I really want a Eisenmann quad exhaust system. Really. After looking into adding an after-market exhaust that wasn't Dinan, to my Dinan modified 335i, I decided to wait until I'm out of warranty before I change the whole exhaust system on my car. A good modification that is low cost and adds a nice after-market look is exhaust tips.I went with 3.8" chrome tips from Cyba off the E90 board. Ordering was easy and the price was far
better than Dimsa tips. The Cyba tips ran $99 including shipping. Dimsa tips are $145 (special right now down from $175) not including shipping. Locally, I went to S & K Muffler in Royal Oak, Michigan to have the tips installed. They do require that the stock exhaust is cut and the tips are welded on. Cost was $60 for the installation. It took about an hour to install, while I waited.
