Is $95 for a flowmaster installed a good price? Is the flowmaster louder or magnaflow? Also does anyone have the gibson catback?I was looking at the borla set up,but toooo expensive , but they have a universal muffler that u can ask the muffler guy to do the set for alot less.The muffler guy told me dual exhaust is very loud , is it? I just like the look. any comments would be appreciated. I also asked before is the taco 4.0 the same as the 4runner if so do they use the same headers.
