Attachment 1 Graham Rahal Performance Chalk Porsche 991.2 GT3
Center Section Exhaust & Roll Bar Safety Package Install
Desired to do a little tracking, Tom in Indianapolis called Graham Rahal Performance looking for a street performance package for his GT3. Partnering with us here at BBi Autosport, Graham Rahal Performance installed the short list of upgrades below to improve overall handling but keep it comfortable and usable as a daily in the nicer Midwestern months!
- BBi Roll Bar custom powdercoated to match the yellow brake calipers
- BBi Sub-Belt Brackets
- Schroth GT3 racing belts in black with the normal Yellow lettering that sets off just perfectly
- Custom Seat Cushion upholstery to allow the Sub belt to pass through
- Custom Street Cup Alignment
- And of course the mandatory GRP Center Bypass Exhaust!
GRP Porsche 991 GT3 / GT3RS StreetCup Center Section Exhaust
Made in the USA, this Co-Branded Center Section Exhaust is TIG welded out of brushed T304 stainless steel and features the main pipes merging in the middle to function as an x-pipe. By retaining stock side mufflers and valves, the factory "sports button" feature is kept to conveniently switch back and forth between the aggressive "sport" mode during spirited driving sessions and the quieter, more civil "non-sport" mode for minimal noise on the highway.
