I put some vibrant 3" resonators on after my bullets. The papers that came with them say to put them soon after the headers for best results. Vibrant has some nice stuff.

Texas Speed will do under the axle I think, their longtubes will go with it just fine.

I'm wondering if there's a kit that goes over the axle. I don't want to destroy my ground clearance since I want to lower 1.25"ish later.

Kooks makes one and Bassani used to.

I have a question. I just received my tsp rumbler true duals, but I didn't get any cats (I know stock ones are complete crap), can anyone recommend me some good high flowing cats to attach to the system? I eventually want to get headers but don't have enough yet, also will cats attach to headers and a true dual system, unfortunately Arizona requires emissions testing...

Once you get headers your probably gonna have to get them welded onto the exhaust.

To everyone who has true duals and headers, do they just connect to the catalytic converters? Because I just got my tsp true duals and want to get headers but I have to have cats to pass emissions.

The rumbler system you purchased is not going to pass..... It was designed to connect to long tube headders and be dumped before the rear axle. If your running your stock cats/manifolds, you will need an exhaust shop to weld up intermediate pipes to connect the thing. If you want cats, I suggest picking up a set of spun cats from summit (about $100 a piece) and have the exhaust shop weld them in for you also.

-not to be a dick or taken ill, but you should have done more research before purchasing anything.

Alright thanks, yeah I did but I couldn't find anything about it all i found was everyone set it up with headers So I assumed everyone just waited for the headers to do the install instead of doing 2 installs.

Apparently they will pass as long as there are cats welded in from what the muffler shops are saying because I called them and they said there is no visual testing here all they do is plug it into the computer or whatever.

My ss is lowered on agx's and eibach prokit. I'd really really like to run tsp's true dual system instead of my current catback setup. How bad is the ground clearance going to be?

Looks really good, except the x pipe.

I'm going after that exact setup but with some cutouts.

The x-pipe is actually one of the nicest parts on the exhaust. My buddy did an awesome job also of polishing the heat out of all of the welds to make it look like one piece of pipe. Im sorry for all of the crappy phone pictures but I dont own a camera.

I guess I fail to see the trashing of the X Pipe. I think that exhaust looks incredible, better than the Kooks true duals. It definitely looks as if it has better fitment than the Kooks.

My thoughts exactly. That is one of the slickest exhaust I have ever seen. I would have used a muffler similar to the ones on the slp pro flo setup but thats just me.

That sounds like an amazing combo both aesthetically and sound wise.
