    Our proto system below is sold, but putting some feelers out to see if there’s any other interest(?). Would be available in brushed (shown), polished or black coated. Dyno numbers below. Yes, I’m aware of my competition with these, but you can see the results of those in a short amount of time via the bottom pic below.

    @GTM® These are by far the best sounding pipes you've done so far.

    Those do sound Awesome - but Im happy with the ones you made me !
    Since they do away with the o2 sensors = the need for the Tune ?

    I like my V7 III megs the best personally... but these do sound good.
    Pretty much. Amazes me of how many people buy them ($$$$), and how many we've replaced in the shop.
    That is correct.

    Looks absolutely wicked Todd, I'd be interested if I hadn't already purchased some super short Stingers.

    Related question, are those replacement machined flanges for the headers as well? The only ones in the store are for Big Block motors AFAIK. If so, I may be interested in a set (not right now but it would be a welcome upgrade down the line when I have some pennies).

    Thanks, dyno chart posted above now as well. they're decent performers once fuel corrected.
    The flanges are not able to be removed on the stock system, nor my system, as they are installed prior to production/welding. They come with every full system I sell. ;)

    Those dyno results tho... Makes me want to put mine on one!

    Makes sense about the flanges, was already looking at some replacement headers anyway :) (wayyyyy down the line, being a recent university grad, loans tend to take the most of my spare cash.... saving up for an SAS kit and a few other bits and bobs from you either way!)

    Keep killing it Todd, hopefully I can throw another order in soon!

    Are these significantly louder than the v7 III GP or Stinger megs? How about relative to the Stubby Mufflers?
