I'm trying to make a mod car backfire. Usually it isn't a big problem because I just need to change the exhaust to a better one then the stock. The Problem is that there are no optimized exhausts for this modded car. Just the default one is modded, all others are just bugging around.
Anyone has an idea how to replace the better exhaust with the model from the stock exhaust? Or is there a similar way to make it work?
