Stillen headers, BERK cats and HiTech system fitted

BGTV8 · 04-24-2010, 03:46 AM

After some research and experimentation though the last 10 days, I now have my extractors and hi-flow metallic substrate cats fitted, with a HiTech system behind it.

We experimented with a mild-steel system, but rapidly came to the conclusion the purchasing a specifically manufactured system was the way to go. Looked at modifying an X-Force 350Z system, but again came to the conclusion that the HiTech system gave us the best "fit" - in fact, it bolted straight into place with an absolute minimum of fuss.

Work was done by Tom Harding at Carline Exhaust in Ballarat - he does a lot of custom hod-rod and race car systems and he has done a beautiful job.

Am taking the Z to the MSCA Philip Island sprint on 30 May to give the car a little spanking - it already knows its way around Sandown. I'll be fitting my DL-1 data logger if I can find an ECU wiring diagram between now and then, otherwise I'll onlly be able to log track position (lateral and longitudinal acceleration), speed from the GPS and brake (take a pickup from the brake light circuit). If I can splice into the ECU, I can log 16 digital channels and 8 analogue - but not sure what use these will be on a digital vehicle).

Congrats mate. Do you have any dyno charts or videos yet?

And how's the drive? and the sound?

Car is improved, but only modestly - certainly accelerates more quickly and the note is now audible (I purchased the quietest of the 3 systems available). It is quite harsh when started from cold as the ECU holds the engine on fast-idle at 1400-1500rpm, but is OK as soon as the temps rise. The system seems to have improved fuel economy .. I am a fairly sedate driver on the highway and regularly average 10l/100klm driving from NE outer suburbs (Warrandyte) into the CBD on Eastern Fwy and back each day, and driving back from Ballarat last weekend netted 9.1 l/100K - which I thought was an interesting outcome.

There is a distinct change in exhaust note above 4000rpm all the way up to 7500rpm when the engine "sings" (a better word is it "wails") - reminiscent of a flat-plane crank V8 sports car I drove many years ago (sounds like two 4-cyl engines joined together). Gave the car a blat going thru the Eastlink tunnel on Saturday that brought a smile or two.

Runing the car up thru the gears, the top-end is noticeably improved - due I guess to better top-end breathing - may be further improved with flat-panel (K&N etc) or maybe pod filter , and may do that in due course.

Have not yet scheduled a run over the rollers ... will do so in the next couple of weeks if I get the chance, but life is very, very busy at present (day job from 07:00-19:00 and weekends taken up with race car prep for Vic State Circuit Race Series). Will post a dyno shootout mode graphic if/when I get it done.

I don't own a cam-corder so a video is problematic (and using a digital camera to grab a clip wont really do the sound justice). If anyone is planning on being at Philip Island on 30th May, I will be there to give the car a spanking, so bring your video camera and we may get somehting that can be posted - but it is a few weeks away.

The real test will be at PI when I can open the car right up - too risky these days to do so on the open road given the state of legislation we have to deal with in Vic at present ....

Was it worth it - absolutely .........

Sounds like the mods are doing awesome. Just wondering with doing CAT,headers, exhaust and POD if the engine would run lean without a tune. I would love to hear your setup in person, not sure about may 30th but i'll try another time when i get my Z (if that's ok with you). BTW did you import the berk cats from US?

BGTV8 · 04-28-2010, 07:11 PM

Stillen headers and Berk cats imported from ImportPartsPro in Texas. Prompt service via US Post priorty parcel post .. door to door in 5 days. I have some concerns about the ECU throwing an engine check light based on rich-lean codes, but will cross that bridge if and when required. I had to fit an interceptor piggy-back in my STi when I had that, so its a problem that is relatively simple to resolve ...

do you have the website of the hi-tech exhaust?

BGTV8 · 05-14-2010, 06:15 AM

Go to

HiTech Mufflers

They are located in Sydney but the shop that fitted everything up for me had a system the day after they ordered it ... quite impressed with their level of service actually.

I have had the system instzlled for 1500klics so far and no sign of an ECL at all ... really happy .... now to give the car a spanking at Philip Island at the end of the month !!!
