Re: Thanks for the link Gale, how did the Eberspae (archive)

The Eberspaecher fit & finish is very nice, almost indistinguishable from the OEM Boysen. Yes, a mig welder will go full around between the two pipes, just use a little more stickout. Jig it carefully to assure a good fit. I did a write-up in the URL below. By the way, Zigmont$ (deliberate typo to get past the censors) made me a deal of $370 delivered for both.

fit up? Did you jig and weld or did you use those clamps? My old system is still the one piece and I was thinking about using it for a template and welding the new one in place. Will the head of a mig fit between the dual pipes to be able to put a decent bead on it??

I put on a new Eberspaecher front resonator & rear muffler about 6 weeks ago. At first it was almost too quiet but after a 2k mile road trip, it has opened up a bit & has a nice low rumble at idle & still quiet when accelerating & at cruise. I've read oem is well tuned for performance unless you're making other mods to the engine as well. I included a URL below for AGP's comments on various exhaust choices.

Racing Dynamics deal that Bruno has going or the stock Eberspaecher. With R&D, the sound factor may be the deciding vote. Pricing would be about the same. Would rather stay with the quietness of the stock exhaust. Although I could be swayed to lean toward the Racing Dynamics if the sound wasn't loud and reverbs were minimized. Has anyone experienced the sound of either system? Need some feedback, thanks for your help!
