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.

Parts came well packaged and in great condition. System went in with ease, had to perform a few minor modifications, but nothing crazy. Took the original toyota header off and put a LCE pro header on with the magna flow exhaust and the difference was night and day. Should have done this years ago. Not to mention, the exhaust system provides a great sound.

Quality exhaust for a fair price.
Exhaust arrived very well packaged, as I expect from a company like LCE. I've ordered many products over the past few years, and its been the same story over and over again. The Exhaust comes as expect, with instructions detailing the install. Yes the instructions could always be a little more detailed, but it only took a few minutes for me to figure out where to begin, and then I was off and running. Only thing I recommend is buying some permeated high temp grey for sealing the muffler ends to the other pipes, as it is cut to allow for a slip to slip connection to other pipes. Exhaust took a few hours to install from start to finish. Great sound, been installed for almost 2 months now. It may offer an increase in power, but I installed it for a nice sound, and because my other exhaust rusted off. Thanks LCE Performance!

Sounds good
Would be great if there was maybe just a little more instructions. It was great and has definitely helped my trucks performance and sound. I loved it. My only complaint is that for buying this product, header, and cat there was no stickers.
