hi,
i have done two conversions for people. the first one i used a leather gaitor surround that came off a volvo. fastened it under the centre console with the metal plate you use to fasten the p6 rubber gaitor with. so really any car that just has a leather gaitor will do the job. if your car was an auto with the 5 speed conversion, there is no need for any alteration with the exhaust, you use the auto exhaust that was already on the car. if you have converted a manual car to a 5 speed conversion you cannot use the auto down pipe as the transmission tunnel is in the way. you have to use the manual down pipe, which i saw on a particular car had been extended by a couple of inches just down from the manifold, why i am not sure as both conversions i did were on the autos. so before doing any thing silly with a new down pipe, try it first then alter if necessary. any body want any more help or info ring me on 01302 750747
