Best place for an exhaust would be MIJ in Walsall. They have doine them on two of my ST200's now and they are good systems. Will build it to sound the way you want it to sound.

As for chipping it unless you have done some serious mods then it wont need chipping justy for the exhaust.

If you need any further advice pop along to either:
