Please note Quad Tips are available with optional Carbon RR Racing Tips!
(see photo of our new tips in the image library for this product)

This is our signature full cat-back exhaust system for Lexus ISF. Dual Magnaflow wide open mufflers with quad 3.5” exhaust tips, slightly louder and deeper than standard Borla. This upgrade option retains the large Borla resonator and replaces Borla mufflers with dual Magnaflow mufflers and quad tips. Borla is a great exhaust, but with this upgrade your back will look much better with the large aggressive oval quad tips and will sound better too! We feel that Magnaflow offers great mufflers at an affordable price -- we tested these mufflers off and on the track for over six months.

We developed our own system, which is an improved Borla (used to be the most popular exhaust for Lexus ISF). It is constructed from 2.5" stainless steel tubing, with X-pipe, and two round resonators instead of one flat Borla to improve flow and sound. This exhaust is made in the USA, and fitment is second to none. We have seen a 25-35hp gain with our full exhaust.

These tips may touch and burn the bumper a little. You may cover the edges around the tips with a temperature resistant tape. However, if you are very concerned about burning the bumper paint even a little, the only solution is to use OEM tips.

Please note that the Quad Tip Upgrade options are more tucked in than shown in this video.
