Letz talk exhaust !!!!!!!
i afew weeks ago a certian memeber put his nur specs up for show and it got me think i am going to be jz swapping it soon its time to put up or shut up.
i have been searching high and ow for a nice system to support my t61 all i have seen are hks systems . i've looked on supraforums and from what there saying the ebay ti is really good but what is ur opnion guys NO MAGNAFLOWS no a fan of them so far i picked the
HKS universal Ti
blitz nur (if i can find 1)
carbon TI
or just open DP

4" dp/mp to dual 3" double offset straight through Vibrant Performance mufflers; numbers are in my sig.
WG piping blended back into 4" DP:
4" Y pipe to dual 3" pipes hung on OEM hangers:

I couldn't be happier with the exhaust. It's actually very quiet yet performs very well. Plus, dual 3" exhausts are larger than a single 4" pipe. Consequently, the piping just gets bigger as the exhaust flows out the back.
FWIW, opening the exhaust was the single biggest improvement in performance especially when I installed the T74. The motor gained almost 4 psi of base boost pressure when on the wastegate spring, and it made nearly 150 more hp from it's original custom exhaust because the turbo spooled 5 psi more at high boost (was 28 psi; now 33 psi). Basically, a restrictive exhaust will keep a turbo boost-limited because there is no pressure differential across the hot side of the turbo.
I will never again underestimate the need to get exhaust gases efficiently past the turbine. ;-)
