Hey guys I have a 435i and I'm really looking into a cat-back exhaust for around $1,000- $1,400 but I want the M4 design with the splitter and quad exhaust, I've seen the plastic clip that you can order that have the proper cut-outs for the new exhaust tip locations, cheapest one I've seen is around 187 before shipping, now I'm wondering if I might need to weld or do any chassis modifications to fit the new exhaust. I currently have a stage 1 MHD Tune. I also want to put style 666 rims on my car, I'm wondering if its wider than my 255/35 ZR19's and if they are wider, by how much and will it fit in my wheel well.

Many thanks!
