I have a 09 with a two brothers on it. I've had the exhaust for around 10-15k miles maybe more. My question is when should I repack it or do I need to? What signs should I look for to know if I have to repack it? Thanks for the help.

 

If youve got the carbon fiber one you can start to look for discoloration of the carbon fiber which means its been getting too hot probably due to needing to be repacked. If yours is stainless you can listen to the sound and see if its starting to sound higher pitched and more hollow/metallic when youre in the mid-high rpm range. At 10-15k miles id definitely say you need to. I think around 10k miles is when most companies recommend it. You can always take it off and take it apart and have a look inside to check but if you dont need to do it already youre going to need to do it soon so i say just get it done now.

 

I just ordered a Yoshimura repack kit for mine. They recommend you repack after 10k miles. Mine is like 5k over due. It's going to be my first repack, I'll let you know how it goes. :P
