1997 I6 C280 the the best magnaflow muffler?

[anf6789]

mine barely droned. i liked the tone it had. and i wanted it louder and smoother so i put a magnaflow resonator in as well. I remember when i first got the muffler installed i thought it was too loud, but then it grew on me and i loved it.

It only drones below 2500 rpm, and if you go above 3500 it sounds amazing don't get me wrong but i just hate it when i push the gas after a complete stop like red lights or stop signs. it feels good when i'm cursing and i take the foot of the gas, is quiet. I wish it was like that when I get of a complete stop. Anythink I can do? I will but back the OEM air filter even though is dirty and now I have a K&N drop in, and I have a little dynoliner i'm gone put in the trunk to see if it will change anything.

So a friend of mine has been researching somethign called a Helmholtz Resonance Theory.. and its pretty popular topic in the camaro/corvette/trucks scene. It seems like a easy thing to do, except for measuring the pipe length. People also name it T pipe or J pipe which you add a capped pipe to your exhaust to eliminate the drone, depending on your drone RPM range, the pipe size will vary. there is a formula around the net too.

Here is a thread that has many camaro drivers doing the J pipe/helmholtz theory and seems to work for them.....
