Does only changing the Y pipe makes a difference? I do understand that changing the whole exhaust system is going to make a lot more. I live in Sweden and during the last couple of years a lot of complains have been made due to the increase in sound level (for most part) an aftermarket exhaust makes. so I want the look and sound as close to stock as possible

Feel free to post your thoughts, pros and cons on different Y pipe brands and so on
Yes, the stock manifold is 48mm i.d. and the stock outlet on the cylinder is 50mm.
I don't know what other companies results are or aren't, but we picked up a pile of power in the mid range 8-9, and a solid 4-5 lb/ft of torque. And 5 more peak hp. We recommend adding more weight to the clutch with our Y pipe to harness the extra power.
