Thanks. I used hi-temp anti seize on all fittings and threads. I have a bit of a Frankenstein system, but it all fit together very well and the NOS muffler sounds perfect IMO (Thanks Bob!) I used Fuller tailpipes and reducers(eBay), but the economy resonator pipes and h pipe. Using the better AMK clamps was worth the extra money since they have locking nuts. One mistake was I forgot to put the horseshoe clamps on before I installed the reducers. Now, there is no way to get them on with everything installed. The geometry of the economy exhaust hanger J clip is incorrect - it would have been worth the money to buy that item from Scott Fuller. Thanks for everyone's help.
