teenv6 said:So no matter what I get LT or shorties, they are gonna sound the same, but with performance wise I want to get shorties?
Ok, what is the difference between the H-Pipe with the cats and without the cats, performance wise and sound wise.
This is my last question.
Thanks ExEffect

We have 4 cats on our cars, I was going to get all of them taken off but the guy at the muffler shop told me that emission test were coming back this year so he told me to leave the top two of them on so I would pass. If you wanted to, you could get them gutted and it would look like you have them but actually you don't. I hope I helped you out a little here. Oh ya, I am not sure about the sound but I think its a little louder without them.
teenv6 said:Thnx... still curious of the sound difference with or without the cats on the h-pipe
teenv6 said:Ok, I'm running into a money shortage, so if I just get the headers and not the H-Pipe, that will still make a nice throaty sound with the MAC shorty headers, and the cat back exhaust system, right?
DcDisturbed947 said:no...the h-pipe is what'll make it sound better. I have this setup, mac catback, offroad h-pipe, no I only took out 2 cats, not all four, and at low rpms it sounds REALLY good, of course not as throaty as a V8 but pretty damn good. Now once you pass 3500 rpms it just sounds like total crap. So if you can keep it under 3500 you'll be 100% satisfied w/ the sound. The headers are not gonna make any sound difference, and IF you get any better performance with them, its very minimal.
teenv6 said:So you have the H-Pipe without the cats? I'm asking, cause you said you took out 2 cats, and I was thinking if I did the same setup as you, why would I get the H-Pipe with 2 cats, if I am gonna take out 2 cats anyway...
So is it safe to say, I can get the H-Pipe without the cats, as long as I don't cut any other cats off, so I can pass emissions? If I'm wrong, someone please correct me... Thnx
DcDisturbed947 said:I took 2 out of the 4 cats out. It is illegal, big fine actually, but I live in Florida, no emission tests. If I could go back and do it again I would've kept the cats on, or gotten the h-pipe with the cats. The 6 cylinder doesn't sound very well without the cats. Get the H-pipe with the cats, you're better off that way.
