Specs & Features

• The 2.5 inch primary runners from each catalytic converter merge into a single 3 inch outlet at the velocity merge, stepping up pipe diameter to improve exhaust flow.
• Bellowed flex sections on each primary runner absorb engine movement and vibration, protecting the welds and the catalytic converter flanges from stress.
• The dimpled gusset plate ties the two primary runners together before the merge for structural rigidity.
• Bolts directly to the existing 2-bolt catalytic converter flanges.
• Does not alter, replace, or modify any emissions equipment.
• This product is not CARB compliant and is not legal for sale or street use in California or other CARB-regulated states.
• ISR designates this product for off-road and competition use only.

Pairs well with:

• ISR GT Single Muffler Catback Exhaust Nissan 350Z (2003-2008) The ISR catback is the natural downstream companion for this Y-pipe. Pairing the ISR Y-pipe with the ISR GT catback creates a complete matched ISR exhaust system from the catalytic converter outlets to the muffler tip for consistent flow and tone from front to rear.
• Invidia N1 Catback Exhaust Nissan 350Z (2003-2008) Polished Tips For buyers who prefer the Invidia N1 catback, the ISR Y-pipe feeds directly into the 3 inch inlet of the N1 system for a complete exhaust upgrade on the VQ35DE.

OEM Part Numbers

• The factory Y-pipe and resonator assembly for the Nissan 350Z and G35 VQ35DE uses Nissan part number 20020-CD000 (confirmed from Nissan OEM parts sources for the Z33 platform). Customers can verify using the Nissan or Infiniti parts catalog with their VIN or chassis number, as part numbers may vary between 350Z, G35 Coupe, and G35 Sedan applications.

The ISR Performance 350z / G35 Y-pipe utilizes 2.5" stainless steel piping along with bellowed flex sections running from the 2 bolt catalytic converter flanges back to the high performance velocity merge. The Y pipe then steps to 3" stainless piping coming out of the velocity merge to the rear 3" exhaust flange. The Y pipe also features an integrated dimpled gusset plate tying the two individual runners together for increased strength and rigidity.

The ISR Performance Y pipe was designed to provide the best possible exhaust tone, ground clearance, and performance, all at an affordable price!

This will not fit on X model AWD G35s.
