just purchased some di filipo headers 4 into 1's for an 08 xr8 fg sedan, unfortunately my budget is restricting me from buying their whole system which ive heard sounds great, was chasing some advice on a decent catback system to complement the di filipo's, i was thinking venom cats for a start i had them on a previous vehicle was very happy with them, any advice would be great cheers

I used an X-force 2 1/2" system and cats on my pursuit. It's not bad, not too loud,not too quiet although now that it's burned in it doesn't sound as good as it first did but it still sounds better than some others out there which, I have to say, sound bloody terrible! It hung a little low so I had to shorten the hangers but otherwise it's pretty good for a low cost system. Makes around 380hp with the usual bolt ons and it's a four speed.
I've got a blower to go on next so I'll probably change to a twin 3" from diflippo at some stage.
