On my first TR7 I fitted a Rimmer stainless exhaust. I vowed never ever again would I buy one of their exhausts. The fit of it was terrible the bends were wrong so I had to make it fit, speaking with them on the phone wasn't much help either. Wouldn't accept that it didn't fit correctly just kept saying we've sold loads and had no complaints.
Yes S&S might nor have an online catalogue like Rimmers, but just pick up the phone and speak with Steve he will advise on what would be best to suit your application. If you buy from him it will fit first time and a good chance be cheaper than Rimmer
