S shadowland2000 Member Mar 28, 2003 97 0 6 Mar 6, 2004 #1 Mar 6, 2004 #1 I have an 01 cobra with about 13500 miles. Only mods are K&N and FR500 catback. I'm using So Cal gas (91 Octane). I'm getting major pinging from the exhaust on WOT. Is this normal? Is there anything I can do such as maybe a different exhaust system? Thanks

S shadowland2000 Member Mar 28, 2003 97 0 6 Mar 7, 2004 #4 Mar 7, 2004 #4 This sound definately seems to be coming from the rear exhaust pipes on hard acceleration, particularly in 3rd or 4th gear. I call it pinging cause it sounds alot like engine pinging.
