First, no issues reported with the installation from tech. at Tischer Acura (Laurel, MD). Everything went super smooth and the tips sit well in the rear valence. The engine definitely is running smoother, revving a bit faster and feeling peppier. Sound is loud (for me personally) even with the inner tube silencers installed but everyone at the shop loved it (without silencers of course :biggrin. I hear it in the car unless I'm just cruising. According to Taitec, the difference is 6 db (GTLW Only = 106 db, GTLW + Inner silencers = 100 db) which is probably not a whole lot of difference. I have driven 20 miles since yesterday but I can feel some power gain. Will update in a few weeks if anything changes. One thing for sure, the car's lost 40+ lbs :biggrin:
