hey i was looking at carlsson's website and noticed their dual left and right exhaust system. will this fit on my C320 without any modifications? how about the oval left and right exhaust system from lorinser? thanks if anyone has any web sites to where i can purchase these systems it would be great. carlsson body kits and exhaust systems. i know performanceproducts.com has the lorinser exhaust but i want to see how much the carlsson one is. thanks a lot!
