I'm already pretty certain I'm going to do it already, but the exhaust tip for the exhaust I'm planning to buy will stick out of the rear bumper, unlike the stock exhaust which is angeled towards the ground and is hidden. Will it be a problem for me to cut out a slot for it to fit as intended...

Appreciate any replies and responses or advice btw... Basically have a pd130 suddenly stopped at a set of lights after running fine for 400 miles since owning. After 2 seconds or so just cuts out... It starts , then stalls.... Checked basically everything possible mechanically and seems fine...
