i installed the new heads, cobra intake,1.7rr's ,Maf,65 mm TB and shorty headers yesterday.The performance gain is great but the car is quite a bit louder than before especially the drone.My wife is not impressed.I have the stock h and the Magnaflow catback was on before.Would the headers make that much difference or is it something else?


). Her response when I lit it up for the first time..."Well I'll always know when your on your way home, and why does it sound like it's gurgling"..by that she meant the cam loping...her last statement before going back inside with barely a smile.."Your shaking the house and you've scared the dog, can you shut it off and come in now?"..what a great woman...she really is though.
