long tubes give you more of a down low grunt, and shorties are up high.
the x/h pipe is very debate which is better, IMO if you want a raspy sound and more top end go with the X pipe, and the H pipe will give you more of a mid range power with a more muscley sound.
they react to pullies like fat chicks do to salad something bad is going to happen.

i have a few questions
long vs shortie headers? why are longs better?
X vs H pipe. Is x any better over h?
how well do the machs react to pullies?
Technically an X pipe will yield more power because it flows better. Scavenging effect?
The difference will be minimal in power gains though. Maybe 2-3rwhp difference between the two. Pick the one that will give you the sound that you are looking for.
I have heard bad things about pullies on Machs. From what I have heard, the cause the oil pump shaft to break and that leads to nonfunctional engines.
Nice mod on the Pro Charger but you left out Cobra Throttle Body and inlet. Hugh difference over the stock. Stock produced 1089 cfm and the Cobra Throttle Body isfull 1700 cfm. You will gain another 24 HP and 18 lb/tq just from the throttle body and inlet. It will set you back $600 but it's worth every pennie.

Their are a difference between X-pipe and H-pipe by brand. BBK make's H-pipe and they suck. SLP and Bassani make's the best X-pipe.
Long tube headers are better because they are equal length by design. If you have a pair of equal length shorty headers they are equal to the long tube.

Turn around for intakes is ~10 days, for head work ~3 weeks.

I'm very interested in the gains for each. On M1R, I saw ported non-runner intakes show gains of 10rwhp on a near stock vehicle, but wondered about theshort-runner gains. Also, anyidea whatP&P heads would give for gains? I knowon2V's and 3V's P&P head gains are in the departmentof 30-35rwhp on near stock vehicles. Both would definitly seem worth the gain if one could installthe parts themselves, but I still wonder the gains/gain ranges of the 2 parts that I don't know.
oc192, $600 for a throttle body and inlet with 24hp/18torque gains! Nice, what other mods were on the car at the time of the dyno, gains from the inlet and throttle body? Is this a part you can just buy from anywhere or need to find used in a f/s section or junkyard?

Sorry for the slow response. For the 2V and 3V motors the PI Stange I II and III are making serious power. But you have to do the complete package. Patriot Performance are making the best heads for 2V. If you go with their complete package you see and feel the difference. Unfortunately; you are limited how far you can on hp because of your botton end. Please check what are the limits how much power you can make on your motor.
