The CorkSport Advantage

Performance Benefits:

The CorkSport 3.5” Turbo Back Exhaust was developed to be the ultimate exhaust for your MS3. The 3.5” diameter piping and bellmouth design are large enough to efficiently support ~850+WHP. While you could make that power on a 3” exhaust, a 3.5” typically will make the same power on less boost or even make more power with minimal tuning changes. Even on lower horsepower cars, the CS 3.5” exhaust shows benefits to turbo spool time. On a car with built motor and supporting mods, we’ve seen spool time to 30psi improve by up to 300-500RPM compared to a typical 3” exhaust! This car also held boost better at higher RPM due to the added flow.

Great New Sound:

The added flow of the 3.5” CS exhaust also adds some volume to your MS3. By using high flowing straight through resonators, we were able to eliminate drone and unwanted sounds from the exhaust without impacting horsepower levels. We created a system that is surprisingly tame while cruising yet when you hit the throttle on an open road, the CS 3.5” exhaust is rowdy, with comparable volume levels to our existing non-resonated cat back exhaust. The extra-large pipe does offer a unique ultra deep tone that we haven’t heard on most other MS3 exhausts!

Fitment Inspired:

With the larger pipe, we wanted to not only provide great fitment but make it easier to deal with your downpipe. By separating the upper and lower sections of the downpipe, we were able to alleviate some of the difficulties when installing a DP on your MS3. The bellmouth can be easily accessed when attaching it to the turbocharger without the pipe section in the way. Plus, we ensured plenty of clearance for sockets and/or wrenches for tightening. You can even leave the bellmouth attached to the turbo in case you need to remove the downpipe or turbo for maintenance! The rest of the exhaust was designed for direct OEM fitment, despite the huge pipe size. The only modification needed is a slight bend to an underbody heatshield!

Materials & Manufacturing:

Starting at the turbocharger, the CS 3.5 inch TBE uses a cast 304 stainless steel bellmouth for strength and reliability. From there back, all piping uses CNC machined V-band flanges TIG welded to mandrel bent 304 stainless piping. CNC machining ensures a leak free seal, TIG welds ensure high strength, and mandrel bends ensure smooth exhaust flow. We control sound using straight through resonators with high quality packing materials. Finally, the exhaust is finished off with polished dual layer tips in 112mm (4.4”) diameter that included a laser engraved CorkSport logo. All combine to make an exhaust that looks, sounds, and performs great that will take all the abuse you can throw at it!

Hardware and Accessories:

Included with your CS 3.5” exhaust is everything needed for installation. This includes stainless v-band clamps, brand new downpipe mounting studs & lock nuts, and replacement polyurethane exhaust hangers. We include the CS poly hangers to ensure no vibrations or rattles with the tight fitment of the 3.5” exhaust. Finally, the thing we’re most proud of is our custom MLS downpipe gasket included with each kit. We port matched it to the DP bellmouth & CST6 to ensure no flow restrictions whatsoever!

ADVISORY

For off-road & race use only. This means keep it on the track and not on the highway.

A check engine light (CEL) will be illuminated on catless and some catted setups as a result of installation.

Note: This is a complete Turbo Back Exhaust System from turbo flange to exhaust tip. This is the only way to purchase a CorkSport 3.5” Exhaust System because we wanted a true 3.5” pipe from turbo to tip. You CANNOT purchase the Cat-Back Exhaust alone.

Strongly advise against combining this exhaust with a KO4 or CST4 IWG. Overboost/boost spiking may occur on some IWG and EWG setups. Refer to fitment tab for details.

If you have a CorkSport Turbo with external wastegate housing, the wastegate will need to be moved to the turbine housing directly and a new dump tube used. Check out the CS EWG Dump Tube for 3.5” Downpipe for more information.

NVH (noise, vibration and harshness) in the cabin of your vehicle will be increased by the installation of this exhaust.

Only fits on turbochargers with OEM downpipe flange shape.

If you have a CS exhaust manifold with EWG on the manifold, the EWG dump tube will fit with CS 3.5” downpipe.

Slight modification to rear underbody heatshield required for installation.
