this looks interesting - do you have a comparison (fly by or on car) while driving of a stock gt3 with the silenced and non silenced versions?

Also, what is the approximate lead time for them delivered?

I ordered one. Will post some pictures and video once it arrives and I install it. I have the valved Fabspeed side delete pipes and I am curious how well this will sound.

Lots of media coming, we've been so keen to get customer parts out we have some what sacrificed our own marketing material so its a little back to front in this regard but needless to say we will be focusing on creating some really great and representative video to capture all of the different configurations under differing driving conditions

We are currently running around 2 weeks away from point of order to delivery however it'll not be too long until we have a good inventory of stock items in which case delivery world wide is usually within 3/5 days depending on location

Very much looking forward to hearing your thoughts on the system!

No, non-silenced. I think the car sounds soft even without valves open. So want a little more sound with valves closed in addition to open.

The very popular Sharkwerks T304 Bypass without tips is $1500 USD, our price is right around 20% more for a ‘comparable’ product.

The GRP bypass which includes tips (albeit integral) comes in at $2300 USD, again T304. Our ‘comparable’ product is just over 10% more expensive.

Now, when you consider the price of the base material, T304 vs KS TI-1.2 ASNEX and also add the significant difference in man hours required for construction (all here in the UK) then I’m sure you’ll come to the conclusion that our prices are extremely competitive for what we feel is a superior product.

Can you elaborate on the difference between using titanium construction vs the T304 steel often used by other bypass manufacturers? From my understanding you are the only one to offer titanium for center bypass other than Akra (I could be mistaken). I'm definitely interested in your titanium non-silenced bypass, I like that OEM tips can be re-used & the quality and attention to detail looks great (looks cool heat cycled), waiting for more videos to come out to hear more sound comparisons

Material to material for the exact same part and wall thickness the Titanium part will weight around 40-45% less than the equivalent T304 steel part. Obviously reducing weight is a huge factor especially given its hanging off the back of a rear engined car, with this in mind Titanium for us is the logical choice of material. We also go lower on the gauge of the material than most do with T304 so the weight saving is even more dramatic.

The other difference is the specific hardness of the two materials. Due to this difference Titanium has quite a distinctive resonance which helps accentuate the tones which many of us love.

We designed all of our parts to be modular and work together with OEM and/or aftermarket. We appreciate that sound volume and quality of sound is very subjective and want to give our customers the best possible number of options to achieve the best solution.

Expect a whole lot more video and media to follow soon

Interested in this exhaust. I am surprised how tame the exhaust is below 4k rpm. My 991.1 c2s with pse sounded so much better at the low rpms.

Our non silenced plus tips would most probably be the solution for you if you’re looking for some more sound with valves closed and even more again with valves open.

The OEM exhaust especially with valves closed is almost silent!

You could also disconnect the factory valves and run valves open all the time if you’re keen to have some more low down / idle noise.

That is true, but it also comes with a (for me) almost unbearable drone at 2000-3500rpm part load. Does any of your set ups mitigate that?

Drone with the 100% OEM exhaust with valves connected? Just to be sure before I expand on the differences.

Exhaust noise / tone / drone is of course a very subjective matter so without hearing / experiencing an exhaust in person it’s undersanably difficult to properly describe.

Please post up pics once installed. I am very interested in this product and like the titanium for weight and sound benefits.
