freefallin98

Ok so I was complaining earlier about how my engine was like "popping" when I hit about 4500 and on RPM's...well today its still doing it and I can really hear it coming from like right under my feet and it sounds like the headers, o/r/ h-pipe, or exhaust or somethin and it really does feel like it is robbing power a ton.....so I really hope some of you guys know what this is....my car is a 98 GT by the way lol. So PLEASE help me.....skipping, popping, idk what it really is....I just want to get it fixed...could it be a header gasket or something? Thanks, Sean

If you described the problem a little better, you might get an answer.

when i had my magnaflow cats welded in my h pipe, the bastards used a hammer to make the cats clear my fram. so now at certain rpms the ctas vibrate and rattle against the fram. dunno if youve had exhaust work, but thats just one thing rpm related.
