Scooby, if you want to replace the stock resonator, I agree with Aussie. I have looked through the Eldebrock and it is an excellent design (trust me). Very straight through, non degradable ceramic packing surrounds straight through "dual" path core.
The Moroso part is center inlet & oulet. Unless you modify your pipes you need offset inlet / outlet. I looked at this with resonator I put on the Bassani (I needed a small center in /out so the Eldebrock was too big). The Banzai I got is real nice but will not work for you.
