RNR exhaust questions

[sting0004]

I have a 96 stock gst spyder right now. My goal is to run low 13s to high 12s. I am looking at RNR turbo back exhaust. Any comments on this exhaust? There are alot of options. Should I get 3 inch or the 2.5 inch with an O2 elimintator housing? I cant get 3 inch with the O2 elimintator becuase its expensive. If i get the 3 inch i could port my O2 housing to like 2.5 inches anyway. Are there noticeable differences with the different set ups? The site also says add 50 dollars for a stainless steel muffler; is the muffler that the kit comes with really shitty? And there is no catalytic converter right? Thanks for any help, Matt

I've herd It is a very good choice , and well built . I'll be puting on a full stainless 3'' turbo back 02 eliminator with external dumpthis spring.

I've got the 2.5" O2 eliminator turbo-back. I have the SS muffler and do recommend it over the standard one. I haven't heard the standard one, but the SS one sounds good and looks a lot better. Not just cosmetically, I mean, it looks like it is a better quality part. I saw both of them side by side at RnR when I lived in San Diego.

BTW, I did a full review on this exhaust at DSMtalk in the Parts Review forum a while back, if you want to search for it...
