Exhaust advice
1. Which is the loudest of the two?
2. Which is the best flowing of the two?
3. In your opinion which sounds better with Long tubes?
I am looking for intimidating note from my exhaust and dont really care a whole lot for the Loud Mouth, so out of these two exhaust which would help me achieve that note? Thanks for the advice!
If you are gonna go at this systematically which it looks like you are doing.. do it once and never look back.
Go QTP or Kooks Long Tubes, True Dual Mandrel Bent, Corsa exhaust tips.
Yes expensive.. but if you look at it this way.. alot of people (me included) go mac midlengths and y pipe with cats and a good catback (lets say borla). Thats ROUGHLY 1400 plus installation.
Then you decide you want to scrap the headers for long tubes and you go with qtp's.. thats ANOTHER 700 bucks and you need a different y pipe and you go with theirs.. 525 right there. So another 1250 for indecisiveness. Then at the end of the day you decide true duals to just get it over with and not have hanging low issues. Another 1500 bucks
You JUST spent roughly over 4 grand for true duals lol!
And yes, this actually happend to me

So my advice.. true duals with a GOOD long tube.
If you do choose to stay with a Y-pipe set up, my brother is running Corsa with SLP headers and sounds awesome you will not be disappointed. However 99% of the members on here regard GMMG as the best cat back exhaust for an F-body.
If you run cats you will have a chance to pass emissions but will of course depend on what state you are testing in and how well you know the shop manager.
I have high flow cats on mine, my car is quiet at idle (still sounds good) but at WOT it is beautiful. Of course that is how I wanted it.
