Add exhaust valves to aftermarket exhaust

[InvestorZ_GT2]

I was wondering if I have an sftermsrket exhaust and want to add valves to it. Where would I get them? I haven’t found anyone besides stainless bros with them. They say it meant for their exhaust. Anyone have ideas to help that would be great.

You could try this mob. Don't know anything about them

Stinger Bi-Modal Exhaust | Lumen

The Stinger's Bi-Modal Exhaust System combines premium hardware with intelligent electronics. Drivers are able to select from various driving modes such as eco, comfort & sport. The system controls sound output so that when in eco mode the exhaust is more or less silenced and when in sport mode...

You could try your local Kia dealer and buy genuine rear mufflers with valves attached

They are more than $2300 each here

Part Number 28710L
Part Number 28711R

I might add that there was a Bi Modal kit available from Kia dealers here for around $2400 but I haven't seen it for a while so whether it is still available here or there is debateable

Or, if you don't care about your stock exhaust . . . maybe cut out those valves and re-weld to new exhaust?

If you are talking about adding vales to your existing mufflers that have no valves, then I think a reputable muffler shop might be able to do that for you. Honestly, not sure I would go that route as that might not be the most optimal for performance as your current mufflers are likely not designed to have valves. And that even won't be necessarily a cheap job to do either. Cutting up your stock exhaust and taking the valves over to your current aftermarket is an option but that's if it will fit.

You could also just get valvetronic universal valved mufflers for $600 that comes with the control unit call it a day, if you don't want to spend 2K+ on a catback.

My car has the valves already. Just not sure if I want to cut them off. Having 2.4 high flow cat from NGT and Jun bl racing exhaust it’s going to be loud. I also trying to find tips for exhaust but the diameter is 60.5mm. If I can Theo let of a tip at 63mm which is 2.5. Will those tips fit over a 2.5 inch pipe?

Just put them back on.

If you really want to try others though

The GM Chevy V8 which is the VF Holden Commodore SSV here exported to the states had Bi Modal valves.

Go to a GM dealer and see if you can buy them as parts

or these. Know nothing about them.
