WRX Performance Exhaust
In Subaru performance magazine they only claim a 3 peak hp gain with the SPT cat back @ 70 mph. I think the Blitz Nur spec claims around 15 hp. Like Choku Dori said, Its really loud but if you put the silencer in it isnt bad at all. Im sure the silencer will make you loose some hp though.

I'm not too sure about that. As far as sources tell, you really make no performance gains from removing it.
Are you talking about the silencer that is inserted in the tip of the Blitz Nur Spec or the factory reasonator?

I was kind of thinking that also but I thought it might loose some power at the top end.

hey! nothing wrong with a Dodge 600 Turbo with an SSQV 
seriously, there really IS no whoosh with the intake elbow delete. I mean...if you listen REALLY REALLY hard, and its quiet all around, YOU might be able to hear it in 2nd or 3rd gear before the road noise overwhelms it at higher speed....but its not loud enough for anyone to notice. I think it was a waste-of-time mod. However, I'm currently trying to fabricate a water resevoir that will fit into the empty fender space for an intercooler sprayer. I figure I could get about a 2 gallon tank in there if I can figure out how to shape it right, secure it properly, and locate a fill and drain pipe into the motor compartment.

Oh, and when I tried it, I took the whole thing out, not just the elbow. That's probably why the whoosh was so loud.
