Default Side pipe question
75 corvette - Going with stock manifolds and stock side pipes – Question on the heat risers, I would like to eliminate them and go with spacers – Do I need a spacer for both sides or just one?

Thanks Mike

You should only need a spacer for the passenger side...

Are you using C3 factory side pipes?

Good luck... GUSTO

You can just grind off the screws / rivets on the stock heat riser and remove the plate and it will look stock.
