PERRIN 02-14 Subaru WRX / 04-21 STI Exhaust Stud Kit w/Nuts M10x1.25 37mm (3pc Kit)

These Perrin exhaust studs are made from stainless steel, which helps prevent them from rusting or seizing up in your exhaust manifold or downpipe. They're designed to replace the factory bolts that hold your exhaust components together, offering a more secure and reliable connection. The M10x1.25 thread size and 37mm length are specific to certain Subaru models, ensuring a proper fit for the intended application.

Using studs instead of bolts can make future exhaust work a bit easier. Once the studs are in place, you can often remove and reinstall exhaust sections without having to deal with seized or broken bolts. This kit includes the necessary nuts to get the job done, making it a straightforward replacement for worn or damaged hardware.
