Hi, every time when I detailing my S5, I found it is pain in the ass to clean the exhaust tips! But the after market exhaust tips(CYBA) that on my 335i are so easy to clean (the attached image)! just hose off the dirt that's it! So is there any options for exhaust tips? Or I should replace the whole exhaust? I never replace exhaust on any of my cars since I don't enjoy loud exhaust at all but if there is an after market exhaust that doesn't sound loud then I may consider it too.
