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.

Exhaust system
I was surprised of the quality and the overall appearance of this product

Great Company That Stands Behind Their Product
I bought this "direct fit" system for my truck. I had priced custom SS exhaust locally and had estimates from $800 to $1200 and it wasn't as nice as the LCE system. It's SS AND it's ceramic coated. Hopefully, this is the last exhaust I will ever have to put on the truck. I encountered a few problems and LCE made it right. Knowledgeable staff, customer focused. Will buy from again. The system adds power to the truck and sounds incredible.

Must have Exhaust System
Great product with great results, a must add on with their Street Header kit. All parts are bolt on and sits in the OEM placement perfectly. Big difference in power gains and sound on my 85 2wd pickup.
