Why this downpipe is important?:​ 1.) Guaranteed No CEL ( 5" GESI EPA certified catalytic converter). 2.) I wanted a freer flowing exhaust. 3.) I wanted the sound that this should produce to emanate from the economy L15. 4.) This design is similar in characteristics to the PRL that has been discontinued. 6.) Solid platform for any additional modificationS that are made to the vehicle. 7.) Replaces the gaping hole of PRL pulling out of the market. Downpipe was well protected and shipping took two (2) days to get to my location. Nothing appears to be damaged and came delivered via FedEx. The package contains the downpipe, bolts, nuts, gaskets, wiring extension and TSP sticker/decal (At least 5+ HP).
