Well I'm finally getting around to ordering parts for my 69 L36 body off resto and I have some exhaust questions. Why did they use 2 inch exhaust in 69? Would I notice any difference while driving with the 2 1/2" exhaust and which would you all suggest that I use here. I'm doing the resto as close as possible to original with the judging guide so that makes me lean towards the 2" but since all the repro exhausts are stainless or aluminized,it won't be correct anyways so this makes me lean towards the 2 1/2". What do you judges think about my options? So far all that I have decided on is to get the welded muffler and rear pipe style. I'm really split on this one so any thoughs on this would be greatly appreciated. Thanks
