MY NEW LONG TUBES
#51
MBWorld Fanatic!
The question may become (at least, in my non-exhaust-engineer's mind) "in this application, are fatter tubes better, or equal-length runners better" - from the pics, this setup looks to be as compact as possible, with little wasted-space; perhaps unequal is the only way to fit pipes this big? If you could (hypothetically) fit 1.5" pipes equal length, or 1.875" pipes unequal, which approach would net the better performance returns?
Agree w/ others; the dyno results will be interesting to see.

Equal length primaries are not better than unequal length until after 700hp (even then it's an "maybe") with regard to a V8. More important than equal length is primiary diameter. I'd like to know what the dia is of the other LTs on the market, because I doubt they're 1 7/8"--likely 1 3/4".
As for the collector "neckdown" that's something you see with ALL high velocity merge collectors (again it's all about the collectors, that's where the power is made). It's not as large of a neckdown in person as the pics make it out to be.

After listening to all of the BS hot air from Andy and later testimonies from Jackpro can't say I would trust a thing from you guys!
