well spoken. turbobacks are your best bet- and pretty much your only guarantee that the exaaust flow will be consistent from turbo all the way through the back.

when you go "piece by piece" some catbacks are tapered slightly. i haven't seen any real negative numbers in reagrds to this- but still i'd recommend a full turboback regardless. i have a PDE/Tanabe CB combo- should saved up for a rsr tbe or some other jdm tbe.

gdogg, I just picked up my 05 Sti about 5 months ago and I am about to pick up the same set up as you......but you sound like ur not too satisfied with it.....

I just ordered the Ultra Medalion and will be getting a PDE catless downpipe soon.

Bump for the Turboxs RFL. Installed mine today, even tho it was a pain in the butt, it was worth it.
