Weclome...Great pic...It really presents your car well...nice

 

welcome! love the wrap color.

 

Do the 200 cats make a big difference? Are they very noisy?

 

The 200 cell cats make the car sound great, best cost/fun mod I've done.
Obviously I've fuse 22 pulled also (well the equivalent with a remote switch) to get the full low down noise.

Measured the noise (3/4 max rpm 0.5 metre and 45 degrees away-as per uk trackday testing)
@5250 =113 db (just after the exhaust valves open if fuse 22 was installed)
