H pipe with or without cats?

I put in true dual Spin Tech Pro Streets 3 weeks ago, but made 1 mistake. I didn't put in an H pipe. The exhaust sounds nice and loud, with a good rumble from 0-50, but a little raspy at the higher RPM's. And now that I put in a 4.10 rear, she runs about 2700-2800 RPM's at 70. Everyone says I should put in an H pipe, it will give it a deeper rumble. My question is twofold. 1, cats or no cats? I've heard no cats smell bad and add to the raspy sound. Also heard need cats for V6 back pressure. 2nd I had a muffler Guy tell me all he would have to do is place a pipe between my existing pipes and it will be the same as an H pipe. Is that right? Or should I actually buy an H pipe? Please send me all your advice and opinions. They will be greatly appreciated, Vic.

Re: H pipe with or without cats?

depends on the diameter of the pipe and the aftermarket pipe. Not sure what it is on the stock pipe but if its the same size as an aftermarket you could prob just gut your cats instead of welding a piece of pipe between them. but I'd say do it right and just get an off road h pipe if your looking for a deeper sound, x pipe if your looking for a little more power

I have no cats and it sounds pretty good. I have BORLA catback stingers too though. I don't notice any bad smell.

Re: H pipe with or without cats?

BTW you can just have a pipe welded in place.

Or am I? But yes you can just have a pipe welded across for very cheap. About 20-50 bucks depending where you take it, 50 would really be on the high side since it's just a small straight pipe, and takes less than 10 minutes to do.
