X-pect air filter upgrade, exhaust?

[Redleader]

I’ve been looking through the forums but to no avail. Has anyone upgraded the xpect air filter with a washable or free flowing one like K&N style? I’d take mine out and measure but I’m away for the time being.

I saw that slip on exhausts don’t really do much other thank make noise which i like that mine is relatively quiet but I swear it’s so quiet people almost hit me. The slip on look like if you cut the old exhaust off you can weld or clamp it on there. Any experience?
