i am looking to buy a new exhaust system for my erst and was wondering wich is best for sound and performance and also the bore sizes as i no there are two differ sizes do they make a diffrence, and do both bore sizes fit on the turbo??

 

a good exhaust is scorpion 2.5 bore with 3 inch tail or a 4 inch

 

mongoose 2.5" bore for the erst,scorpion is pants,too restrictive

 

scorpion every time on a erst

 

as jambo rst says mate, steer well clear of scorpion as there has been many posts on here about them being restrictive due to the bore size exiting the silencer, mongoose or magnex all the way mate.

 

I had a Scorpion on mine, sounded great.

 

scorpians sound the bollox but at the end of the day its all about performance, mongoose all day
