ISR Performance Exhaust Y-Pipe - Infiniti Q50/Q60 3.0T

The ISR Performance Y-pipe for the Infiniti Q50 and Q60 3.0T replaces the factory section between the catalytic converters and the rear exhaust with mandrel-formed stainless steel and a proper velocity merge. On the twin-turbo VR30DDTT, the factory Y-pipe is one of the easiest restrictions to remove, and this piece opens it up while keeping ground clearance and a clean exhaust tone.

How it is built

• 2.75 inch stainless steel runners from each 2 bolt catalytic converter flange
• Bellowed flex sections in each runner to absorb engine movement and protect the welds
• High performance velocity merge collector
• Steps up to 3 inch stainless piping after the merge, ending at a 3 inch rear exhaust flange
• Integrated dimpled gusset plate tying the two runners together for rigidity

Why the merge matters

A smooth merge collector lets each bank's pulses scavenge the other instead of colliding at a sharp junction. The result is better flow through the mid-section and a deeper, more refined note from the 3.0T without drone or rasp. The gusset plate stops the two runners from flexing independently, which is what cracks lesser Y-pipes over time.
