What is your 06-07 WRX Stage 2 Setup?
Right now, I think I have most of the Stage 1 mods done to my 07 WRX:
1. K&N panel filter
2. Intake silencer delete
3. Perrin lightened crank pulley
4. Cobb AP Stage 1 flash
This coming spring or summer, I hope to make the jump to Stage 2. I already have the Cobb AP, so I think EM is basically set. After doing a little research on turboback exhausts (reading about the different designs and watching the video clips on YouTube), I liked the Turbo XS RFL-Ti turboback system the best. One of my concerns is that the Turbo XS downpipe is catless and I read that the 2.5L engine in the 06-07 WRX needs a catted downpipe to help prevent boost spiking. If I get the high flow cat in the pipe immediately after the downpipe, will that solve the boost spiking issue along with a Cobb Stage 2 map or should I get a completely different downpipe with a cat already built in to it? Also, it was hard to tell from the videos because it sounded different on every car, but is the Turbo XS turboback exhaust one of the loudest on the market (I don't want to piss off the neighbors too much)? I'm not completely sold on Turbo XS yet, but if I go this route, I think I'll need to buy:
1. Turbo XS 4" bellmouth downpipe
2. Turbo XS 3" cat pipe with high flow cat
3. Turbo XS 3" midpipe
4. Turbo XS 3" Ti tip
5. a turbo heat shield (Cobb, Cusco, or SPT - I haven't decided which one yet)
Am I missing anything?
Is anybody else running this same (or a similar) setup on their 06-07 WRX?
If not, what Stage 2 setup does everybody else have on their 06-07 WRX?
Thanks for any info!
