EXHAUST TEMP INCREASE WITH CAT DELETE??

[pugpower]

A question for you more experienced/technical Captains:

I recently put Corbin hard bags on my R3 with stock exhaust. I've heard some captains say they melted their bags or had some heat damage issues. I have extra heat tape on the bottom of mine (I've only ridden it home from the dealer since the bag install,been witches tit cold until today) My dealer (is a good dealer) has told me they have sold several sets or Corbins on Rockets and their customers have had no heat problems. I am going to do the CAT bypass (delete) and the new tune to dress it up. Is the CAT bypass going to make the exhaust hotter, or should I say hot enough to make a problem where there would normally not be one??

Thanks,

PUG

Removing the CAT will reduce exhaust temps.

Just thought of something, if your bike is a 2005 you may not have a true catalytic converter. Some early Rockets have a CAT box but there is no catalyst inside. I think it has an "N" stamped in it if it is just a box lacking the catalyst. In this case your exhaust temps are already lower than a true CAT-equipped bike. A cat delete eliminates the restrictions of the box and further drops exhaust temps.

Going to my dealer once I put the bypass on and getting a new tune. All I'm really after is a better sound (stock exhaust w/o CAT) and having her run right after the bypass (new tune). Heard many Captains say that Cat bypass w/stock is nice sound. Not after rattling my teeth, just a little rumble. At this point **** thing is so quiet you have to wonder if it's running!

well I guess I should add, once I get a CAT bypass. I'm on the hook for Warp9.9 CAT bypass once Sam has his Pred pipes done.

Thanks again for the info!

If you put the cat bypass on without the correct tune, the bike will run leaner, which will make the exhaust hotter.

I run TORs / cat by pass with a PC-III and also have Corbin bags and I have no problem, other than exhaust residue builds up on the bottoms, but it comes off with wax..

Yes, what he said. My previous post assumes a corrected tune.

How much clearance do you have between your bags and the upper pipe? If you have less than 1/2" you are going to have a problem. Don't wait until you do. Remove the upper pipe and loosen the lower pipe and gently rotate it out of your way, drill out your upper muffler bracket with a 1/2" drill bit and when reinstalling just hold the upper pipe down as far as it goes and tighten down the muffler bracket bolts, that should give you enough clearance. I also put a little extra Cool Tape on the bag just above the pipe right behind and next to the Corbin applied insulation and mine's fine now.
