not going to make a difference, except on the thickness of your wallet

LOL right!

You can lose a lil bit of torque depending on the type of muffler. When I went from the mac cat back(regular mufflers) to the slp (basically resonators) I noticed quite a difference in low end torque.

LOL b/c my car is the shyt and I like how they sound! If you want SLP's get the 2's or the power flows.

Yes, you are wrong. I lost some low end torque.

Aww, da*n it all, I just got some SLP LM1s for xmas..... I have to have cats and the flowmasters weren't that loud so I went with SLPs. Guess I'll just have to like the sound and deal with the loss of torque.

Magnaflow for power. I noticed a little less low end torque with the Magnaflows over the Flowmasters, but it makes more power from about 2500-6000rpm.
