Default Macs to Kooks...New dyno #'s

I had Mac mid-lengths with Mac cats, switched to Kooks 1 3/4 Stainless headers and Magna-Flo cats.

The macs and tuning I made 351hp

The Kooks and tuning I made 367hp. They made more power the entire range.

Excellent, high quality headers. They actually tuck up lower than my Mac y-pipe did.

Macs but no tuning yet, I can't find my sheet with the tuning #'s

After Kooks and tuning, converter locked and unlocked:

How much did your setup cost? I don't have any emissions testing so I wouldn't need cats. Do they have any off road X-pipes or H-pipes to work with those? Also I'd like to go with probably a Corsa exhaust...would that work?

I can't speculate on the difference between the cats.I really don't know...

I never had a problem with my Mac cats, and I never was convinced they were not up to par.

No suprise here. Mac headers are very good, the cats are not....
