what would you guys recommend, the turbo xs 4 inch downpipe, or the invidia downpipe? for an 06 wrx. thanks, i just really cant make up my mind and i'm about to make the purchase. I'm looking for the most performance and best sound.

 

There shouldnt be a huge difference in sound. Interesting part about the invidia is I believe it has the divorced wastegate tube. I saw a test in a magazine that showed it had the best HP gains, but also the largets increase in manifld pressure, although it was still under a 1psi increase. They did not however test the XS.

 

I would personally run the Invidia over the TurboXS piece as it seems to fit well with all catbacks and has proven itself to work well on the dyno. Another downpipe to concider would be the Titek which has excellent fitment and value for money.
