Pro Flow Exhaust System

All of our Pro Flow Exhaust Systems are made with 409 stainless steel tubing, 426 stainless steel straight-through Magnaflow muffler and 3/8" thick mild steel flanges. The straight-through design of the Magnaflow muffler offers the highest flow while still maintaining a smooth, yet authoritative tone without attracting unwanted attention. 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. This system will fit both 22R/RE and 3VZ V6 trucks when a 17.5" catalytic converter is used. We have the correct length converters available as well.

NOTE: Designed to be used with a 17" catalytic converter. LC Engineering does NOT recommend wrapping our exhaust with any sort of exhaust wrap. Doing so will increase the likelihood of a premature failure of the exhaust, as it holds contaminants to the exhaust tubing and increases the chances of corrosion. Exhaust wraps will void any and all warranty claims.

This product should not be used in a manner that violates Federal EPA Laws.

5 of 5 Awesome product!! April 25, 2022
Reviewer: BR from Rogue River, OR United States  
Literally the only 2nd gen bolt on exhaust system available, and it is exactly what my Runner needed - well worth the price, and it showed up quicker than I was expecting. Will happily deal with LCEngineering again once my 3.4 swap is finished!

5 of 5 Perfection! December 30, 2020
Reviewer: Nathan MCDONOUGH from Missoula, MT United States  
Replaced the old rusted out exhaust system on my 1991 4runner. I called LCE and made sure to get the correct system including a new Magnaflow direct fit catalytic converter. The hardest part was getting the old system off... install on this new kit is a breeze. Sound is great deep and throaty especially in first and second gear then it quiets down nicely for 45mph+ I highly recommend this system worth every penny.

We like the low growl at idle it has now Changed the cat as well while I was in there and now the BURO is humming and breathing so swell....system is installed on the truck 3 days after placing the order so shipping was quick as well.

5 of 5 Straightforward Installation November 19, 2019
Reviewer: Curtis Durham from Littleton, CO United States  
Received the cat-back exhaust for my 4Runner and had it installed the same afternoon. Removing the rusted flange nuts off the existing stock exhaust was the most time consuming part.
Looks and sounds great!
