After consulting with muffler man Aggressive Ted via PM, I decided to spend some more dough to quiet down my car another notch. When I purchased this car in spring of ’08 it had 2†duel exhaust from Clifford headers to rear bumper sporting a pair of twenty year old Turbo Sonic mufflers; the noise was unbearable requiring foam ear protection on any trip longer than fifteen miles; and the drone... oh god it was dreadful.
After spending money on more important improvements than noise abatement for several years, the turbo mufflers were replaced with a more [url=http://www.summitracing.com/parts/wlk-22052/overview/]OEM type units[/url] that enabled one to drive without hearing protection. Still these mufflers did not kill that obnoxious /6 2500 rpm drone only knocked it down a bit, or the angry bee finger nails on a black board sound one of these engines generates when compression is been bumped up.
So today following Ted’s direction, I installed two 12†Flowmaster HP2 mufflers upstream from the current Walker mufflers. What a difference, as Ted said the high frequencies are gone, mid 2000 rpm head splitting drone gone. Squeaks, rattles, rear end gear hum, poly UCA bushings, and wind noise now dominate the cockpit with top up. A much more mellow pleasurable tone is being emitted from exhaust pipes. The once quiet 3000 rpm range is a new noisy zone from possibly excess fan noise, something that could not previously be heard over the exhaust racket.
So I’m thinking an electric fan is in order to make this car a better top down cruising experience.
