i need a favor.

i need to know what length of pipe is between the resonator and the flange that bolts to the downpipe. the catback i bought was welded on to the original owner's car, and im rebuilding it to factory standards.

i also need to know how long the downpipe is AFTER the bend to the flange to that attaches to the catback. i have a shorty dp and need to know what length of pipe to weld to it.

thanks in advance!
