ISR Performance MBSE Dual Exhaust (Blue Tip) - 98-05 Lexus GS300

The ISR Performance MBSE dual exhaust with blue tips is a catback system for the 1998 to 2005 Lexus GS300 and the JDM Toyota Aristo. Built from mandrel bent stainless steel, it opens up the restrictive factory exhaust on the 2JZ-GE and gives the car a deep, aggressive tone with a pair of heat-colored burnt blue tips at the rear. It works on both naturally aspirated and turbocharged 2JZ engines.

Specifications

• Construction: precision TIG welded stainless steel with a brushed finish
• Piping: dual 2.5 inch diameter rear sections
• Tips: distinctive burnt blue finish
• Layout: single 3 inch mid-pipe feeding two rear muffler sections

Sound and flow

The dual muffler layout spreads the exhaust volume across two canisters, so the note stays deep without becoming harsh. Mandrel bends keep the pipe diameter constant through every curve, which matters on a turbocharged GS300 or Aristo where exhaust restriction directly limits boost response.
