so i called Thermal, 97 civic EX is 91db at 18 inches from the single 4" Tip at a 30 degree angle, with 7-9% gains (no hard facts because as u add more mods the exhasust HP keeps rising)
HMmmmm all Stainless starting to sound Good,
Hks Hiper is very close to 95db at (5-10 hp) and the SPort passed with flying colors around 90db (at 5-7 hp) NOTE: THermal had nicest Customer service rep PLUS Cheryl sounded HOTT
James at HKS was an ass and wouldnt look up anything, he gave me round about numbers from his head.
I call RS*R and Ben was very helpfull! (cheryl still wins though cause she is a CALI gurl) RS*R ex-mag series has alot more back pressure because they have a baffled muffler, there fore increasing torque at lower rpms, they have best response from 2500-5000 rpm (which will help me to stop RED LINING EVERY GEAR)
they have ruffly 5-7 hp gain throughout
SO now, do i want a baffled, low end, more torque exhuast or do i want an ALL stainless Steel muffler (=more hp), higher revs (the way i drive), with slightly higher HP gains, but SLightly louder?
SOMEoNE with a THermal PLEase Drive through MASONS campus so i can hear that SH*T.
