Thanks guys, keep them comming.
About the N1s, I know that they're loud. However, I'll be having the giant Resonators (not glasspack) right before them, and an H-pipe before the resonators, should be good

.
Btw, this is a True Dual headerback setup with H-pipe.
I'm contemplating on whether I should get the HKS Hi-Power TI since it has a nice looking Ti tip

hfawk: or go withthe full carbon-ti

too bad they're at much larger piping than what I wanted. Sure looks sweet.
