i asked powerlow if they could build a twin exhaust for my car. i want each exhaust sitting roughly under both rear lights but they said they mite not be able 2cos of the rear wishbone.does any1 know what there going on about
What they're saying is that the fitting of a custom made exhaust system is limited by the underbody components - suspension, fuel tank, etc.
Two tailpipes would just be for show - they're probably politely telling you that they know what they're doing & if you just want looks rather than performance, then go elsewhere.
I did tell you what's going to happen if you fit a loud exhaust though...
