Default Exhaust Setup

I might be selling my WRX and getting an 05 RS soon. I was looking up info on exhaust info for the RS and I found some real good information here. I was thinking of going with

Borla UEL Headers
Stromung Catback

With this set up would I need any other piping or is just the headers and catback ok ? Also is it nessacary for a tune after these mods ?

Should be everything, if you're planning on using the stock cat section.

Good luck finding someone who'll be bothered to tune a NA car. The ECU can handle bolt-ons easily enough, though, so it shouldn't be a problem.

borla + stromung is a mean combination.

get the borla replicas off ebay and not the real ones. they don't crack and sound the same, if not better. plus they're cheaper.

stromung is epensive, but sooooo nice.

Def UEL header setup, maybe HFC is you like, and stromung catback.

I have a stromung single tip XA catback on my 07 (remember I have EL stock headers) and it still sounds awesome, deep and throaty but no burble/boxer rumble. To be remedied in 08 with UEL's an HFC setup.

The stromung is kinda pricey but one of the best exhausts for our NA cars.

Firstly, the 05+ RS/2.5i's are all tuneable with free opensource software and a laptop. You will need a tactrix cable to plug into the ECU. (~$65+) So you can tune it yourself in addition to logging, pulling codes, etc. RomRadier is the best software to use for this.

A tune isnt "necessary", i mean the car will work and drive just fine. it may be hard to feel any difference in performance without a tune. With a tune you will get much more out of the car, not only from the headers but from the ECU's conservative CL/OL delay and rediculous rich OL fueling being changed. I dont know how much timing you can throw at it with 87 oct. the Stock ECU maps and stock engine combination are already pulling timing on all the 05+ RS/2.5i i have seen. The borlas would probably allow you to use the rest of the advance already in the stock timing advance tables and maybe a bit more. Williaty would be able to give specifics since he had that combination recently. Im just guestimating. If power is what you are after then EL headers are the way to go. with a tune, EL's will allow a significant amount of timing advance to be applied compared to the Borlas (UEL headers). A high flow cat/catless would be another way to get more power.

Also, welcome to the N/A world. You will probably be dissapointed.

well reason being that my car isnt running very well needs some work and $ that i don have to put in. Insurance cost is insane (stupid NJ) as well. Im 18 yrs old I really dont need the headache of a un reliable car and a car that I can barly afford. Most likley I will keep the RS for a yr or 2 and try to save up for an STi.

Yep.

I wasn't saying 05's were unable to be tuned, I was saying its not like WRX or STI's ... most shops wont touch 'em, either claiming waste of their time or not big enough gains for the money.

Perhaps the shops up here just suck, though. I should hurry up and buy a laptop, cable, and books.
