Well I have been driving the car a lot in the last two years. I have most of the major stuff done. I've been tinkering with the little stuff now. I had the exhaust done earlier this year, the guy came in when the shop was closed to do the work so we wouldn't get interupted. I had originally asked for an H pipe but he ran out of time that day so I said I'd come back later. I've been scouring the web for Dyno or Drag ET data that shows the benefits of an H or an X over straight pipes. Of Course many forums have opinions that wildly vary as you might expect. The few links I have found to data are usually from a someone promoting there system so I don't know if they are biased. In many of the cases where I found head to head comparisons the X and H had so close of results you could say there was really no difference. I haven't found where any testing was done comparing and X or H to straight pipes. I know the theory of scavenging but if it's worth 2 HP is it worth the expense? I don't drag race and have never had the car on a chassis dyno so I have to go by seat of the pants feel. Cost varies from $40 for a Jegs universal H kit to close to $200 for Dr Gas X pipes. The there is labor to weld it in. So anybody have real world experience?
