in the day." When I first bought it, it had some obnoxiously loud Cycle packs on it, but with the windows up, it was hardly any louder than a stock rear exhaust--something I'd heard a lot of, since I just got rid of a 69 383 RR with headers and otherwise stock exhaust.

    After I put the factory stock type HP mufflers on it, it became even quieter. Most of the time I drove that car, it had the driver's window down. In this case, it's NOT your opinion. You're simply mistaken

    Thanks to a house fire, one of the very few photos of the old girl. About '73 or '74. Had a 340!! in it then

    Also one other thing........as far as exhaust exiting before the rear wheels......better check with your state inspection requirements........up here in the Northeast, unless the car came equipped from the factory with them I.E AAR,T/A, you must have full length exhaust on a passenger car......trucks can still have stacks as it exits aft of the cab. Just sayin.........

    We just completed a side exhaust on my 71 Demon. We thought we do something a little different. The picture is not great but you can see that the exit is in front of the rear tire. The underneath picture shows it better. We used 3.5 pipe and the muffler is inside that pipe right in back of the flex piece that lets the motor move.

    If you cancel out the ad on the first picture, you can see the exhaust from the side.

    No, it is just below it. We did have to make an exit for it through the frame connecters though.

    It looks nice and tight against the under body.. I'm running 3" exhaust and my square tips are 10" long so I was planning on having to cut the seem weld to make it hug like urs.
