The LC Pro Flow Exhaust System is designed to fit the 1986 to 1995 Toyota 2WD and 4WD trucks with a stock exhaust system or LC header kit with the hanger in their original OEM locations.
Installation: Remove the stock exhaust system from the catalytic converter on back. Be carefully not to damage the hangers or brackets.
Install the Pro Flow Exhaust System in the following order. See attached diagram.
- Install the S pipe into the muffler and place the muffler in the stock hangers. Install the clamp snug, do not tighten firmly.
- Attach the tailpipe section using a 2-bolt flange gasket. Bolt to the muffler and attach rear hanger. Do not tighten yet.
- Check alignment and location of muffler and tailpipe. Hangers may require a slight adjustment for proper alignment.
- The front pipe section will need to be cut to length. Be sure to allow enough overlap for adequate clamping area. Install the front pipe section using a 2-bolt flange gaskets. If you have to cut the front section of pipe, make sure its cut clean (no burs) and cut straight.
- Check the clearance of your Pro Flow Exhaust System to the floor pan, chassis components, parking brake cable assembly, driveshaft, etc. Adjust system as needed.
- Starting at the muffler, tighten bolts working towards the front and back, then firmly tighten the 2 1/4 exhaust clamps.
- Start engine and check for exhaust leaks. Tighten flanges and clamps as needed.
LC Engineering recommends using O2 safe, high-temperature silicon on slip connections for small exhaust leaks.
**Note: This system is designed to fit Long Bed - Extra Cab Trucks, as well as Short Cab - Short Bed Trucks, FRONT PIPE SECTION WILL HAVE TO BE CUT to correct length for Single Cab Short Bed Trucks.
