Default Could this be my power answer...

I'm pretty sure I found the answer to my N/A RS power concerns... My mods include Cobb Intake, Fidanza Lightweight flyweel, Nology spark wires, and ProECM chip. My car has always seemed sluggish for an RS with those mods, especially in the high revs. I'm pretty sure I found the answer though... I have what I believe is the stock exhaust from a Legacy L 2.2 on my car. The piping is either 1 3/4" or 1 7/8", but either way it isn't very large... and smaller than stock RS piping I belive. Anyone else think this might be the missing link to finding that little extra kick I've been missing?

Also, can anyone lay out some symptoms of a plugged catalytic converter for me? I think I might actually have one of those also...

Thanks,
Scott

if you got the moola... might wanna check out these headers + hi-flo cat.

soopa shexy.

As for the exhaust... yah.. just find a 2.25" midpipe and some free-flowing can and you'll be straight. Remember, all these breathing mods compound on each other. My car's pretty fun with almost all ur mods. Just replace the ProECM chip with Cams.

running that stuff on a stock exhaust?

try upgrading just the cat back.

IIRC stock pipe size is 1 7/8ths

on a n/a scooby you shouldnt go any larger than 2.25

Nope, an exhaust even from the headerback isn't going to make a huge difference, maybe 10-15HP. But combine the exhaust with cams, and I think it will make a good difference. How much did the lw flywheel help out? I'm putting a Exedy Clutch and 13lb flywheel on my car this Sat, and I'm having some street cams installed the week after to satisfy me until I can save a ton of $$$ for my turbo project. Also, get some lw pulleys, they make a fairly noticeable difference. And going to 2.5" isn't a bad idea if you have a fairly modded N/A car..

Stock exhaust piping is 1-7/8, so no worries about a Legacy exhaust on your car (Legacy is a bit longer, besides).

Plugged cat? Why would you think that? You'd have a CE light, most probably.

How many RSs have you driven? What were their mods, compared to yours, to make you think you're not getting "full" power?

I know the answer to your problem. Get rid of the Nology spark wires.
