2 pipes a novarossi engine owner should have.. after my 1 year of testing.. 9901 and 2096.. with 21 header... and
maybe the 05 and 01 [ shape headers for tuning options... no real need for the 20 header.. those 2 pipes were just fantastic in truck or buggy.. depending on track.. no matter what engine... for me was plus 4C, FMS, FMS HT, X7 HLX...
