Hi all,

Just wondering whether anyone has done a before and after comparison when they installed aftermarket dump pipes on there GTR?

My tubs are coming off (blown) so labour is minimal, and the cost of dumps will probably be around $800.

Is this money well spent or money wasted? I intend to intall N1 turbos and power levels will be under say 280rwkw after mods are complete.

Thanks for your opinions.

Lawrence

Hi Lawrence.

Try doing a search, this question was asked some time ago and it resulted in a longish thread, there are also related threads including one that has an article by a Garrett angineer on design. Unfortunately no evidence of anyone having done comparative dyno testing, some suggest that there is little if any gain to be had. I'd say if you are doing the turbos anyway go for it. CES in Queensland make nice stuff and can give you a dyno figure for improvement using their pipes but they haven't compared their stuff to anything else.

      R34 GTT idle problem

      By silviaz · Posted

      Is the 650rpm idle on the rb25det neo for stock cars only? I've never had my car before and after tuning it to idle at 650rpm when cold. Always idle's cold around 1100rpm, and then drops to about 900-950rpm. I've heard the r33 gtst's idle there.

      By Sleepergm · Posted

      Hi all, I’m currently running a str pipe hi low hks exhaust and downpipe. Was wondering if I change out muffler to a titanium one will it change the sound of the exhaust? Plus I have always liked the look of the titanium pipes … anyone have recommendations to one?    side note already have titanium intake pipes.

      Ha ha, all good! I've almost caved in and realised I'm buying one.  I know myself well enough by now that I will start chasing ADHD butterflies half way through building it and not finish it so I'm better off spending the extra money buying one instead of making one just so I can get into straight away.  I would very much enjoy making one as fabrication is probably a strength and definitely a passion but I don't want that to be at the detriment to the car I'm ultimately building it for! There's some pretty good ones around for ~$1100 at the moment so I think I'll just go that way.  At the end I sell it or as mentioned, get another project to make further use of it! Thanks gents.
