IMO - No exhaust will ever sound exactly the same as another...too many variables such as pipe length, bends, etc. You can come close, but it's really hard to listen to an exhaust then duplicate it and get better than an approximation.
Your best bet is to customise it until you like it, based on a setup you like the sound of. Moving the muffler along the pipe will produce gradually varying tones.
So I'm not going to tell you what's the best system - that varies with personal opinion anyway

Just find one you like and then chase down the owner or crawl under the car

Then copy it and play with it.
