The best setup for RWHP is:
TPIS -> Dr Gas X pipe -> Stock H pipe
I do not have the stock H pipe as someone installed a X pipe homemade in its place. I have fabed up some pipes temp but not what I want. Maybe I should just have some 3" custom exhaust made and dump the Corsa.
call west coast corvettes.
they had an overstock of the RT system for the TPIS lt's. clearance prices were half of the direct price.
i've sent 3 others thier direction, all purchased for just under 450.
ask for brian or paul (cant remember the contact name).
good luck.
btw: the rt system slipped in and bolted right up...took me 45min to install with jacking up the ride in my garage..just fyi..

with Phil. This set-up actually made more hp/tq(+4) than the LG off-road exhaust I'm using now. The only other difference was the Z06 catback then vs Stingers currently. At least it sounds better now. Maybe a re-tune will find the lost power.
