This is a DIY 3" exhaust kit for 1991-1999 Tercel & Paseo! It starts from approximatly from the cat location. The kit does not a bolt on, the hangers will need to bent & welded in place along with minor trimming of the tubing to allow perfect fitment to your car. We use a Jones MaxFlow muffler for the ultimate in flow with good sound control with a great tone. The tubing is made out of aluminized steel for ease of use & durability. The clamps are Accuseal units.
