Well i dont care to make my car quieter i really just want to get rid of the trumpet sound it makes, , i just want to get rid of the annoying trumpet sound it makes after 1800rpm. my set up is TSP 1 7/8" longtubes, tsp ory pipe, and LM2 catback, Now would it get rid of that annoying trumpet sound if i got one of those slip fit spun cats ? i dont feel like spending another $350 on a tsp catted ypipe.

I was thinking this cat ? http://www.jegs.com/i/Magnaflow/642/59929/10002/-1

Put a resonator or chambered muffler in there somewhere.

Soo its ok to run two? Since i have a lm2 on it?

Maybe swap out the lm2 resinator for a magnaflow muffler?

I pretty much have the same setup OP, but only with a LM1...which is worse actually lol! I am looking for something cheap, and have decided on a Flowmaster merge pipe along with a Magnaflow 14419 muffler. Have you considered that?

I was just thinking about adding something on or swap the lm2 muffler out. Just wondering if a magnaflow bullet will do the trick even though im running no cats.

I'm sure it will help a little, but maybe not enough on it's own

Soo the magnaflow 14419 is the bullet and 3" is the right size to fit on the loudmouth catvack or ory pipe?

I'm not sure on the "exact" dimentions but I do know it's very close and can be done. A few on this form have swapped out their LM 1 to this

Magnaflow will make a huge difference. I had LMIIs dumped before and went to a 4" over the axle with a dynomax bullet in the I and a magnaflow in the stock location. Quietened it down a ton. If you have room I would run two mufflers. If not just replacing it with a magnaflow will tone it down.

OP yes get the magnaflow bullet and ditch the loudmouth II. They really only sound good with stock headers.

Soo ill pull of the lm2 muffler and get that magnaflow bullet. Now what size will i need to fit the lm2 batback?

There has to be a 1000 threads on this topic.

The sounds you are referring to is a result of the exhaust design. The way the pulses are coming together in that rpm range is causing a resonance. Cats will hide it, a better merge wil decrease it, an different muffler may hide some of it, but the only real cure is a tru dual exahust system.

You want the 14419 Magnaflow OP

I would chang the muffler. I sounds like a glass pack muffler. Put a flowmaster on it
