My girlfriend just inherited a sweet 85 5th avenue. Did the brakes and got her purring. It has the stinking converters on the y-pipe right at the manifolds and the passenger side is clogged up and glowing. Found a new y but it says canadian emissions only. We dont have emissions here and the new pipe has no converters. Any reason that pipe wouldnt replace the one on it with the converters? Its a walker part # 40430 if that helps, Thx.
