Same American Thunder build with black ceramic dual 4.5-inch tips, rear exit only - this is the only Flowmaster cat-back that fits the PowerBoost hybrid.

why this one — Flowmaster claims up to 18 hp and 14 lb-ft on their own dyno, and it's the only Flowmaster option that fits PowerBoost trucks - no independent dyno confirms the number.
