Billy Boat Cat Back Exhaust w/NPP - Chicago area

SOLD

Hi, I have had this stored away for about 3 years now. I had it on my 2017 SS 1LE for about 5k miles before selling the car. I kept it with the intention of getting a ZL1 1LE, but covid hit and car prices went crazy. I never got the ZL1, and no longer see that happening in the near future. It's time to consider parting ways with this exhaust so that someone else can enjoy it as much as I did.

Here's the details:
3" system with 4" tips. NPP function.
This was approximately 40-50lbs lighter than my stock suitcase.
Front pipes: PN: FBOD-0735
Cat back system PN: FBOD-0731
Fits the SS 1LE and ZL1 with manual transmission.
Total cost was around $2,800
Asking $1500 local or $1,750 shipped.
Located in Shorewood, IL

This is the best sounding exhaust that I've heard on these cars (personal opinion i know). My next fave is Corsa, but this is all the sexyness of that raw sounding exotic note with a bit more refinement. The build quality is the best that I've seen. The welds are beautiful. The NPP system is robust. It's a handbuilt work of art unlike the mass produced systems.

The only downside I ever found with this system was that the NPP system could have been more effective. Even with that being said, the NPP valves do a measurably effective job of reducing decibels, as I did a test on this at one time. I never even cared to reduce the amazing sound from the system, so I didn't use NPP anyways.

Am I asking too much or is there no love for Billy Boat?

Any photos of it on the car? Also I'm not familiar with aftermarket NPP, does it retain all the modes or is it just a two position system?

Aftermarket NPP systems typically retain stock actuators (those black boxes attached to the exhaust) and supply only the physical rotating valve bodies, so I'd think they also retain stock functionality.

The electronic actuators bolt right up to the valves and work just like stock.

Sexiest exhaust on the market. Almost 50% of the normal price. Where is everyone at?
