You were right. Rode a couple hundred miles today. Those cones sound killer. They are loud but not too loud.super happy with them. Great value for the money!

I promise I did my best to collect all the right information but I cannot get a clear idea about a thing.
Do I need to get a PCV and remap the bike after installing an xpipe? Or a simple 12min idle ecu relearn will do be job?
Consider I have a Thruxton R with an exhaust which is not original and a BMC air filter.

Thanks

Short answer is no, you do not need a remap as although it does indeed lean the bike out a bit it appears to still be in the safe zone. That being said, if you do a remap/PC5 will it run better? Absolutely. In my experience with all of my previous bikes, it will smooth out the bike and have better drive ability overall. Hard to explain but you can tell it's running richer.

I have the V&H pipes without baffles and will be putting in an x pipe in the next 2 weeks (air box snorkel removed). I am goin g to try the "Booster Plug which basically intercepts the IAT signal and fools it into thinking its a bit cooler out and thus the ECU adds a bit of fuel. Not a performance device (like a PC5) by any means but if it smooths things up I am good with it.

Sure thing! Be aware that there are a lot of members (or so it seems!) here driving their bikes around with xpipe, exhaust, etc. and as far as I can see, everyone is very happy with how their bike runs and performs!

Awesome work! that answered a lot of my questions.
I´m riding a Thruxton r with X-Pipe and V&H EU (with baffle), i noticed that when the bike is warm (most of all deceleratig from 4000 to 1500 rpm) there´s really a lot of decel popping. Really a lot.
I assume that is normal, right? It doesn´t mean the I´m running lean?
Thanks!

Bike with a few things added, such as... me. I prefer riding my bike to bragging about the chromed rear foot-pegs. Does that make me strange?

Is it necessary to keep the "heat shield" (the plate that holds the cat) when installing straight through pipes? (they have a balance pipe that goes through where the cat was)
