Borla S-Type Catback Exhaust question
I have a 2013 Scion frs, and I ended up buying this exhaust from a guy for a really good deal. When I took it to get installed, the mechanic mentioned that the OEM donut gasket wasn't the right size for the connection. He said there's a chance it could develop an exhaust leak over time, if it isn't already leaking.
This might've been my fault since I bought an exhaust that doesn't technically fit my car. I had heard from other people that it does fit, though. Has anyone else run into this issue with this exhaust on an frs? If so, what size donut gasket did you end up using, or did you just stick with the OEM one?
I ended up installing it with the OEM gasket, and I'm not sure if it's related, but I think I'm getting a bit of drone. I've never experienced drone before, but after a long drive my ears feel kind of clogged, and I almost feel deaf afterward lol. It mostly happens around 3,000–4,000 RPM. From what I've heard, this exhaust isn't really supposed to drone, so I'm trying to figure out if it's because of the gasket or if that's just how the exhaust is supposed to sound. Overall, though, I think the exhaust sounds beautiful it is perfection!
Thank you everyone!!
