Exhaust valve control system

[BippuALK]

I own a 1991 ls400 and I’m looking to redo my exhaust system with a valve control system that’ll allow me to adjust the noise level of my exhaust. I’ve looked at the qtp lowpro as I eventually want bags to be lowered and don’t want it interfering with it. Any suggestions as to what would be the best way to go about this?

Who's doing the exhaust work? If you are taking your car to an exhaust shop, you should check with the owner to see what he recommends. Many custom exhaust shops have installed all kinds of configurations, including muffler bypass kits.

I’d be doing the work myself. I’ve done welding work in the past and I’m not horrible and can get by
