Good news. Kelleners is making new exhaust for the Mini. Mine will be one of the first 5 or so Minis to get it! It is being installed at my tuners shop now. I will let you know in a week how I like it. My tuner dumped my SS exhaust for the new Kelleners exhaust since I have the stage III/IV Kelleners kit installed. Expected WHP is 240+. We are now tuning the Mini. More to follow.......

BTW...Like JCW...Kelleners also issues stage build certificates and SNs for the stage III/IV builds. Look out JCW...Kelleners delivers MORE bang for the $$$$. And also Kelleners is partnered with Schrick on the stage kits.
