I'm doing a Eagle swap into mt '73 AMC Javelin and am currently looking at how to route exhaust under it before I finish up my trans tunnel. I'm using OE SRT shorties and they measure 2.75" ID. Would 2.5" be adequate or should I go 3" back to the mufflers and 2.5 tailpipes? I'm going to have to use oval pipe since clearance is an issue. This is a street driver used for long hauls so wringing every bit of hp is not my main concern. Thoughts? Suggestions? Thanks.
