Just having a look round some sites for stuff to give my astra a bit more bhp, as its having a rolling road on the 24th April.

Ive (hopefully) brought a precat decat pipe off a guy off here.

Would these make any difference at all:

If anyone has any ideas what would make it better for not a huge amount of money, could ya let me know?

Cheers!

Oh by the way its a 2006 Astra H SRi 2.0 Turbo 16v if that helps!
