ISR Performance Stainless Steel 3" Downpipe w/Flex - Hyundai Genesis Coupe 10+

The ISR Performance Stainless Steel Downpipe is a 3 inch all-stainless downpipe with a flex section for the 2010 and newer Hyundai Genesis Coupe 2.0T. Bolts directly to the factory catalytic converter or an aftermarket test pipe, opening up exhaust flow on the Theta 2.0T turbo for meaningful gains on any boosted Genesis build.

What It Does

The factory Genesis Coupe 2.0T downpipe is restrictive and includes a catalytic converter section that chokes flow above the factory turbo's stock output. Replacing it with a free-flowing 3 inch downpipe is one of the highest-impact bolt-ons on the platform, particularly when paired with a tune that can take advantage of the reduced back pressure.

The flex section between the turbo flange and the rest of the downpipe absorbs engine movement and thermal expansion, which is a real concern on the 2.0T platform because of how much the engine torques on its mounts under boost.

Pairs Well With Other Mods

This downpipe is at its best when combined with:

• Aftermarket test pipe or high-flow cat (downstream)
• Aftermarket catback exhaust
• Tune that takes advantage of the increased flow

Running this downpipe alone on a stock tune will produce some gains, but the full potential comes out with supporting mods.

Fitment

• 2010+ Hyundai Genesis Coupe 2.0T (BK1 and BK2, Theta 2.0T engine)

Not for the 3.8 V6 Genesis Coupe (different exhaust routing entirely).
