Well thats thats the cobra decays fitted, OH GOOD GRIEF. It would blow your ear drums out. There is a little drone between 1800-2300rpm but the rest of time its a deep burble at idle to all out screaming at full chat.
Your correct oldbonesmcgee! It is almost deafening. I normally love the louder the better but even by my standards, its brutal.
I had so much trouble getting the short tails on due to rusted bolts, I needed titanium drill bits before cutting the bolts, then drilling out the flanges. I am extremely handy, but due to trying to work on my back under axle stands, I gave up with the decats and went to a local shop. They had so much trouble, the last bolt on the manifold side was stuck, and they had to disconnect the steering rack to get access. It was an awful job, best £80 I ever spent!
