ive had the same megan exhaust system and coilovers installed since 2006. I heard there is a difference in megan then and megan now, however i must say its a hit or miss, i mean every company has a batch of parts that was made on friday or monday. a good friend of mine has been throught 3 2871's. went to a no name brand 20g, 360 rwhp later, he hasnt looked back since. I think its alwasy gonna be luck of the draw. some times you win, and well some times you get
pwnd!
