DEEPEST SR exhausts

[dankS14]

hey

first, yes i searched!

right now, i have a redtop SR with basic bolt ons...my exhaust setup is HKS downpipe, test pipe, and apexi dual N1s..

i was wondering what exhausts out there are deeper than the dual N1s..i like the sound of it, but i want it more aggressive sounding(deeper)..i have heard the greddy DD and the RSR GT2, and both sound deeper, but louder...

i DONT care how loud it is, i just want it deeper than what i have...from what i have heard the trust DD/PE2/TR EVO 2, RSR, and the GT spec are some of the deepest...is there anyone who has heard multiple exhausts that could give me their opinions on the different exhausts, regarding the deepest...i just wanna weigh my options and see what is out there...any opinions and advice are welcome...has anyone heard JIC, uras, GP sports, trust PE2, trust EVO2, RSR, HKS, ETC...

also, what exhaust has good clearance for lowered cars??i scrape my duals everynow and then on speed bumps...
