I have that exhaust on my car. I dint get the polished one like in that pic. Mine is gray with chrome tips I like them because they look stock and arent as loud. I have RB Header & presilencer too. It has this deep tone to it and sounds pretty cool at WOT. I dont think its loud. Heres a pic of the exhaust on my old FC:


Heres an old crappy clip. You can hear my exhaust pretty good. I hope the clip works for you.

ok thanks my rx-7 looks like your gxl same color too

 

wan how much did you pay for the exhaust

 

uh... The whole package (RB header + presilencer, hks exhaust) came out to $1000. I think I bought it a little over a year ago. How much does the "kit" run for now?

 

how much did you pay just for the hks exhaust

 

I dont remember the exact price. One of my stock mufflers was falling apart. I was on the freeway and the exhaust tip fell off My exhaust sounded like SH*T!! I basically walked into Mazdatrix, and bought the whole package without even asking for the price hehe.

Just subtract the cost of the RB header and presilencer from $1,000 and you should end up with the exhaust price.
