I removed the OEM tips and welded on these 3.5 inch polished tips. They are a no name brand but high quality, they look exactly like the ones that Racing Beat uses. Not sure of the inlet size but it did require a small coupling. I believe the length was 6 inches. Had them tucked up as close as I could to the bumper and as flush to the back as possible. I think they came out great and am happy with the installation.
Check those muffler prices again. I believe they're both considerably less than $600! As for the tips, I have two suggestions. I put 4" Flowmasters on mine and wish I had gone a little smaller. I think the 3.5" look better, but if you go with the 3.5" you refer to on ebay, don't install them over the existing tips like someone else did here. Cut the tips off and install them on the remaining stub so that the old pipe does not show. BTW, Racing Beat makes superior products. If I were to replace the muffler on mine, I'd go with them in a heartbeat! Have used them on both my Miatas.Can't decide between tips but I really like these 4" Flowmaster
and maybe these 3.5" ones from eBay

Would also like to change the muffler for a little deeper sound. RB and CS have nice sound for $600 but has anyone tried custom cat back on a budget?

I also change the exhaust tips after reading on here.
I removed the muffler when I fitted the towbar(hidden type) and measured the new tips,cut the old tips off and welded the new larger type on.
Replaced the muffler-like the look now.
You made the right choice. I was an "early adopter" of this mod 2.5 years ago and used 4" tips. Although I wouldn't call them "ricey", they are a little bit disproportionately large to my eye and I wish I had gone 1/2" smaller. They weren't cheap though, especially with the labor charge, so I've never really considered changing them out.Didn't want to go 4" and have it look to "ricey"
