Exhaust Swap.
suppp.
bought a piper system off jonathon5 for a nice price and fitted it yesterday and it sounds awesome.
step 1, rip off old powerflow piece of shite and compare to piper
step 2, examine old exhaust for signs of good workmanship:
none found.
step 3, fit piper system:
great success! 3.5" inward rolled backbox, 2" pipework all the way back to manifold, car is now decatted and sounding larvely.
vv:listen to it:vv
Ignore the smoke, coming off the exhaust paste.
