Didn’t get to use these and missed the return window but seem very well made

Hello,

Thanks for sharing! Sorry you didn’t get to use the Mishimoto adapter, but glad to hear it seemed well made. They’re known for solid build quality.

Regards,

Used on my 09 WRX

Wanted to switch back to stage 1. Didn't want to handle the headache of smog here in Cali. These were exactly what I needed for my stock downpipe to my aftermarket midpipe. Everything bolts right up!

Jason,

Great choice! The Mishimoto OEM Downpipe to 3' Cat Back Adapter is a great way to get your exhaust fitting properly with no leaks! Thank you for your 5 Star Review!

Regards,

Looking for a gasket

Purchasing the 3" adaptor and gasket was my means to replace my Mishimoto turbo back 3" exhaust gasket( downpipe to Y pipe ). Direct fit, couldn't find the gasket by itself the adaptor sits idle until it will be needed. Great product!!

Jose,

We appreciate your 5-Star Review of the Mishimoto OEM Downpipe to 3' Cat Back Adapter! I am sorry you couldn't find the gasket you were looking for! Please give Subimods Customer Support as we do have them available. Although, it is never a bad idea to have these exhaust adapters on hand! I am glad the gasket was what you were looking for!

Regards,

Oem downpipe to invidia n1

Great fit but if your downpipe was as rusty and mangled as mine you will have some exhaust leaks. Tried using some muffler sealer to try and fix the gap and it helped a little. But other than that it was a perfect fit.

Martin,

Thank you for your 5 Star Review! The Mishimoto OEM Downpipe to 3' Cat Back Adapter is one of the best options when installing and aftermarket cat back exhaust! Making sure all the rust is removed as well as the remanence of the old donut gasket is extremely important to make a perfect seal on the downpipe side and a new donut gasket is highly recommended.

Regards,

Adapter

Perfect fit with no alignment issues or sealing problems. Would highly recommend.

Kurt,

The Mishimoto OEM Downpipe to 3' Cat Back Adapter allows you to install any catback exhaust to your stock downpipe! It allows you to keep the donut gasket which provides the perfect seal. Plus you can install and awesome sounding exhaust with no leaks! Thank you for your 5 Star Review!
