Afterburner on a 2007 2.5 STI Hawkeye
 

Advice please fellow lovers of the burble!!!:notworthy I am about to pick up a 2007 hawkeye STI and i really want to put a nice loud back box that will emphasize the burble. I don't want to re-mortgage the house and I have heard the Afterburner vortex by H&S is pretty good any thoughts lads and ladies??:brickwall

well i had the after burner r.3" version catback,and as it wasnt loud enough ive now got blitz nur spec.,the blitz is deeper and a fair bit louder, i would say.only had the vortex for 4 weeks

I much prefer the Afterburner over Blitz, I had a Blitz Nur Spec on my 2005 WRX before Afterburner, when I changed I was amazed at how much more responsive it felt and how much better it sounded.

Afterburner for me everytime, best affordable system about IMO.

Some of MY07 RB320's have gone for, HKS Supergragger, Blitz Nur-Spec R & Nur-Spec s, with very good burble results.
I also believe that retaining the Prodrive backbox with a de-resonated centre sectione gives a fair bit of burble back!

It might be different on the new age cars but i had my classic fully decatted with a prodrive backbox and it sounded no louder than my honda civic work car. my mate who has a nur spec r on his P1 said my car did not sound like a subaru.Then i fitted an afterburner vortex,what an improvement - not just talking about the noise the improvement at 5000 rpm was totally astonishing car would pull cleanly to the red line,than when the prodrive system was on. i love mine to bits ,but if i were to change would go for the blitz,but for the dosh dont think youll beat the vortex. It is also the most powerfull system made by haywood & scott.

Thanks guy's. your opinion is much apprciated.
