Dont assume just because your going long tube you will see more gains.
there are dynos where there were very minimal gains on long tube headers

Regardless I ended up purchasing isr long tubes instead. The ISR shorty's weren't in stock for another 4 weeks, and I can assume ill get more gains going to the long tube route especially, since Im doing 3in intakes and and upper/lower ported plenum/ intake manifolds.
