I need a new exhaust bc my universal apexi n1 is blown. I was gona get the n1 catback no problem but i think lowered 2 inches its gona scrape so thats pretty much scratched. Now I am left with the following. I want something deep and not TOO loud
1. Apexi ws with test pipe( no more cats, they always blow)
2. 5zigen fireball with test pipe
3. RS*R gt11 with test pipe

what do you think will sound best. i have dc headers and intake too. Where can i get a resonated test pipe? If you have other suggestions please feel free.

 

apex'i WS

 

would the ws get a little louder with the test pipe. I like the exhaust but wish it was a tad bit louder but not much. Will the test pipe make it deeper? and would it ruin the muffler having a test pipe.
