which up pipe and downpie should I buy? Invidia, Helix or APS? Which one will give me the better perfomance? Also do they make an aps turbo exhust thats 3 inch but has a bigger muffler on it? I want one that looks like the 3 1/2 inch aps muffler but i don't want the 3 1/2 inch turbo back ( to much air flow for a wagon)? I am driving an 05 wrx wagon, the plan is to buy a turbo back then get it flashed and tuned, then get the up pipe and retune it. Please help?
Also is helix any good? I ve heard good and bad things about it but what scared me the most is a friend had a helix turbo back and up pipe, after a week he broke it. Any way any suggestions on the topic will help, if you are running something else and just love it let me know I am up for suggestions. Thanks.

 

helix.. and im wonderin how the heck your friend broke an exhaust???

 

Helix

Wait for the Helix Titanium catback coming out in a month

 

thanks for the suggestions. Is the helix loud? I want the car to sound mean like the sti with exhuast. I was thinking about getting a different catback like the apexi n1 or gt spec. Also where can i see pictures of the new helix? Also do they have thier own web site yet?

 

If you want loud and mean just spring for the 3 1/2 inch APS even though you said you didn't want it. All of the exhaust you have mentioned are awesome. I have the APS 3 inch and love it. See if you can find any post that have sound clips of them all.

 

3 1/2 is just to big though. It will cause to many back pressure problems and I will lose low end torque (which I can't have, I love the low end power). Any other suggestions like maybe a different catback?

 

its a turbocharged car, while the 3.5 might be overkill(meaning you may never reach a hp level that needs the 3.5 inch) it will not have anyless torque because of piping size. You want to spool the turbo as fast as possible and getting the air out of the turbo can lead to faster spool up and faster spool is what makes torque.
