Re: Anyone mod their 4 series? Please share view
Sorry, i got the price remembered wrongly. $3.8 is for the muffler. Downpipe is another cost.
For power gain or loss, i don't feel much of a difference.
The reason why i chose quad over dual is because in terms of looks, it feels like it gives me 40bhp more fierce looking! haha
5now5torm;1125665 said:$3.8K for eisenmann quad and DP is a pretty good price.
Any low end loss experienced? I chose the dual pipe over quad pipe because I was concerned about low end loss.
