Default What kind of HI-Flow Cat should I get?

I am having somewhat of a hard time deciding what hi flow cat to get maybe you guys can help me. Currently the exhaust is fully stock and I am not changing the mufflers or taking off the resinator. But of coarse I will be deleting the u-bend with this little project. Now my thing is what hi flow cat can i get that won't make my car louder or minimum. I have heard good things about magnaflow but I dont know about the noise level with that. So what do you guys think?

If you are wanting to do u-bend and have high flow cat, do a random tech downpipe. With the stock mufflers and res still there the car is not going to be loud. Even if you did take the res. out, it will be a little louder but more of a deep quiet rumble. Wiz kidd had high flow cat and res. delete on his Monte and from what he said it sounded good, quiet but nice deep rumble.

I have the Random Technology DP along with SLP cat-back. With the u bend delete and no resonator, the HP increase was very noticable, and the sound is great. Its deep, and not really loud, but there is a constant roar inside. I assume thats from the res delete, though.

There's no sense in doing a hi-flow cat, and keeping your stock resonator.

You're not going to gain anything in terms of performance, and if you do, it won't even be noticeable.

ZZP has a good DP and HF cat combo that includes the u-bend delete. The random tech ones tends to have the small little cat that ends up coughing up a hairball sooner than expected. They have shorter lives on average.
