@jonne123 So what’s your predicament here? Is a DEP system not sold in Finland, or are they difficult to import?
Can you buy some thing from Germany?
There are no good cheap exhausts, the cheap ones like Big One, Gianelli, Arrow, Athena are Designed for Mid-range torque and don’t offer the over-rev advantage the DEP is geared towards.
I’ve heard good things about the Athena exhaust, might be one to try.
There’s also Firebox and Spes pipes, which I believe you can still find also.

They aren't that expensive.

I am sure it would only cost £20 to ship overseas.

@jonne123 Buy the old model giannelli from Mopo Sport. It has a shorter and straighter "header" (alkukäyrä) than the new "regular" giannelli so it's more suitable for higher revs. It's alot cheaper than the dep but acts pretty similiar, my whole setup is pretty high end and designed to rev high but I have the old giannelli and mine revs up to bit over 13krpm, with the peak power being at around 10-11k.
