What is regarded as the best exhaust at the moment? I am looking for...

* Something made out of titanium (to save weight)

* Something that is legal (or close to it :P )

* Something that will not harm -- or hopefully -- will improve response.

Also, has anyone tried one of the Apexi hi-flow 3" cats?

meggala, good to hear you got such good results from the turbo and glad the thread was of help. Pretty responsive little package you have there - I wonder what the advocates of never using bush bearing turbos would say to your results?

two people that just dont get it then.... your gunna kill your cars...

so it would follow that my car shouldnt be running.

where do you get your info from? heresay, or actual experience? I can understand concern for someone who may damage their car, but dude, give it a rest - your not their mother.

I had no probs at all running on base map in summer. when it made it to the dyno it was rich everywhere.

but anyway, thats a bit off subject

You mean the Apexi N1? What about the Ti HKS's?

Has anyone actual done a comparison of the various titanium exhausts lately?

Edit: I should have added, it has to be turbo-back for R32 GT-R

I have never taken my car down the 1/4, when I drive hard, I like it to last a bit longer than a few seconds. It is a daily driver. Not huge on cruises, prefer to go for drives with smaller groups. Cruises tend to attract too much attention and end up stuck behind guys who may not be too interested in a spirited drive.

BTW DJ, are you going to answer my questions?

LW - That's the exect same exhaust I have - It seems to go well.

330 rwkw @21 PSI - HKS 3040 - similar setup to steve. Boost starts at 3000 RPM and I have it all at 4100 RPM.

Can I ask where you got it and how much you payed? (PM me if you don't want to post)

Cheers,

LW,

Did you follow the links I posted back here, about the HKS Ti Drag system ?

It works a treat, but it's different from the other HKS Ti systems, many of them only have a Ti ail pipe.

Yup, was rather impressive. Just trying to way it up against other titanium systems.
