To unleash the beast within the Grand Cherokee's SRT-8 Hemi, Billy Boat Performance Exhaust hand built this performance exhaust system entirely out of T-304 stainless steel tubing, and TIG welded for unmatched beauty and craftsmanship. While other's claim to build performance exhaust for the SRT-8, B&B builds the SRT-8 system out of 3" tubing for increased flow and performance. The system also uses B&B's proprietary Purge Resonance Technology to eliminate in-cabin, low frequency resonation, and a front xpipe section for a smooth, even flow. The result is a truly spectacular muscle car bark at idle and under acceleration, while providing a smooth, understated tone at cruise.

We worked hard on the sound, but we did not forget about the performance. Every B&B system undergoes complete testing on our in-house DynoJet chassis dynamometer. The exhaust made a difference of 17 horsepower and 21 foot pounds of torque measured at the rear wheels. The system is finished off with a pair of B&B's 4.25" double walled stainless steel tips and it is completely polished. Take it out of the box and you won't know if it goes under your car or on your mantel!
