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.

Pro flow exhaust
Sounds amazing and fits perfect

LCE header and exhaust
Super fast shipping, great quality. I had a horrible exhaust leak in the stock manifold and bought this as a repair/upgrade. It now has a cool little exhaust note and I feel like it picked up some performance. This is the only performance enhancing mod I have done so far so I’m sure with additional upgrades this will only help with those future upgrades. The support from LCE was on point and I couldn’t be more satisfied.

Great Product
Highly recommend this exhaust system for your ‘85-‘95 Toyota pickup. Fit is excellent and it looks great as well. Am planning on adding the LC header as well to complete for exhaust.

Pro Flow 86 22re
After over a year of thinking back and forth about purchasing this exhaust, I finally did it. There were a few videos online that didn’t do justice. I wanted something louder than my old stock exhaust but not loud in the cabin. Read a handful of reviews of it being too loud or not loud at all. So I said F it just buy it and be happy with a better flow for your slow 22re. It’s got a low deep rumble tone that makes your 22re sound faster than it really is. I do feel a difference in highway driving, just feels smoother and some needed power. And that’s just with the stock cat and headers. Cabin noise is VERY minimal, like I’ve mentioned it’s a lower deep tone and without the annoying droning at all. Very silent at hwy speed. Truly blessed to have LCE around for great products my truck.
