Subject: Re: Interior resonance / exhaust drone... by Ultraman on 2014/8/25 12:39:23 When I had my 90 L98 I put headers on it with 3" cats hooked to the collecters and then down to 2.5" back into an X pipe and on out to Sound Master mufflers from NAPA....not very sexy on the mufflers but it sounded good and had no drone at any rpm......and only 96 bucks each for the sound masters......of course LT1's are a different cat altogether...... |
