I bought the borla catback for my 8. Should i weld it in or not? I dont want a moisture or noise problem. But is it necessary? I only came across one thread about the borla + welding so i wanted to get more opinions. Thanks

no one?

I don't see a need to weld any exhaust..spare some junk muffler bought on ebay. just use all the gaskets and you'll be fine

<-- 20K with my HKS, no leaks
