I've been surfing this site for a while, trying to get an idea for what kind of DP + Catback will give me the best performance while still sounding like the stock exhaust. I'm not looking for noise, but definitely looking for some additional torque on my 05 STi. I'd appreciate everybody's opinions.

Thanks.

 

Cobb is a good choice for what you are looking for.

 

x2, a little more expensive but worth it.

If $ is an issue, go with a GReddy EVO2 catback and catted DP

 

Is there a Borla Hush that fits the 05 STi? And how's the Hush's reputation among you people?

 

I just got HKS HI-POWER exhaust and their downpipe yesterday and im gettin it installed tomorrow. I was in the same boat as you were but i went with this. I was leaing torwards the Greddy and dp but went with this. Good looks, good quality, good price. Ill let you know how loud it is and how it runs

 

try PM'ing WRXed he has the borla hush double tip w/pde dp. on a 05 STi.

Funny, you asked for a TBE and no one has actually mentioned one yet...

Catback + downpipe is NOT a TBE; that leaves the stock midpipe and cat.

If you want a quiet TBE, there is a Borla TBE (which is tough to find) or the APS turboback, which is extremely quiet and stock-looking when bought in the 3" dual-tip configuration. If you want quiet, I suggest that you add a high-flow cat to the exhaust, which greatly quiets the sound.

 

Actually that is incorrect. I have the Invidia dowpipe that connects directly to the Greddy EVO 2 catback. So it is infact a true TBE. The stock midpipe and cat are replaced by the combination of the downpipe and catback.

 

+1, this is true in most cases...unless you get a shorty downpipe that only replaces one cat, but no one mentioned one of those.

 

+1 Yup, im running a Helix DP with an HKS TI Carbon CBE and it has no mid pipe. 90% of DP+CBE will make it a TBE. Some companies just offer a complete package for quality and performance.

 

How loud is that setup? I have the hks hi-power and was contemplating whether or not to get a catless downpipe. I'm worried about droning on the freeway b/c I commute every day.

 

Thanks gdogg, PM'ing WRXed right now..

 

Yeah man, let me know! I'm not interested in scaring the birds out of the trees as I drive by, not to mention needing to turn up my stereo, attracting cops etc. I just want a free-flowing exhaust w/o the noise!
