Hello everyone, I've returned from an extended period of 'leave' we'll call it. Sadly, my poor beast was written off last week due to my over zealous right foot (after not driving for about 7 months). So I've decided to join the dark side, and cash in some of the insurance monies after...

Sorry to say but sounds way out. Make sure all your setup is correct. A 270rwkw SS manual has cannot physically pull that 0-100 time. Also set the car up as an 09 Pontiac G8 GT it has the closest PID specs to our car.

I bought my cousins one from Joondalup exhaust in Perth. Quick (and free) delivery and no damage. His was stainless steel also, total cost was $1850 delivered. Give them a buzz, they don't talk **** either. Will give you good advise based on what you want.

Manta is a genuinely good brand, IMO second only to Difilippo for our cars. X-Force is ****, don't waste your time and money. If you don't want drone go with the option they suggested. That being said and sorry to add confusion but I bought my cousin their 'loudest' 3" setup for his auto VF...

I saw my first one on the road yesterday. Gunmetal grey redline, looked like it already had aftermarket wheels (5 spoke black of some sort). Looks really good with the new tail lights and bonnet vents/front fascia design! Also rear brembos - win.

Your local exhaust shop should have some

I had same parts as Walkinshaw use and a tune, highway economy went up by 1L/100km but urban went up by over 6/100km. Sounded tuff and went very well.

Yeh motor mag had the Clubby on it at 395kw also.

I've got the same noise, it's just because the FE3 suspension is quite stiff. Nothing to be worried about.

Oh blah blah blah! Haha, supercharging my SS was a terrible idea! It's still way slower than the M4 and uses literally more than twice the amount of fuel it's shocking. But fun. Will be good to see the GTS-R doing some track work like it's built for! I'll finish with S55B30 > LS9, LT4, LS3...

Precisely, spend $4k on a second hand VF GTS and you'll have more power than the GTS-R LS9 and with my flame suit ready 'a more streetable' setup. But, with the LS9 Camshaft & 2.3L blower it could easily spank a bolt on + tuned LSA. That said, it's not really the point of the GTS-R. It will be...

If I were you I would wait and buy something decent, like Difilippo or Manta.

C&A Autofashion, HPF or autotechnique

Mate you pay for what you get. If you buy cheap **** you'll get cheap ****. Save up and buy something decent. Also worth stating what your budget is.....

Thread title should read: "Xforce 2.5inch exhaust is ****"

Walkinshaw is just a difilippo exhaust with a VCM OTR intake (if you option it, otherwise you get a side mount enclosed pod filter intake). Harrop is pretty good except their extractors are far from 'tuned length' as advertised, sounds nice though. Best bits would be Difilippo exhaust and...

Most people prefer to run shortened shocks with superlows. I run king spring lows with my redline and haven't needed to change anything. Go to the myrides section for VF, you'll find a few people with SLs (or Pedders SL equivalents) with shorterned shocks.

Howdy, It's just valve train noise and injector pulse nothing to be worried about. L77s are noisy engines.

Alternatibely sell the xforce and buy a full Difilippo system, or Manta they are the best.

How does your car handle the E-Flex variation in ethanol rating? I thought it was purpose built for E-85.

Do you run E-Flex or E-85??? Oh and BP Ultimate for me...

The SV6 comes with a cop chip which makes another 25rwkw, couple that with the performance enhancing chevy badge and you're looking at a whopping 35rwkw over the standard 3.6.

I would suggest you speak to VCM.

Difilippo is the way to go

Search for it pony, it's literally the first search result.... https://youtu.be/MMHbKQ2RLQc

Well clearly my advice wasn't taken.

Best option would be 2.5" 4 into 1 primary headers into a 4.5" collector stepped down into a catless 3.5" straight through system.

It will sound like a lawnmower.

VCM/Autotechnique Autotechnique - Holden Upgrades, Log Book Servicing & Dyno Tuning Google should be your friend.

Here you go. GM Confirms ZL1 Powered GTS

Bump - buy it.

GMH have put in a requisition for 300 LT4 motors, seems the limited edition Gen F GTS series 2 will have some extra ponies.

L77 in a nutshell

They're noisey engines mate, mine did the same thing. It got louder after changing extractors, I believe it's just valve train noise.
