I recently invested in a custom exhaust modification. After researching and seeing the prices of the Miltek systems etc I was heart broken at how much they cost!, especially the variable opening ones!
Anyway back to the point I decided to just pay my very good local garage just £350 and they chopped my back boxes off and welded straight through titanium pipes with new tips and it sounds awesome!!
I thought I'd share this and if anyone's interested in cheaply making your car sound awesome then give me a shout or go to your local garage and ask them.
It hasn't affected my S5 in the slightest, no lights, no difference in performance nor fuel economy. It just sounds amazing.
Can I upload videos on here?
