Here goes the parts list for the stacks:
Purchased from
Berubes in Bow, NH.
2ea, 4"x48" curved stacks, straight, no flare $61. 85 ($123. 70)
1ea, 4"x8" ID/OD elbow $20. 99
2ea, 4"x10" ID/OD elbow $21. 01 ($42. 02)
1ea, 4" Y-pipe $63. 90
1ea, 4"x12" stainless flex $12. 05

8ea, 4" *preformed* Torc-Tite band clamps $7. 72 ($61. 76)
2ea, 4" chrome clamps $9. 78 ($19. 56)
4ea, 4" clamps $4. 38 (17. 52)
1ea, 3"x4" OD/OD reducer $10. 19
Other parts used that I already had from another project:
2ea, 3" band clamps ~$7. 00 ($14. 00)
1ea, 3"x24" flex ~$12. 00
Note, as far as I know all of the parts purchased from Berubes are made by Grand Rock. I used the 4" stainless flex in the bed because I can't find a shop around here that can expand 4" pipe. ***Use preformed band clamps, the other ones don't seal worth a crap and they will crush the flex pipe. *** Also, the aluminized flex tends to rust real bad, so I'll be changing that piece under the truck soon.
Cheers,
