I currently have a Prodrive PPP backbox on my MY00, after hearing some of the exhausts on Sunday at the karting i want a bit more of a growl for mine at the lower revs.

What would be the best way to go about this? Center section, Downpipe or both?

I am reluctant to do both at the moment as I am gettting the car RR'd on the 8th and I would like to see the difference that each of the modifications makes.

 

Downpipe. Then change the backbox to a less restrictive one if you can live with the noise - I cannot so have kept the PPP one.

 

I like the design and the sound of the PPP one so I really dont want to change it.

Any other comments?

 

I agree with John, go for a downpipe which will make your car sound deeper and growlier as well as making the turbo more audible. Then go for a BB and possibly a centre decat.

Ian,

I was going to go for a SS DP and see what the noise was like. After than (if it wasn't too loud), I was going to go for a Magnex (with res).

I can't live with the full SS drone so I was hoping the combo of PPP BB + Magnex Res centre would keep it down to acceptable levels....

Shouldn't you be decorating anyway!
