To CAT or not to CAT...
that is the question.
The GTP'* debut is immient, and I am doing a lot of research on mods. I have been looking at downpipes.
I really like what R/T offers. They have a 3" DP with high flow CAT that shrinks down to 2.5" so not much torque is lost. Then there is a 3" to 2.5" DP without a CAT. I am having trouble deciding between the two. Michigan does not have inspections, so I do not have to worry about having a CAT or not, but I am wondering which direction I should go.
I am leaning toward the CAT-less DP because it is cheaper, but I'm not sure.

youll most likely lose alot of torque with no cat. I went with a high flow cat and had very little change in performance but alot in sound. Id go with the cat.

Unless you're planning on MAJOR 13-second mods, don't even think about it. Now consider the environmental aspects, and the fact that it'* very difficult to find a shop to do this. If not impossible.
Keep the cat. You'll never know the difference. Hi-flow of any brand.

I was thinking the same way not too long ago when I knew TOGs where going on. At first I was leaning towards no cat, try to find a shop local that will do this, I couldn't so, that left me with a hi-flow, got an SLP. So from tog flexpipe is 3in and dosen't reduce till after the cat.
But since it is a GTP don't they bolt up. If your handy the choice is yours.
Oh ya and In IL theres some mult- thousand dollar fine if your caught. Check the law in MI

Everyone else has stated what I believe in firmly, and with a performance exhaust, you will feel the HCF, if yer in the mood to remove things, remove the U-bend
