Thanks guys. The extensions really didn't do anything for the looks, kinda like the after thought that they are, and I had so much work into building those pipes I really didn't want to start over.
We'll see on Sat, gonna do about 30-40 miles each way. Probably more than I've ever drove it at one time. I have drove it around town for a couple hours quite a few times but with frequent stops. It's never given me any trouble other than a fouled plug, or actually a carbon whisker shorted one out once.
The circle expands.
