Im considering purchasing a craford plenum V5 and set of headers...should i just get the craford headers or is there another brand that would perform better with the plenum such as stillen?? any input would be appreciated

Talk to Doug at Crawford. Hell set you straight. =)

Nope - Crawford is the best header. Don't forget the hi-flow cats.

yeah...i would think that that is a good idea...im going to wait until the APC one comes out...looks a lot nicer...heard some horror stories about the crawford anyhow....

the major question is with all the mods im doing to the air flow in this car (p/c, ztube, plenum, y-pipe, and possibly headers), does it pay to get a better exhaust? Am i going to see significant gains if I replace the exhaust after all that other work has been done? I like the stock (z-tube) sound...kinda throaty...i dont want to sound like a rice/fart can..hehe...i like the ALMOST, but not quite v-8 sound it has right now...how many horsepower you think i can expect to see with the addition of the exhaust after all those other mods? i would expect if it is a significantly restrictive exhaust, then i should be seeing atLEAST 10-15hp cause i will be freeing up that last bit of the pathway, so all the other mods will be working at their peak...

i guess that leads to the question of can i have too much flow? i know the engine needs a certain amount of backpressure, i dont want to approach that 'diminishing returns' curve, so to speak

It ain't just a Nissan!

 

May I ask what horror stories you have heard about the Crawford plenum? I have had two (a V2 and a V5). I changed for cosmetic reasons only. I have had no lissues, nor have I read about anyone else having any issues with the Crawforrd. IMO, it's the best bang for the buck out there. A truly great product, developed by guys who really care.
