Anyone used this with a turbo application and/or a N/A application? Its basically going to be my exhaust for my stock piece o' crap and my swap coming up in the next month or 2. Quiet is a really nice characteristic. If this comes in a 80mm only type, will I lose a lot of power from such a large exhaust on my N/A....can't really afford to lose more. lol. Any help is muchly appreciated.
