Default De-cat headpipe or buy aftermarket

I'm not handy and would have to get a pro to remove my cats. Is it just as easy to go aftermarket and get the header or get the work done and remove what I've got. $$$ difference???2011 FLH w/ Jackpot slipsThanks again everybody!!

I'm not a believer in removing the cat. Fuelmoto makes a really nice 2:1:2 pipe.

My experience with intake and exhaust mods on these new bikes is that the Computer will have to be re-mapped or the bike will run like SH-T!

Do you have a friend that could remove the cat? If you were in my area, i'd do it for a bottle of Crown!!! If you're going to get an aftermarket headpipe, you're probably going to need to get it re-mapped anyways. I've read different posts, about whether removing the cat actually helps performance or not....so, who knows??? I think it helped(sure sounds better anyways)!

I really can't comment about any performance gain with what I did since it was done at the 1K service, but it is very much cooler than before. Here in south AL in the summer, getting rid of excess heat is important for rider comfort and what I believe to be engine health. Wish I knew how to weld and had the equipment, but I don't so went with the V&H set-up. Happy with it and the sound also

Keep the stock pipe you may need it.Buy FuelMoto headpipe install it then wrap it.Add slipons and no remapping needed.

From a tuning perspective you can get issues with crosstalk between the O2 sensor readings if you just gut the stock headpipe because of how it's designed (it turns into a big resonance chamber and the O2's no longer read correctly at certain speeds/loads). The computer will have a hard time reading erroneous info and chase it's tail, so to speak. Now, there will be a line of 50 people coming up to post here shortly that they gutted their cat and it runs fine, but they're most likely either running PCV's with the O2's disconnected, or they don't normally ride in the rpm range where the crosstalk occurs so they don't notice the bike being more sluggish than normal.

If you're going to remove the cat it's best to buy a headpipe like the Fullsac unit that doesn't have sensor crosstalk issues.
