guys im still trying to decide on an exhaust set up. i made a mistake the first time, and i dont want to do it again. i was wondering about the volume of the slp long tubes and their shorty x with cats. i would mate this with the magnaflow catback to try to keep it quiet. i have a bassani o/r x pipe, and 40 series flows. would slp with magnaflows be quieter or louder?
also do i need to get a tune if i go with long tubes or do they bolt right in? i heard that some people get a rough idle or run rich after install.
