Pro Flow Exhaust System
LC Engineering’s Pro Flow Exhaust Systems are made with 409 stainless steel tubing, a 409 stainless steel straight-through Street Max muffler and 3/8" thick mild steel flanges. The straight-through design of the Street Max muffler delivers a deep performance tone without the excessive interior drone or high-pitched external sound frequencies (rasp) while providing optimal flow for improved horsepower & torque. They are then ceramic coated for long-lasting good looks and protection from the elements. LC Engineering designs our kits to be a direct fit application that requires little or no modifications and uses factory exhaust hanger locations. This bolts up behind your factory catalytic converter or one of our high flow performance catalytic converters. This exhaust system features 2 1/4" tubing with a 3" polished stainless tip. Every kit is shipped complete with all the instructions and hardware you will need for a quick and easy installation process.
Features:
- Straight-Through Design
- 409-Grade 16 -Gauge Stainless Steel Construction
- Delivers A Deep Performance Tone
- High-Heat Thermal Mesh
- Improved Horsepower & Torque
- Effective Drone Reduction
- 3 Year Limited Warranty (Muffler)
NOTE: LC Engineering does NOT recommend wrapping our headers with any sort of exhaust wrap. Doing so will increase the likelihood of a premature failure of the header, as it holds contaminants to the exhaust tubing and increases the chances of corrosion. Exhaust wraps will void any and all warranty claims. Will not fit 4 Runners, no company makes a cat back system for 1st Gen 4 Runners. You will need to have any exhaust shop build something directly to the vehicle.

Installation:
-
1. Remove the stock exhaust system from the catalytic converter on back. Be carefully not to damage the hangers or brackets.
2. Install the "˜S' pipe into the muffler and place the muffler in the stock hangers. Install the clamp snug, do not tighten firmly.
3. Attach the tailpipe section using a 2-bolt flange gasket. Bolt to the muffler and attach rear hanger. Do not tighten yet.
4. Check alignment and location of muffler and tailpipe. Hangers may require a slight adjustment for proper alignment.
5. The front pipe section may 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 it's cut clean (no burs) and cut straight.
6. 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.
7. Starting at the muffler, tighten bolts working towards the front and back, then firmly tighten the 2 ¼" exhaust clamps.
8. Start engine and check for exhaust leaks. Tighten flanges and clamps evenly as needed.
NOTE: This system is designed to fit all cab and bed configurations. FRONT PIPE SECTION WILL HAVE TO BE CUT to correct length shorter applications. LC Engineering recommends using O2 safe, high-temperature silicon on slip connections for small exhaust leaks.

Spectacular Fit and Finish
I have been working on Toyotas since the '70s. I have gotten used to having to cut weld patch and fabricate to get exhaust "kits" to work. This exhaust took none of that. All factory hangers and mounts lined up, there were no clearance issues, the hardware was present and fit properly, gaskets were included. Truck had the CAT welded in place, LC supplied an extra flange that also fit perfectly. The truck's owner says that she couldn't pull hills here at 7000' feet in 4th gear at 75 mph prior to my installation of this exhaust. Not only does this exhaust fit, look and sound great, made me look good too.

Best Exhaust for your 22R
This is the best exhaust system for your 22R hands down. I have never installed an exhaust and this bolted right on the truck. Just used a bandsaw for one cut, one simple cut, to fit the catalytic converter. Love the sound and definitely feel the power difference. Best investment I have made. Great quality, I can’t wait to enjoy this for decades to come and pass on to my boy in about 14 years
