I installed my h-pipe last week, and I really like it. I had the two pipes welded together at a local exhaust shop (he did it for free - pretty cool guy). He said he didn't think I have any exhaust leaks. My question is, only under hard acceleration I hear a noise other than the normal exhaust noise. I don't think its pinging, but I could be wrong. Could the H pipe cause my car to ping? I'm going to try premium next (the noise is still there with 89 octane). I did not have this noise before I put the H pipe on. Maybe this normal w/ the MAC H pipe? I really dont know how to describe the noise. Its not really a hiss. It sounds like its coming from the h pipe area.
