I'm pretty sure it's a 2nd generation of the car name 'Will' but i just couldnt find any info on the web. Remember the odd looking car 'Will' first produced that the rear glass bends inward towards the passenger instead of the normal looking car on the road?
Ok,found this article about how to make twin muffler/exhaust system that is consist of s-flow and straight flow at the same time.
but the problem is i dont know where to find the parts and if i can use another part...
