MAte, if you got a choice go the split dump pipe. There will be less back pressure due to turbulence.

I got a 3" straight. A few people have done back to back performance and noticed some improvement.

i'm tossing up between ditching my front/dump pipe and going the split.. just don't know if the gain is worth the money.

I guess it depends on your level of mods as well.

pav,

spoken to lotsa ppl on this issue, unless your shooting for more than 250rwkw, its ok to run either pipe. You will only see a real noticeable difference at high hp.

so as on that note, why screw around with a great exhaust set up that nissan give you, dont worry bout the split dump, just get a 3" straight pipe put it. under 250rwkw the increase is the same.

cheers

When I was shopping/asking around for a dump pipe, I heard literally EVERY single theory about split Vs. all-in-1 dumps, and this wasn't just from 1 or 2 dudes, we're talking 10+ professional opinions, nearly ALL different ! !

It pretty much came down to these 2 theories:

Pro-Split: The nice smooth run of pipe out of the exducer flows better, and helps spool-up, because the gas's inertia isn't upset by the turbulence You get with the wastegate in the same pipe.

Anti-split: The gas coming out of the exducer is rotating and as turbulent as it's possible to be, it can't get any MORE turbulent, so as long as the pipe diameter is there, and there's no big blockages, it's all gunna flow as long as the backpressure is kept low. The gas has done all the hard work, now it just needs low backpressure & a place to go !

Make up your own mind, I got My X-Force 3" (non-split) dump for $150 in mild steel, not bad eh?
