Austin Racing Slip on?

Thanks! I did send them 2 emails over the past week but no reply

I noticed that too, and wouldn't like it either. That's what happens when you just adapt a random can to a bike. That's why I went with Graves (no springs, no bands, and a proper bracket; looks OEM). That system needs more work IMO.

The only thing louder than our slip-on (and just a little bit), while retaining the cats, would be just a tip... but it'd sound raspy as hell. And look weird too. Ha ha. Even the stock exhaust is already straight-thru, so it can't get too much louder than that. What I liked about the Graves is the awesome deep sound, especially around 3-4K rpm. It's actually borderline loud to me already, so you must really like loud exhausts. Ha ha. Don't like to piss off neighbors, attract undue attention to myself, and having to wash my gear/clothes after every ride due to awful fuel smell. Oh, and the extra expense of a mid-pipe, and tuning the engine (you have to). Graves has several cat eliminating systems while keeping the EXUP, if you want to go that route. Good luck.

Well, lets try to get this thread back on topic again. The pipe comes with the can, an adapter tube, two springs, a clamp, and a db killer. Out of the box it already comes assembled, so installation takes a minute or so after removing the stock pipe. Obviously, this pipe does not have a bracket like a Graves or other slip-on designs. The only explanation as to why, is the assembly is fairly light, so the bracket just isn't needed. I will try to get a total weight for it later and edit this info in, but a rough guess is 1.5 to 1.75 lbs. I too was skeptical of this lack of a bracket, and of course the first thing I did after installation was grab at the can and attempt to move it. The most I was able to move it (with quite a bit of force) was about 1/2 millimeter to 1 millimeter measured at the end of the can. I removed the springs and looked at how the joint is assembled. The adapter pipe goes into the can 40mm deep, and the adapter tube butts up to the perforated tube and is held there with the springs. The pipe to can fit is quite tight, which is evident from the small amount of movement in this setup. The springs are not too difficult to install, and when assembled I could pull out the can maybe 1mm at the most, while twisting and pulling as hard as I could.





After riding I could notice no looseness or sagging of the pipe. I even grabbed it with a rag and tried to move it while hot, and got the same amount of play, less than 1mm. I will assume that if you removed the bracket bolt holding on a Graves pipe, you would probably get no movement, being that is a one piece pipe, so why Graves even chose to put a bracket on their pipe if it doesn't even move anyway is beyond me, but they probably didn't want to hear any complaints from customers about removing a perfectly good bracket even if it isn't needed anyway.

Alright, lets move on to the can. Total length is 9 inches, inlet diameter is 60mm, which continues all the way through the perforated section. This section is roughly 6 1/2" long. Packing appears to be the usual fiberglass.

I just did the cat delete pipe and ecu flash on my bike with the graves slip on but I still like the Austin racing look better. Especially the low mounted one but I don’t want it to be extra loud. I also peeled off the factory graves sticker that was red and orange and ordered this one from Graves instead. 

The Graves slip-on is the best looking, and best sounding IMO... BUT, with everything stock. It looks really weird with a midpipe, so I agree with your statement. Both are going to be stupid loud without the cats anyway, so I wouldn't worry about maybe 1dB louder with the shorter AR unit. And if AR offers a 'dB-killer' (do they?), it'd make even more sense, to quiet it down a little. Just make sure the fitment issue was (or can be) resolved.

By the way, that gray decal definitely looks better than the yellow one, but I still prefer the stealth (or OEM) look, without anything. Good luck with the swap .

PS. Hey, rotate the clamp, so it looks smooth (not showing the bolt). Look at my pic. Since you also removed the ugly seat strap, figured you'd like a clean look at the exhaust too. Ha ha.

Here ya go (I mentioned it twice):




Clamps rotated-check, seat strap gone-check, 12lbs lighter-check. At least with the butt plug, it sounds more like elp's ride.

Better stock up on socks
