Having moved to a new house with a steep drive I had no alternative other than fit a side exit exhaust as the catalyst inners were being destroyed.
That worked for the exhaust but approaching from one uphill direction with a passenger the bumper support bracket one side will scrape, have do a three point turn to get in unscathed.
Mine is a 93 +4, no idea about the clearance on other models and off course angle of drive and approach will vary. Some ferry ramps are also a problem and they can vary with the tide height. On a drive you could try using coloured chalk to see where underside is scraping or even putting a couple of extra pounds in rear tyres, or getting the wife to get out first, thats the dangerous bit.
