Displayed in these pictures are various nitro pipes, i.e. 7.5 OPS pipes #1, #2-SOLD, #3, then #4 is one 11cc OPS & #5-SOLD is one 11cc Mac pipe. Silencer #6-SOLD fits the 7.5 pipes & #7-SOLD fits 11cc pipes. I will mix and match by selling the pipe, silencers $10.00, & 11cc pipe bracket $5.00. In summary, they can be purchased separately, or with different pipe(s). The prices are as follows for OPS pipes, less silencers & bracket: #1 7.5cc OPS Pipe $15.00, #2-SOLD 7.5cc OPS Pipe $15.00, #3 7.5cc OPS Pipe $10.00, #4 11cc OPS Pipe $20.00 & #5-SOLD 11cc MAC Pipe $25.00. Then displayed in the remaining two pictures are larger Mac nitro pipes, i.e. #9-SOLD 13cc $15.00 (1-Dent) & #10-SOLD 15cc MAC $35.00 in good condition with no dents. In addition, silencer on 15cc is $10.00-SOLD & pipe mount $5.00-SOLD. ***The first to say "I will take it" gets first shot to purchase what they want and then second in line etc. Prices are outlined plus actual shipping.
