2018 4Runner July 10, 2019
Reviewer: Robert Hare from Glendale Heights , IL United States  
Have around 1000 miles on mine now. Sounds like marbles in a dryer now at low idle and apparently that is normal. Started off nice and smooth though.

Magnuson /2019 T4R May 30, 2019
Reviewer: Dmitriy Leytman from Chatsworth, CA United States  
The subject of this review is Magnuson S/C for my 2019 T4R. I am very pleased with this product. Having tried the URD Whipple first, I found out the hard way that it had inherent issues like noise and vibration, especially at low RPMs like less than 1k. Hower: When I switched to Magnuson, all those issues were resolved: Magnuson S/C was quiet, and had no vibration issues. In addition, gas mls is about the same with good driving skills. I have 33" tires, a snorkel, winch and C4 bumper. I get about 18mls on highway and 15 city. I love my set up with magnuson in it!!! Hands down Magi has invested a lot in R/D unlike other brands. Will  buy Magi again!
