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.

Awesome addition to the street header.
Added this to my truck as well as the street header. Nice quality product! Would highly recommend! The last portion had to be modified for my application. My springs would flex into the exhaust tip. So I cut and turned the last section upside down to point down to the ground. Might not look the best after modifying the last part to some but it sounds great!

I didn't know what I was missing
LCE is the best and the Pro Flow Exhaust System is awesome. I bought the Pro Flow Exhaust System and the LCE Street Header kit for 4wd. My 1994 4wd is flying down the road now and I got my low end torque back!!!!! I didn't know what I was missing until I installed everything last week. I had seen the kit in the catalog years ago and just didn't buy. If you are thinking about it you wont regret it. I sure don't. Five stars for quality, sound and fit. Thanks Bryan and Tony for taking my questions on the phone. I also have the double chain conversion kit but have not gotten it installed. Thanks LCE Engineering because there is not much aftermarket for the fourth and fifth generation toyota pickups.

Simply awesome
First of all, shipping was super fast! As for the exhaust itself, just by looking at it, you can feel the quality oozing from it. PRE INSTALL: I am not the most equipped guy in the world nor the most experienced, but I still managed to install it in my backyard in the snow, wet and miserable. Still felt great when I fired it up for the first time. POST INSTALL: The sound impressed me! I was almost anticipating a ricer sound, but instead I got a deep rumbling tone coming from my truck. Finally, shipping might be higher than if I order local, but it is totally worth it! You can be sure I'm going to buy from LCE again

Just what I needed
Quality, fit and finish were awesome, Installation was a breeze. Actually took longer to fix broken studs(previous owner) than it did to install the entire system.
