Would this exhaust pipe flow enough for my setup?

    yeah.. that's kinda what I figured you'd be up against here.

    The mufflers would have to be moved way up front(not even doable if you want an crossover/x-pipe in there).. and slanted outwards at the rear to start the transition towards the sides without having so much radius to get there.

    And then there's the plane that the muffler/pipe is on is almost dead middle to the center of your connectors/exit pipe centerline. Whick brings me back to the dip and upwards angle to get the exit where it needs to be for clearance and looks. Also very tough to do that with oval pipes.

    The only reasons that I know all this is that I've literally laid under my car with measuring tape for almost hours on end to get a feel for what's possible on these short wheelbases. I will likely be notching my rear frame to create the clearance I need to get what you're after here. I may even go so far as to cut exit holes in the front section of the rear wheel wells to come out nice and tidy. Lot's of work though.

    If you really have to have the side exit...AND you want to get creative...Cut a hole through the frame rail (Then box it to keep rigidity)...Cut a hole through the rocker panel where you want the exit to be.(Box it to keep the rigidity) You can now run your pipes through the holes and side exit them...AND you have just avoided half the pitfalls you are faceing, includeing the whole ground clearance issue.But it will take some careful thought, fabrication skills to pull off...Its' the only real way I can see you getting your side exit and keeping the cal tracs/ SFC's Good luck man!!!

    Funny that you guys both posted the same suggestion within a minute of each other.

    I am not that good with my fab skills, so I am destined to live with dump-at-axle exhaust...:(

    The clearance, or lack of it so close to the back tires is really only a concern if you have lots of speed bumps where you drive it. Otherwise it's no big deal.

    the one thing with with oval exhaust is that it doesnt promote swirl. their is some talk about that factor making it even less efficient than just the reduced area.
    but i believe that nascar uses oval exhaust and if it works for them their has to be something to it.

    I think there's more to it than just clearance issues. IMHO, if you drop the exit pipe that low to get underneath the connectors.. won't it just be hanging out in limbo below the rocker? I see plenty do it.. and it' looks less then tidy and planned for aesthetic's when you stand back.

    and the nascar guys only use it for clearance purposes and have to add tune for it. Any tumble or swirl only robs energy from the flow column(although there are some tests that show improved scavanging from it in exhausts.. like flushing a toilet). About the only place it's sometimes worth it in an engine is to aid in fuel breakup and burn characteristics in intakes and heads/cylinders. Many of the big names would rather "pour" in the correct mixture.. than "tumble or spin" it. OEM's mainly do it for emmisions.

    I LOVED my sidepipes! They were one size too short, but looked good, sounded GREAT, and everyone loved to see them on a period-correct car!

    They were impossible with long-tube headers, so I had to get rid of them.

    Maybe it is time for shorties and another set of sidepipes??? :huh:

    I had side pipes on my Falcon with long tube headers. Only reason I got rid of them were because I got tired of getting a new tattoo every time getting out of the car.

    I was 200 there, got to 210, now down to 180. Was 175 but Thanksgiving and Christmas were difficult times to keep it off.

    The angle of the tip exposed to the airstream has a lot to do with scavenging too. Has anyone noticed the newer diesel's exhaust tips ? They're built with a venturi in the pipe now to aid in scavenging
