Before full exhaust replacement on GPGT:-15.457@88.17mph
After:
zzp ported manifolds=$250.00 bucks
2.5 custom downpipe/-w-
Carsound "Magnaflow" hi-flo cat=$70.00+$45.00 for instalation(included downpipe)
2.5 cat back=$100.00
original u-bend and resonator delete=$60.00
Sumitt turbo muffler=$15.00
total=$540-(minus the 60 that the bonne won't need for u-bend delete)
new time in the quarter= 15.088@90.20mph
mind you this is on aa N/A engine. Hope this helps with your question.
