Turbo Back Exhausts w/ choice of Helix Catted or Catless DP:

Helix Catless Downpipe 02+ WRX/STI


The Helix Downpipe is the optimal downpipe for the performance minded Suby owner. This downpipe features a cast bellmouth which provides the absolute maximum exhaust flow and minimum back pressure by allowing the wastegate gases to exit without disrupting normal exhaust flow. The piping is full 3" Stainless Steel (304) polished, and the package includes gaskets & bolts. This downpipe replaces both cats and is designed for USDM fitment only. The combination of the Helix uppipe, downpipe, and exhaust system will yield 30+whp!

Helix High-Flow Catted Downpipe 02+ WRX/STI


The Helix Catted Downpipe incorporates Helix Power’s first-rate bell-mouth downpipe, with the addition of a 200 cell Metal-Substrate high-flow catalytic converter and thermal barrier heat-shield. The 200 cell Metal-Substrate downpipe has been tested by us to yield 7-10whp over the factory twin cats, while able to pass stringent California smog standards on the WRX / STI. The thermal barrier heat-shield assists in rapid warm-up of the cat for maximum efficiency and helping to reduce engine bay temperatures.

Tuning Solutions:

And if you consider your engine a worthwhile investment (which I think most of you do), you might want to consider this little insurance policy:

An extremely valuable tuning tool and problem indicator, the Link Knock Link w/ Bosch Knock sensor is a critical component for the highly modified engine. Highly modified engines run the thin line between peak power and engine failure. This failure is often caused by detonation. The Knock Link uses a highly sensitive (and superior) to stock) Bosch knock sensor that is extremely sensitive to detonation. The Knock Link alerts you the moment detonation is occurring; not after you've finished looking at your data logs or blown your motor. The Knock Link can protect your motor while tuning or simply when you get a bad tank of gas. It is our opinion the Knock Link belongs right next to the Wide Band O2 sensor and is a necessity for the highly modified engine; think of it as cheap insurance to protect your high performance (and expensive) motor.

-Monitor real-time knock.
-Optimise advance.
-An excellent saftey measure for heavily modified engines




We are offering the following package:

-Cobb Accessport
-1 Custom Map for your car tuned by Mike (must be standard bolt on modifications)
-Link Knock Link
-Bosch Knock sensor
-Installation

$1099 Installed for WRX
$1149 Installed for STi
$249 Shipped for just the Knock Link and Sensor

 

Porterfield R4S Brake Pad Install Specials

04+ STi - F/R - $449 Installed
03+ WRX - F/R - $349 Installed
02 WRX - F/R - $329 Installed

- Includes rotor turning
- Ideal combo street / track pad
- Carbon Kevlar pads

These pads are an ideal balance between race pads and street pads. The Porterfield R4-S’ are unique because they’ll withstand 20 minutes of track time with no fade (they so not fade at temperatures up to 1,100 degrees F) but at the same time, they will work fine when cold and they’re very rotor friendly (as well as being very slow wearing). The R4-S friction level will give you an impressive increase in stopping ability with very minimum pedal effort. The R4-S compound also has the absolute lowest noise and dust levels, far below OEM equipment or any other high performance brakes material. Good for autocrossing, drivers schools, weekend track sessions, solo events, and rallys.

Hey Preston,

you have lowered your price on the Pink's installation to $509

STi Pink Springs - 04+ WRX/STI
$509 Installed!

Since I have an appointment this Sat., I should be getting the lowered price instead of what you have quoted me on the invoice of the spring, correct? I've not paid for the install yet so it's not like I'm asking for the refund for the difference so I hope you can hook me up on the lowered price.

Thanks. Emailed you.

 

hkwan - PM sent

Preston

 

Preston, I replied to your PM.

You've told me when I purchased the spring that it was a "install special" and I must get them installed at your place to get the OTD price. You are now telling me that the discount is on the parts and not the labor? Which is the case, preston?

These springs you are advertising are the same batch of springs you had when you first advertised, correct? Why can't I get the price match when I have not even taken delivery of either parts or labor? I can't understand this.

 

You have a PM.

Thanks,
Preston

 

Got your PM.

You have mentioned that it was Geoff that advertised this (even though you have signed this current advertisment) and not you. Well, I guess it happens in every company where miscommunication happens among employees. I understand, don't worry about it.

In anycase, since I only purchased this a few days ago and have not taken delivery on parts nor labor, how am I not be eligible for the lowered price? Just wondering how all this works.

Thanks for the help all along.

 

Henry - Got your PM, your refund will be processed tomorrow. Oh btw, sometimes Geoff posts and puts my name and vice versa.

Regards,
Preston
