The results are obvious.

Cars with stock exhausts require lots of unburnt fuel to make any noise. This is in the region of what we consider excessive.

Cars with Akrapovic exhausts - will make some noise but the exhaust really does absorb too much sound.

Evolve E-Tronic valve closed - very little effect, again too noise absorbent.

Evolve E-Tronic valve open - lots of noise on the over run and very deep (due to 65mm straight through to tail pipe design)

Eisenmann Race, Gintani Race, Active, Innotech (Valves opened) with HFC and resonators - a good amount of noise

The above exhausts with CATLESS with or without resonators in the X pipe - lots of noise on the over run.

Yet to try the stock exhaust modded but given it's path it should make a lot of noise too.

This really does turn the driving experience into something else…. as experienced by us too on a daily basis :-)

I wonder how it's like with my full supersprint race, i wish i opted for this feature

Need to get a video of that

E92cannon · 05-20-2014, 05:06 AM

I can report some flames at low speed. was going through a village at 20-30, was half throttle in 2 gear (dct) and let off. Mate behind me saw two small flames.

Now that the weather isn't blistering cold here, I can finally get my exhaust hot enough to hear some machine gun overrun. But now I want fireballs like you guys, LOL.

E92cannon · 05-20-2014, 08:04 AM

Im running a fully catless x-pipe maybe thats why

edwinm3 · 05-25-2014, 03:50 PM

I was beating mine up yesterday at the track and it was popping and cracking all day lol. Sounded bad ass every time I downshifted.

E92cannon · 05-26-2014, 04:03 AM

My car popped very loudly if you give it 50-60% throttle to 4100rpm then let off. Was giving lovely blue flames last night. I really need to get a video.

You do!

INNOVATE_1 · 05-28-2014, 04:55 PM

This will definitely add to the fun...

dmk08 · 06-02-2014, 12:26 PM

I've pretty much perfected the flame shooting with a DCT. Get the car nice and warm, come off the throttle in 3rd gear at reasonable high rpm and blip it down to 2nd hitting 4500+ rpm in S3/S4 without any gas and you should get a nice pop/flame.

terahertz · 06-02-2014, 07:53 PM

Would an Eisenmann Sport be too quiet for the pops? I have catless x pipes.

I believe the catless x pipe is the important part.

Definitely not. As others have stated the catless X Pipe would be key in your set up.

RL_M3 · 06-13-2014, 10:36 AM

Will i get flames with catless primarys and a Meister GT2 rear? If not i may have to get a full x-pipe. Thanks All!

Not tested that particular set up so can not be sure. You could always try it with your current set up and then go full X Pipe if you required.

gnoy26 · 06-29-2014, 09:30 AM

nice!

aus · 06-29-2014, 09:59 AM

Just to clarify, an Akra EVO will not do much burbling or flame throwing??
