I have a NB8a and looking to upgrade the full exhaust.

I know this has been covered in various ways before but what is the best way to go:

X Force headers (Around $480)
CES Headers (Around $800)

The rest of the exhaust will be a pretty basic 2 1/4" and the only other mod is a pod style filter.

Would ideally like to hear from somebody that has had or experienced both.

Or the other option is to leave the standard ones in place.

Thanks

got ces here & very happy with them, but given improvement is small & you're not doing the rest of the system, which i did, may be x-force is the wtg. i remember someone commenting on getting a good result with x-force headers:

I had XForce 4;2;1and went to RB 4;1 and lost power.

From our dyno tests on an NB we know headers don't make a big difference (at least not as much as on an NA8)so i would always buy Xforce and save the money.

A good steel cat gave 4 RWKW on Chris h's NB8B so that is a cheaper and better option than headers if you don't want to spend the $$ for headers and cat.but you will need a free flow system to get the best out of either.

wow 4rwkw from a steel cat?? time to install the one i have sitting here...along with the xforce headers

if you're looking for a cat, i'd go for http://www.metalcat.com.au/

not sure how much they cost. group buy?

this is the setup i have on my NA8:
xforce extractors > metalcat > single resonator > generic JDM (jasma approved) muffler

whole system is stainless 2 1/4", and is a bit noisy when fully warmed up. bought the whole kit for cheap expecting minimal gains, but gave an impressive improvement - it has considerably reduced the need to downshift when driving up hills. the car also has a loch stewart mk2 (mania style) cowl intake though.

Id be interested depending on cost.

im interested too for a group buy

Ever thought about the Npower headers? I must say for the price the quality is pretty damn good.

Added a nice tone to the exhaust too.

Unsure of power increase, I changed slot of things around before I have dríven it with the headers.
