We devoted additional time to fine-tune this exhaust note to sound terrific on a stock vehicle AND an aftermarket ECU tune. Many thanks to both of these owners for their assistance in Borla R&D. Please contact Harold in a week regarding availability.
Regarding the fins, stay tuned for more details on our (optional) exhaust-diffuser component...
Those fins look amazing; we need more details!
