C8 Corvette Grand Sport Borla S-Type 140838BC with NPP Exhaust - Black Tips

Borla 140838BC Cat-Back Exhaust for the 2027 C8 Corvette Grand Sport, Black Chrome Tips The 2027 Grand Sport leaves the factory with bright exhaust outlets set into a wide rear fascia, and this is the Borla that turns them black while leaving the note composed. The Borla S-Type 140838BC is a cat-back exhaust for the 2027 C8 Corvette Grand Sport and Grand Sport X and their 6.7L LS6 V8, finished with four inch black chrome on T-304 stainless steel tips in a dual split rear exit. Dark tips against the body color are the whole point of this version. The 140838BC replaces the exhaust from the catalytic converter outlets rearward in one complete system, with 3-inch main piping and 2-inch and 2.75-inch sections through the middle of the car. S-Type is Borla's balanced sound level, a powerful and deep tone shaped by SwitchFire and the Polyphonic Harmonizer, the two technologies Borla names on this system. Your quiet mode stays exactly where it was, because AFM/DFM valves and NPP valves included in the kit connect to the factory actuators, so the Grand Sport keeps the behavior it left the factory with. Both valve sets are in the box, along with the heat shielding, so nothing on the car has to be sourced separately to finish the job.

There is no published decibel figure for this system and we do not estimate one. What changes visually is immediate. The tips read dark from behind the car, and on a Grand Sport that difference lands across a wider fascia than on any other C8 this system is built for. It is the first thing anyone behind you sees. The tips ship on the system, so there is no separate tip kit to order and no waiting on a second part to finish the car. One job is not finished when the exhaust is bolted up, and it is covered below. Important Exhaust Notes This fits the Grand Sport built with the factory NPP valved performance exhaust. Do not install it on a car without O.E. NPP. The quad center-exit exhaust is a different car. That layout is the optional RPO WUB and it is standard with the Z52 Track Performance Package. No cat-back is published for it. Check the window sticker before you order. Valve actuator recalibration is required after installation, per GM Document ID 5406413, and a Chevrolet dealer is the recommended place to have it done. Plan for it as part of the install.
