I have removed the cats on my 88.5 TR replacing them with Capristo test pipes. So far so good. Now I am thinking about a Capristo muffler. I am collecting quotes.......Mike on a previous thread has a good US price. Has anyone ever heard/ done business with Supertweaks out of London? Maybe it is because of the Trump tariffs, but the London price is 2455 pounds. This includes 5 pounds for shipping. You guys do the math......is Supertweaks legit?
