the title states cat back exhaust...
i would say neither, just get a 3" dp and 3" midpipe, with an exhaust cutout ;D
Im thinking about doing a cut out, any suggestions on brand? I hear horror stories of them seizing up and thats NO GOOD!
There's two types of people who have cutouts. Those whose already leak, and those whose will eventually. Lol, I thought about doing the cutout thing too but didn't read very good stuff about them (leaking problems).
Cobb's TBE is supposed to be quiet and probably will be the most 'liveable". I think at idle it's actually quieter and at WOT not much louder...sounds nice though. Their WRX system is around 1225 though....and the MS3 may cost a little bit more (has muffler and resonator vs just muffler for WRX). Corksport's TBE is like 800 when you buy it all together. I've PMed a couple people who have the corksport TBE and they have all said it's not too loud or anything. One person liked it a bit more keeping the stock mid pipe (cat)..said it wasn't quite as loud. I'm probably going to get a high flow cat for the mid pipe, that might quiet it down a little. But... I haven't got mine yet so I don't have any first hand experience for ya.
