Hipex 2146 Terra .21 Off Road Tuned Pipe Set w/L44X Off Road Manifold
good pipe, but more leans towards a buggy pipe than a truggy pipe so one might be more aware.
just in case if One was looking for a pipe for a truggy, for truggy a 2090 or similar "Pipes" of same design be better!!
or the FlashPoint 2146 (same as the O.S. 2090 in its primary design function)
so for buggy, a good 5 star rate, but truggy can be good! but under more specific conditions where some may or may not notice? the effects as a example.
as for another point, longer manifold more bottom end for a "Given type of Pipe"
but even then a longer Manifold wont always be the same Bottom end one would be looking for for a "Given Pipe" etc.
so a Midrange pipe may not yield same Bottom end desired as a Pipe made for Bottom end w/long Manifold for a truck etc.
it is easier to "Tune Down To" then to Tune up from.
not like the "Holy Grail of Pipes" the Nova 9901 which worked great in both truck and Buggy!(no longer made!)
which was best, Short Manifold and 9901 buggy! long manifold and 9901 pipe Truggy! and was stump puller.
but tried on several O.S. and SH and STS motors including a few NOVA P5's !! and worked great! in Buggies!!
truggy as well but under more "Specific Conditions" shorter flatter type tracks with lower flowing jumps with no jumps right out of a Corner etc, and worked "Ok'ish? truggy on some "California Big air" tracks but you "Really" had to set up your Lines to make them, and still? was a little harder? so this is more a buggy bottom end pipe :)
