I Have an 06 wrx TR, just installed stage 1 cali maps a month ago (runs great). NOw, im thinking of stepping up to stage 2 (i want more power). which downpipe do you guys suggest me getting (i like to avoid boost spike, boost creep as much as possible). pls help.

im thinking of getting:

invidia catted downpipe or Helix w/high flow cat

Wat do you think of these too? did anybody had experience on these? how are they? thanks yall

 

I have the Helix w/highflow on my STi & I like it alot. The quality looks very good (good welds, plating etc). It fit perfect, no leaks.

 

cool thanks, any noise? did your ur exhuast sound more exgressive (as in good sound) or the same?
i might just get that. thats the bellmounth right?

 

I purchased the TurboXS stealthback for my '06TR, and LOVE it. Looks stock when I use the factory axleback and just a slight increase in sound, but on the track days I put on my MoZart exhaust and it flat out screams. The TXS DP is 4" at the bell mouth and slowly tapers to 3" at the axleback portion. It is also a very solid piece.

 

I have the newer invidia dp to a tanabe ultra medallion exhaust system. I had them weld a straight adapter from the exhaust to the down pipe to get rid of the bottle neck. Love it. Sounds great, fit great (welded adapter because of want not need). Not really a fan of the tilted exhaust, but it gives you one less bend i reckon.
