Notes

Must use 2 1/4 in. offset inlet/center outlet muffler. Long wheel base models only. Will not fit stock exhaust manifolds that exit straight down. Wheelbase greater than 132 inch will require tailpipe extensions to provide proper tailpipe exit.
Some parts are not legal for use in California or other states with similar laws/regulations
