Switching exhaust tips:
1) Find a recommended muffler shop or exhaust specialist (check with local gearheads)
2) Bring tips or buy from the installer, and the tips should be made from Stainless Steel with 2" diameter
3) Installer cuts off old tips.
4) Installer flares the stock 4C pipes (which are 1.9", a weird dimension) to mate well with the aftermarket tips.
5) Hopefully, they have a drive-on lift, which does not require lift supports to be placed under the car.
Things to know: Stainless steel tips mean you have matching metals -- something you must do. Choosing non-stainless tips ensures that corrosion from dissimilar metals will eat your entire 4C exhaust system in a year, leaving you with new tips and a pile of rust.
"Carbon" or carbon fiber tips are acceptable, because they are non-metallic and will play nice with the pipework left behind from the old exhaust. Generally, the look of carbon fiber is good, but usually at 4-5 times the price of stainless steel. If the mating surface of carbon fiber tips is not carbon fiber, it is extremely likely they are a carbon fiber and stainless combo, which is perfect.
Small projects are exceedingly annoying because they share so many steps and warnings with big projects. Like painting one wall of a house. Still a lot of steps and considerations!
