I currently have lt's, catted y, and magnaflow catback.

I was wondering, whats the best configuration?

1) LT + catted y + catback
2) LT + ORY + catback
3) LT + catted y + electric cutout + catback
4) LT + straight pipe
5) LT + gutted cat + catback

I'm looking to get the best performance, but not something that will mess up my engine. I live in a smog free county I know I would need a tune with any setup, and mine is currently tuned to my current config.

Any advice helps, Thanks.

My cat was literally welded in, if that helps. I'm leaning towards with going with a cutout installed hmm so confusing

What you have, with an E-Cutout. If you want to gain a couple of horsepower, ditch the cats and get a nice merge.

It's not worth switching from what you already have, unless you are after every HP.

LT + true duals (NO cats) would be my vote though.

To ask a stupid question,
if i go with a ORY pipe, will it mess up my engine? or is it totally safe.

I don't want to start a back pressure flame war, but i read mixed reviews from various forums, just need some advice.

btw thx for the replies

It won't mess anything up. Just might need a little change in the tune and the codes deleted. Do you have a Kooks catted y? If you end up getting rid of it and want to sell it, shoot me a PM. This goes without saying, but the setup you have now is what I'm after, so I'd keep it the way it is and maybe just add an electric cutout.

If you go ORY, you need to tune out your rear o2's (or find someone who still sells the false o2 sensor plugs) but other than that nothing bad will happen.
