Recently made the (superior) switch to the G from a unnamed German brand, and was hoping to get some help and opinions as I am a new G owner. Looked into some exhausts and it seems like topspeed pro 1 is on the cheaper side and the ark is possibly the best. I know there are threads out there about this, but I was hoping get a definitive yes as to the topspeed fitting the X and maybe a link. Also looking for any advice for a new G owner, and any mods suggested.

 

TopSpeed does fit the X, here's the thread, then the particular post w/ pics on an X

The exhaust they currently offer has cheaper, poorly finished tips than the one I have and the one you'll see in that link. If they offer the older rolled tip setup than I'd recommend it, the current straight tip version I would pass.
Another option for an affordable exhaust w/ a nice look would be the Tanabe axle back Medalion model. It won't have the deep exhaust note of the TopSpeed but a bit louder than stock and a very nice finish for about $650.
BTW, welcome to the site & enjoy your new G
