What Best To Use? For Rb26dett

[godzl1975]

hi guys

Am wanting to improve my exhaust flow, have 2530's, any recommendations on using dump pipe, exhaust manifolds for RB26dett? Have a kakimoto front pipe in place already.

Options so far are:

HKS Dump kit (dont know where can get manifolds from)

Tomei Dumps and exhaust manifolds

Nismo Dumps

Power Enterprise Dumps (bit $$$)

Dont want to go for the Ebay options at this stage. thanks any input would be appreciated.

A topic that i have been umming about for some time.

i wouldnt bother with ebay dumps at all. as they are just hks copies? (correct???)

But thinking along the terms of a company who makes things that just do their job, mines would be a nice step. they are very farmilir with 25/30's also. and i would think tomei would be a good go aswell..

What i would like to know is split dump's are they really that good compared to something like mines and tomei's

i was thinking of getting the trust kit. as it includes a larger than what i have now front pipe. and will match up with the rest of the exhaust i also have but looks like a nightmare to fit.

Now getting down to straight up facts..

Tomei outlet is 76.3

Mines which is 70 but appears to have some sorty of small split? or just an odd shape..

Now the trust front/dump

70main 38split 80end

i've also seen versions of the trust with a bit of flex.. which i hope is what trust make as that thing would be the worst to fit without flex involved.

And hks 60.5 and 38

Power enterprise cant find any information about them at all tho

hmmm there all good products dude i guess its upto you and what you can get cheap.

Also look into your cast manifolds. and having the extrude honed. As you will find that alot of aftermarket stainless ones are prone to cracking.

thanks guys have decided to go for the Tomei items....the exhaust manifolds and dumps. have thought of doing that the extruded n honed option...but for not much more can go for the tomei ones...with the cracking ...read a thread by SK and how not many people take into consideration of exhaust supports so will look into that placing more supports if possible and not get a crack in the manifold. hopefully will get order in as soon as i do my tax return

id personal put in the extra cash and get the trust ones.

those are split for a nice length and will help greatly over just a single open pipe.

yeh but dont want to really go that option as i have a kakimoto front pipe installed already.

r31nismoid knows the deal on 26 dumps but i believe the trust ones are the best bang per $

I'll be running the Tomei manifolds with Trust dumps/fronts. They have flex pipe.

The Tomei manifolds are investment cast, not drawn... and very damn nicely made.
