it will only smooth the sound at tickover dave they can indeed help in a small way with output as the revs clime but not in all cases there have historicly been just as many split systems as the have been x or cross pipe deisgns

what is garanteed in all cases is smoother refined sound

but that is not always the end aim  and i like my v8s a bit raw

I have the Hedman headers on my 360 and they are inside the frame.A doddle to fit and remove, having just had to do it to change the flexplate.These then join into one behind the transfer case,and pass above the rear axle.It all sits above the skidplates.

joined mine at side of trans ....ran drivers side pipe in front of gear box crossmember then ran to rear in 3" pipe used 2.5" pipe for front and altered a grand espace back box as was a through type (2" in 2" out) by putting a 3" pipe through middle and re welding.. it works a treat and cost me around £68 in bits.....

makes no real difference to me as i'm with an I6. TBH a nice heavy v8 idle is always better than a smooth one. irrespective of exhaust design and routing

Are you any clearer about what you are going to do with the exhaust bulldog because reading this thread im very confused and glad i only have 4 and 6 cylinders to worry about. :greggmo:
The scrambler will probably end up with a cherry bomb on it, if only for ease of fitment with them being so compact.
