Accurate ltd 273 hipo exhaust????

Anone use the Accurate LTD exhaust system- seems complete front to back.
If so, I have a couple questions?
Do you have to cut the rear valence?
Use with 7 1/4 and 8 3/4 rears?
Price is $895- a lost for single exhaust- but then there has been a NOS resonator for $759 on ebay for months- but then-not sold.
Anyone use the resonator that Dale's Cua sells?
Thanks,
I am planning on using on my '65 signet


Tom sell some good quality stuff. Considering nobody else sells the resonator that is close to NOS Tom gets my vote. I have the single modified Y-pipe on my 64 vert and the resonator. Also using the resonator on my 64 post car. both have 8.75 rearends
