Is there any valvetronic exhaust that’ll fit the 3rd gen Is350 Awd f sport? I heard about Gthaus but that price tag is way too pricey

I searched the forums and couldn’t find a sound clip of an Invidia axle back paired with a resonator delete. Let me know if you anyone here can post a link. Thanks!

 

There are not any mass produced valved exhausts for the 3IS that I am aware of. The only option would be to purchase a separate exhaust cut-out and create a custom system.

With that said, I'm not sure how much room there is under the car to run a secondary set of pipes along the existing exhaust if the goal is to have a straight piped section along with a muffled/resonated section.

 

Xforce makes one. I’ve seen the video on YouTube and it sounds really good. I just looked and I can’t seem to find the link. But it’s there... definitely check their website.

 

I asked them a while back and they said it's still a prototype. Didn't give an expected availability.

 

On there website they only have one for 2013 and older and for the F :/

 

It would probably save you a bit of money to have a shop make one from scratch.

You can use a pair of flowmaster super 44 mufflers with twin inlet/single outlet, use an exhaust cutout you can find on ebay, and have the rest of the piping run off of that. You can probably cut the flange of the existing muffler to mount to any aftermarket midpipe already available and just have the small run of piping to fabricate.

 

I installed a ECS Vacuum actuated cutout on the pipes of the ark axleback portion. I had to modify it a bit for it to clear the subframe.

 

Can you show us how it sounds and looks?

 

Sure, I'll try and make a video this week.

 

Here is a video of closed vs open valve. As stated in the video, the mic does not do it justice. Open valve is significantly deeper and louder.

 

You've got some slick videography skills dude.

Do you have a pic of where you welded in that cutout?

 

Thank you. I do videography/photography as my job. The cutout is a slip on. You could also put it in replace of your resonators. But that depends on if you want to get rid of them.

 

Do you think I could do the same on my invidia axle back? I'm about to pull the trigger on the invidia mid pipe as well but the idea of having it valvetronic would be sick.

Also, how do switch between open and closed? I assume you ran writing to the dash but can you tell me how exactly?
