I have an SR20det in my car, and the exaust is all 3", with a hollow cat, and a straight through spiral lined muffler. My car is the kind of loud that makes pedestrians turn around to see what's coming, and people in their yards with kids to give you the two hands up then down symbol that universally means, "slow down", when you're going 25 through their neighborhood.
I would LOVE for it to be quieter, and ideally without sacrificing a great deal of power/efficiency.
Does anyone have a 3" muffler they recommend to perform this duty?
I have the same car, same problem as you, Qbart007, a very loud exhaust left by the previous owner (bullet exhaust, I think). everyone can hear me coming, speeding, shifting, mis-shifting(embarrassing).- For now, I wear earplugs when I drive, especially on the freeway.
I'm sure I would thank you, if I could ever find one.
BTW guys, about "r-spec" exhaust, its crap. Im trying to return it. It turns out it is actually 2.25 piping with a 4 inch tip- and the piping bottlenecks down to 2 inches at the bend. theres wire mesh sticking out from the resonator- looks like a bird nest in there. and theres a wrong-size flange welded off centered that I cant fit a bolt to secure it.
