I have a 360 in my '74 Javelin and am considering switching to shorty headers. When I was a teenager, I had full headers (Hedmann) but they hung down so low that they would scrub on speed bumps. So, I don't really want to consider the full headers, but the shorty would be an option. Does any one have experience with this. The rest of my exhaust system needs replacing, so I'd be interested in opinions about which supplier to get the pipes and mufflers. I'd really like to use the 3" if possible.
