Borla Resonator and Resonance - ZR-1 Net Registry Forums

emmvette · 04-05-2018

My car has the Borla exhaust system which was installed by LPE in 1997. At the same time LPE installed custom fabricated headers. Cats were removed this past year.

The car is fine for spirited driving, but with a 2+ hour drive results in a headache from drone. When I tap on the resonator; it sounds like an empty tin can. Is this normal, or is there some baffling missing or burned out?

Does anybody know if the Borla resonator had baffling or if it was just slotted pipes on the interior? I'm wondering if mine is "worn out" or needs to be replaced to cut down on the drone at highway cruising speeds.

Let me know of any thoughts. Borla doesn't make the resonator anymore and I don't see any replacements with the same pipe centerlines. Any thoughts on this?
