Would there be interest in an affordable Valvetronic Exhaust? GROUP BUY OPENED!

Bomiz · 05-20-2018, 10:37 PM

been talking to a few manufacturers. this one I like is pretty busy and would be able to build a sample in 2-3 weeks. if all goes well, it'd be very affordable.

I'm going with an electronic valve only instead of the vacuum option.

How much would 'very affordable' be?

I would have to wait and see the pricing depending on quantity. But I would assume around $1500

Just paid to have the same produced. Should be completed in 15-20 days.

I have the Evolve valvetronic and although it sounds wonderful with valves open and closed and has zero drone over 2200 rpm, it isn't loud and I always drive with it on loud.

I'd like 'loud' to be 'loud'.

The current Z06 is completely quiet with the valves closed, yet when open it blows your ear drums out with pure glorious v8 sound

well it could be dependent on x pipe and catless or not also. I'm trying to get a good balance with stock x pipe, but have it really open with an x pipe

Correct

I have the evolve valvetronic paired with the ess hfc xpipe which has 2 hfc and 2 resonators

Exactly. And this is my custom RPI x pipe with multiple resonators as well.

Going to order and try 76mm Tips and 89mm tips to see which fit better.

Bomiz · 05-28-2018, 01:14 AM

Talking to all these manufactures, it's funny to see the branded products of companies we all buy from as samples

Bomiz · 06-02-2018, 03:23 PM

Ordered 2 differently designed samples for testing. Should receive in maybe 2-3 weeks

TRUE2THEBLUE · 06-03-2018, 12:37 AM

Excited!

For people curious. I'm doing an Electronic Valve and not a Vacuum Valve. Vacuum valves are actually cheaper. And you'll see that the electronic valved exhausts on the market for our car are using the more bulky electronic cutouts (Meistershaft & Evolve). This will harbor the newer ones that look much more flush with the piping

might be interested

The thing is I'm going to need to test fit on an E90 so maybe that might make you interested haha.

happy shifts · 06-04-2018, 10:34 PM

Definitely interested for $1500

Bomiz · 06-05-2018, 07:38 PM

Do you guys know if 89mm tips will fit with a diffuser? I'm opting to test the 76mm tips, but maybe get a set of 89mm to see if it'll fit

89mm is WAY too big.
The biggest I know that could fit are 80mm if you stack them side by side with a diffuser.
My friend with a Gintani exhaust had to get rid of his diffuser because it wouldn't fit.

Yeah that's what I thought. Problem is the 80mm and 83mm tips are hard to find because it's an abnormal size. And to make the exhaust still affordable you don't want to spend a bunch extra on making perfect tips

Have the shop that's fabbing the exhaust for you to do matching tips.
