I already have the Herrod Headers & High flow cats. I do not want to do the total cat back exhaust, but only replace the mufflers.

I think the pipe size is OK & want the best bang for the Buck.

What have you used & what results in both power & sound. :driver:

Thanks

Iv'e got the whole system, but mixed. Herrod headers and hiflo cats and the rest is D&T as it put out more power than the Herrod (dyno'd both) and it sounds real good. Also the D&T is twin all the way.

How many KW did you get from the cat back?

How are you enjoying the herrod headers and cats? Sound and performance change much.
