How do i make my car sound more aggressive? (MY08 Lib GT STi

Hey gents,
Looking at making my car (MY08 Lib GT STi) sound more aggressive.

What would be the steps involved in this, upgrade the Air intake?

[senator]

High flow Panel filter like a HKS Hybrid and removing the resonator will provide more airflow, which results in being able to hear the turbo spooling and bov going off.

A full tbe will really give you the aggressive sound your after, I have got a 3" phat dump, 3" customer centre pipe and phat quads, not only did I get a sweet rumble but I also gained extra throttle response..... And the ability to set off a few car alarms in underground car parks.

btw post up an intro and let us know about your car and what plans you have.

Intro well lets see...

I brought my Silver Subaru Liberty GT spec B STi- manual on the weekend (Sat), in VIC. I caught a flight up to Melbourne Friday night and drove back to Wollongong Saturday. The car is in great shape; having only 8,800Km went I got it (it now however has 10,300Km). Mags are Silver with Black Brumbo brakes.

In the short term
1. looking at getting a better sound out of the quad tail pipes (I do like them!) something along the lines of "what the *uck was that" when I drive pass aggressively...

2. adding in an I Pod aux in the arm rest just under the 12 V output.

3. Tinting all the car windows 35% (currently the driver and passenger is 10% but the back is 35%, not sure why???)- Not sure if I want mirror finish or just darkest possible tint (your thoughts??)


Then a while down the track (when I pay the bloody thing off!),
4. looking at changing the colour of the brakes to stand out more (any ideas???)

5. A re-tune after that

6. maybe changing the front spoiler (you know that plastic STi that bottoms out on driveways!) to a more aggressive one...


So yea that’s my thoughts 4 days in of having my MY08 Lib GT STi

Here's what I did to MY07 version of the tuned by sti...now more like tuned by Dave and Allstar Garage. Mine sounds supper agressive now.

Summary of mods and tuning results to date as follows:

Stock power run with panel filter only gets 190 HP & 320 Nm and first tune nets 206 HP & 355 Nm


Panel Filter, AVO TMIC and Dump Pipe w/ stock catback and sti quads plus re-tune gets 218 HP and 414 Nm


Panel Filter, AVO TMIC, TBE w/ Hitech Quads and re-tune gets 241 HP & 428 Nm


Cost to achieve this to date:
Dump Pipe $800
Centre Pipe $400
Hitech Quads $900
AVO TMIC $800
Hyperflow CAI $380
PSR Turbo Inlet Pipe $250
Flash tune plus re-tunes $1500

Total Cost : $5030
Total Gain over Stock: 51 HP & 108 Nm
Difference in the way the car drives: Priceless
