[Supras] losing performance

[Rockey Fox]

Dan, thanks for the feedback on the pipe itself, I was thinking of getting one myself and probably will now.

I have the speed-source lower IC pipe installed on my car.  It's
 low-cost, and is at least a 
hardpipe and gets rid of the stupid elbow.

My thinking is this:  Most of the restriction to FLOW in the IC system
 is the IC itself, and 
it's flow that we're interested in.  Most of the problem with 2" piping
 is the number of 
bends and twists in the stock system anyway.  The Speedsource pipe only
 has 2 bends in it, 
and it's not a very sharp bend at that.  As such, I think that it's
 perfactly suitable for 
making some decent power.  Certainly it can be improved, but I think
 that it's well worth the 
money, and I'm not planning on replacing it until after the rest of the
 intake is all done.  
Even then, there are (to me) many things of much higher priority than
 that pipe.  As a 
replacement for stock, it's definitely better.

I'd prefer this over a 2.5" IC pipe that's made from bends and put
 together with silicone 
couplers.  The transitions at the silicone will produce turbulence and
 drag in the pipe, 
which the one-piece 2" pipe won't have.
