Hi guys, sorry if this is a noobish or annoying question, but I've been searching and can't seem to find a positive answer. I wan't to run a higher-flow exhaust on my 2014 STI, but, where I live if I do anything to make it louder I'll be pulled over almost daily. I was wondering if anyone has hooked up a COBB (or any other brand really) downpipe to the stock exhaust system? Is it safe for the car, and will it be able to handle more power without replacing the rest of the exhaust? After I figure out what to do with my exhaust I was planning on investing in a front mount intercooler, headers, an up-pipe and fuel pump (I already have a CAI), and just want to find out if this would all be reasonable or safe with only a downpipe. Thanks for any help in advance, and sorry for the noobish question! I wouldn't have asked if I hadn't spent plenty of time searching already!
