yo i got a 2005 wrx wagon and i am now ready to put exhaust on? i was wondering if i should get a turbo back if so which ones do you guys suggest or catback with a up and down pipe (Which do you suggest?) can you get more power with a turbo back or is it the same?

 

All a matter of what you want. I wanted a turbo back so I bought an APS 3-inch system and never once have I regreted my decision. There is so many options so figure your goals for your car and research. If you find something you like don't hesitate to post a thread with concerns you might have. Good luck

 

Most will suggest helix if you're no concerned about money. If you want a save a few bucks, the HKS is a great DP for the stock turbo.

As for exhaust, it really depends on what sound you're shooting for.
Try this for some help deciding

 

I bought a turboback just for the fact that I wouldnt have to mismatch parts, but downpipe, catback systems work great too. It really depends on your budget and sound preference. For the most performance, go catless and with full 3 inch piping.

Before doing a turboback/downpipe, I would recomend a catless uppipe and intercooler hoses. Quicker turbo spool, more airflow and the turbo is safe from sucking in chunks of catalytic converter.

 

do they all put out about the same power it is just what i want it to sound like?

 

perrin twin tip

 

You will more than likely get the most power out of a turbo back system. I have the APS twin tip and it looks stock, sounds great, and was easy to install.

 

would a helix up and down pipe go good with the perrin catback?

 

Yes it would.

 

Helix UP/DP+Perrin = LOUD !

 

really would it be real loud or just loud its for my sister so i dont want it to loud? what are other good combinations? or should i just get a turboback

 

Helix up/dp and Borla Hush Catback, not noticeably loud until you get on, but has a real nice rumble to it at low rpms.

 

+1

A very nice set up would be:

stock DP
3rd cat delete pipe
Stromung Dual Tip Cat-back

You will be very happy

If you PM me with your I can send you some photo later tonight.

I'm running a full Perrin Turbo-back now and It's LOUD!

Lowball

 

is helix catback any good and can i see that pic. if i have a cai and a reflash would i have to get it tuned again after i put exhaust on. what is the whp gain with a uppipe and downpipe and catback? what system gets the most helix said 30 whp with all is that good? what would be a good uppipe for a 2005 STI also?

 

The Helix catback is quite popular and it sounds great (a bit loud though). You'll be able to get roughly 25-30whp with a Helix uppipe and full Helix turboback exhaust.

Here's a pic.


Let me know if you have more questions.

Thanks,
