can anyone tell me the size of the exhaust piping on a 03' BJ 1.8

dfvadr · 18-10-2003, 02:18 PM

i think 1.1/2" to 1.3/4"
dont wanna 2.5" sports system cat back do you

na 2" will be enough for me

2 1/4 would be a better choice for a 2L motor. I think if you get your
current exhaust checked it will be propably 2" as my model was a 2"
press bent exhaust up to the rear muffler and then a 1 3/4 from the
muffler back factory so the 2L would be very close to that. Only going
2" would be a waste of money even a mandrel bent one sooner get
a 2 1/4 press bend as cheaper.

Regards
