noise is largely determined by teh number of resonators you have and what kind of muffler.Quote:

i don't think you will be sacrificing any top end by going down to 2 inch over a 2.25 inch.
but anyway, get what you are comfortable with. no use getting something u dont want cos someone told you so. then later thinking "damn, i should have gone the bigger piping"
if you can afford it, always get a japanese brand name exhaust. the quality is a lot better. CUstom exhaust makers just whack some piping together and weld it.
once again, exhaust tuning is much more important in NA cars than turbo cars, and doing it incorrectly you will lose power.
Vti-R came stock with a 2" exhaust, i only changed extractors,cat and rear muffler becuase those were the most restrictive parts. Out of everything the most restrictive part was the cat
Ummm i read a huge write up on cats... the power difference between a cat and no cat on a 200sx was like .1hp or something. I mean it could be different with NA but how much different.Quote:

the s15 200sx came with a very good cat straight from the factory.Quote:

i would imagine that running no cat would give a more significant power gain as that restriction would be totally removed.
Hey yeah kit sorry mate your right 2" mandrel bent is better than 2 1/4 mandrel, ross said that 2 1/4 mandrel was overkill.
I asked him if i should bother upgrading to 2" mandrel (remember more money in his poket) and he said no. 2 1/4" press bent seems to work better(i say better but i'm sure its exactly the same) since it has the flow but the restriction where its needed.
And yeah the extractors are $550 mandrel bent in polished stainless. From what ross says they're as good as any other bolt on brand... I cant judge but i trust someone whos been working with exhausts for 25 years and learnt everything he knows from someone who was sort after in the aftermarket exhaust industry.
heres the site if your intrested. Let me know if you want his contact.

E.g. the xforce dump pipe is a direct copy of the HKS dump pipe.
they are a good price tho, you should be able to get a bargain.
I dont mind if its a direct copy... so long as its high quality/perfomance. I'm sure if it looks dodge ross would send it back.
The theory behind the design seems to work well. hope it does in practice.
nick whats the name of the exhaust shop your going to?
Morkz,... thakns for the info... hey so if its 2" (and i've been asking around) ppl say thats way enough for a 1.6... so basically if i do muffler/extracters/cat... it'd be good? wouldnt be ne difference if my PIPING was from a cool brand name?
i'm thinking of going Lukey, but i found a mugen muffler going for 250... so might go for that
if you found a genuine twin loop mugen muffler for 250 bounce on it!
but check to see if the condition is OK shake it to see if theres anything loose inside.
I would say get a high flow cat, and cat back piping for now, and then wait around to see if there are any brand name extractors for sale on the second hand market.
its very important to get good extractors.
it all depends on what goals you have for the motor. If you eventually plan to drop in cams and other internal mods dont hesitate to go 2 1/4.
