only fill 98 RON and if you want more response from the engine use octane booster additive. get rid of K&N, you gain nothing from it, quite the opposite and you risk wearing out the engine prematurely because it lets small particles through.

service book seems to say every 90000KMS? also has anyone removed the last muffler box and replaced it with straight pipe? was it expensive and was there any gain in sound or performance
The exhaust pipe is carefully calculated and designed by German engineers to provide a system that is a compromise between noise and performance. The complete pipe and silencer system are designed to extract the gases out of the engine efficiently. Any unprofessional changes to the system will most likely end up in loss of power. Don't tinker with it unless you know what you are doing. I bigger pipe does not necessarily mean better performance.
The exhaust gases flow in a pressure wave form which varies according to engine revs. Ideally a high pressure wave travelling through the pipe at each exhaust stroke provides a low pressure wake to suck the next wave out. Too large exhaust pipe may cause a standing wave thus acting as a blockage, in low revs.

And all of that would be relivant, if it wasnt turbocharged.
Turbocharged bigger is better =) but only after the turbo, so dump pipe onwards.
Large exhaust = less resistance = more spool.

dunno im used to loud cars after 3 ss utes and wouldnt mind a bit off a growl from the sri i would use the same diameter pipe that opel used just delete the rear muffler.
