Nice job! That should be plenty big enough. My setup has a vacuum canister which helps with volume. I'm not sure if you said you have that.

When I bought my used npp mufflers they came with the factory solenoid, canister and rear tubing. I plumbed into my brake booster and ran the tubing inside the torque tube tunnel front to back. I also ran wire to the solenoid for a switch I mounted in the drivers knee bolster.

Oh thats what you meant... . I bought the NPP in a kit all in one. Came with the vacuum lines and wireless remote. I ran my tubing down the passenger rocker panel this way no engine heat on the tubing.

Glad to hear you were successful. Yes, that hole is plenty big enough.

Mufflers installed at a shop today finally...Damn now that sounds more like a vette .. .. Brought her home, now just have to install the vacuum hoses on the muffler actuators and all is done.
