I am looking at buying a RB true dual header as my first exhaust upgrade. I am just curious if this will bolt up to the stock exhaust system or will i need other parts?

 

You would have to make a custom Y pipe to connect it to the stock cat back. It's going to sound like a pissed off beehive inside a tin can.

you'll need their midpipe too unless you want a exhaust shop to mate it to your cat. if you do that they'll probably chop and ruin the header.

then if you get the midpipe the diameter will be larger than your stock catback so you will have an exhaust leak.

 

The racing beat true dual system is 2 pipes all the way back, it never meets to one pipe so in order for you to have the headers it means you would have to have the dual pre-silencer OR you would have to get a custom made cat with two pipes hanging out of the front of it, like some genetically mutated monster cat or something.

 

Just get the racing beat collected street header. It would make no sense to get the true dual header unless ur getting the full true dual exhaust. And jw, but why aftermarket header with stock mid pipe/cat and catback?

Great condition RB 13B Road Race dual exhaust header. This has been sand blasted and is ready to go. You have two choices for exhaust setups if you buy this header. It's currently connected at the end and merged for 2-1/2" straight pipe use past the header, or you can unbolt that piece and use it for true dual. Looks great and ready to go! Asking price is $225 shipped.

 

thanks for all the info guys i was looking to slowly piece together an exhaust. Looks like i may just go the rb collected header and corksport cat back route

 

Shadow, I dropped my price to $180 shipped and my header would work great for dual or converted to single at the end. The price is great and the headers are too. Let me know if youre interested.
