Exhasut System Advice..

Courtesy of Akey, cheers bud..

OK here is the general advice, this is a summary of a review and test a mag did some time ago:

1. If you fit a PCIII (or with a gsx-r get the bike put on a yoshi box) and get it set up you will get better response and more power with no external mods at all (bikes are set up to pass noise and emmisions from factory not best performance).

2. You can fit an end can without any modifications to the bike and it will do no harm what so ever (you will see more of the advantages posted in para 1 if you also get it set up with PCIII or yoshi-box).

3. If you fit a full system (down pipes, link pipes and end can) then you will probably need to get a custom map done (PC III or yoshi-box)

4. If you fit a full system and free flowing air filter you will definatly need a custom map on a PCIII (yoshi-box may also do but not sure)

what is a yoshi-box - the ECU on the GSX-R (may be other bikes but I dont know) is adjustable with a system called a yoshi-box (most suzuki dealers should have on, so if they have a dyno as well they can set up the bike). However the standard ECU only allows course adjustment of the map, which is why many people go straight to the PCIII and custom map, as the PCIII has finer adjustment.

Hope this helps.
