This PowerFlow Dual Stack Kit is a full 4 Inch diameter under the bed with 5 Inch diameter from Y-Pipe to the base of the stack tip in the truck bed. Grand Rock’s kits were designed as a “No Muffler” exhaust system and feature AccuSeal clamps for superior joint sealing. Grand Rock chrome stack tips (Sold Separately) are 36 Inches in length and feature high quality triple chrome plating for a killer look that lasts. For reference, a 36" stack will be about even with the top of your truck cab. Taller 48 and 60 Inch tips are also available. Please call for pricing. Other manufacturer’s stack tips may not be compatible with Grand Rock’s Y Pipe kit. The stack tips used must have a 5" O.D. bottom.
Chrome 5 Inch Rain Caps for straight-cut stack tips look sharp and keep the rain out. To protect the contents of your truck bed, choose from MBRP stack in-bed diamond-plated covers or Grand Rock chromed T-Pipe Heat Shields, each sold separately.
