I finally decided to go with a full Mac exhaust. Longtube headers, pro chamber, and axle back. My only question is I'm going with an off road pro chamber, but I'm thinking of ordering slp highflow cats to go with the pro chamber, but would they take away from the sound?

Cats always take away from the sound

So should I just keep them off until emissions, and then put them on?

I would. Might as well enjoy the sound as long as possible. Lol

Hell yeah man, I definitely would like you to post a video of it when it's finished. But from a previous forum I was on, the catted prochamber hardly sounded different than the stock catted H and a lot of people weren't very happy with the quietness of it with the cats. I definitely would suggest getting the o/r version.

Is there a way if I bought 2 pro chambers, to have one with a cat and one without and simply swap the 2 when I go for emissions? I'd hate to weld cats onto the long tubes. Could I have an exhaust shop cut part of the pro chamber and weld it onto that instead?

Yes this could be done. An exhaust shop can pretty much do anything for you. And you don't weld cats onto the longtubes. They go on the midpipe which for you would be the pro chamber

A cool way I've seen it done is have the cats cutout and have a straight through pipe made up with clamps. Than you can just unclamp the straight pipe and clamp the pipe with the cat back on. Unless your like me and hate having "clamp on" exhaust... It does work tho if you need them for emissions.

Ya clamp on exhaust just isn't the same as a nice clean welded exhaust IMO.

That's good. I'll just buy another pro chamber down the road and put cars on that one to swap out.
