Aftermarket exhaust

[kozzmozmo]

I have been eying up a full yoshimura exhaust on ebay for dirt cheap for my 2002 gsxr 750. I was wondering what other mods would I have to do if I installed a full exhaust? Would I need a power commander or a tune up?

At least a high flow filter (BMC, K&N) It may make it a little twitchy at low RPMs. If you don't like it you can look into a PC.

if you are going w/a full exhaust I would also get a pc to go w/it, you won't regret it.

With a full exhaust (not a slip-on), you are likely going to make the bike too lean which will cause long term damage to the engine. To correct this you will need a PCIII like system to remap the fuel system.
