ISR Performance GT Single Exhaust - Nissan Skyline R34 GTT Coupe

The ISR Performance GT Single exhaust for the Nissan Skyline R34 GT-T coupe is a 3 inch stainless catback that sheds weight compared to the factory system and gives the RB25DET a deep, aggressive voice. Mandrel-bent tubing maintains flow all the way to the 4.5 inch tip, which helps the turbo breathe and supports more power than the restrictive stock setup.

Build quality

• Mandrel-bent 3 inch stainless steel piping for corrosion resistance and flow
• Precision TIG welds throughout
• Brushed stainless finish with a polished muffler
• 4.5 inch tip
• Lighter than the factory exhaust

Fitment

Exclusively for the 2-door R34 Nissan Skyline 25GT-T coupe.

What's in the box

• 1x 3 inch mid pipe
• 1x 3 inch muffler section with 4.5 inch tip
• 2x 2-bolt 3 inch exhaust gaskets
• 4x Bolts and 4x nuts

Pair it with a downpipe

This catback bolts up behind the downpipe section. For a full 3 inch path from the turbo, match it with the ISR stainless 3 inch downpipe for the R34 GT-T so there is no bottleneck ahead of the catback. On an imported R34 the original exhaust is often the weakest-looking part of the car, so this system is as much a visual refresh as a performance one.
