Yea, when I was on their site, the complete exhaust was almost $2.5K. I was hoping most of the expense was in the carbon canisters, and the headers themselves wouldn't be too expensive. $1600 would be way too much.
In a previous post, I was talking about the crossover pipe on header sets. I remember seeing a set of Mark's exhaust on here as well as ebay and did notice that there was a crossover pipe in place of the box where the factory rear cylinders dumped into, (not sure if he gives you the choice to have the crossover pipe or if he just makes them that way). This is after both the front and rear pipes merge, so I guess this would do the same thing as having the crossover pipe for the front cylinders and box for the rear cylinders to dump into on the factory exhaust?
I have also found, at least from asking, that the full 4-2 HMF system does not have a crossover pipe. From listening to the two different exhaust on youtube, it sounds like the HMF exhaust retains more of the open end cap supertrapp slip-on sound, where as Mark's didn't seem to sound quite the same. Although I know my laptop speakers can't do either of them justice. Do you think the lack of the crossover pipe is what makes the HMF exhaust sound more similar to the Supertrapp slip-on sound? Is there a performance advantage to equalizing the exhaust pulses from the left and right sides of the motor?
I know mine is the over under, I just wasn't sure if they made different versions of the over under. Thanks for the info!
