Thats quite a statement as I'm sure there are plenty of guys who know what they are doing running them.
Yes the tried and true 1"5/8 merged headers plus mandrel bend into a 3" Magna flow muffler is the one that has historically been the 'utimate' system, but people are running their street cars lower in the rear these days.
I ran that exact system on the street with the muffler laid flat next to the 1/2 head so I could get to the valves, but the flange and exhaust tip were constantly dragging on everything.
A mate just pulled his 1 5/8 merged system off his bus due to the same issue.
1 5/8 sidewinders appear to produce the same power but with increased clearance I personally feel they are a better style of system.
Firstly, as Matt said you need to determine what pipe size you need based off your valve size and cam etc, but A1 seem to be the best.
Rod Penrose stocks the better quality A1 ones but you need to get the muffler made up yourself, just make sure whatever system you get the muffler is located so you can get to the valves withoput having to pull the muffler off.
I'm not 100% sure if they work with the Berg rear traction bars.
I'm personally aiming to get something like the attached made up for my bug.
