forgot you had the curved oversized...very nice!
If I wanted it accurate for the early G, I would have to buy the triple exhausts and chop it. Or, as you indicated, buy two sets of the Panther A and just use the single stacks from both sets. (gives me an idea...offer the Panther A exhausts in two formats: as a set with the single and triple stacks (like shown) and just the single pipes as individual pieces). BTW...are the Panther A exhausts functional, meaning the smoke goes in the bottom from the inside and comes out the top of the pipes?
At the end of the day, though, you have covered the exhaust options if all three types shown can be purchased as separate sets.
