    Cts V exhaust question

    First off, I did do some research and tried to find out any info I could but I was hoping for some input from the wealth of knowledge that is this forum. I have a two part question:

    1. I am considering installing some Pacesetter headers (can't beat the price) on my V. I would also like to keep the rest of the exhaust (including the cats) stock except for muffler delete. So in essence it would be Pacesetter headers and muffler delete. Has anyone gone this route and can you tell me how it sounds? Also is there an issue with keeping my cats with the pacesetter long tube headers?

    2. I live in California.


    Thoughts?

    Although some long tube headers offer catted pipes (w/high-flow cats) I don't think any long tube headers work with the OEM cats. You could, in theory, move the cats downstream of the headers, but because of their size, shape, and weight the OEM cats do not lend themselves to that kind of configuration.

    Re: Cts V exhaust question

    I looked at doing the exact same thing. There is no way to really use those factory cats if you go with any of the longtube options. You would have to get aftermarket high flows like mangnaflow or thunderbolt welded in downstream. I am looking at bypassing the headers and leaving factory manifolds and cutting out the factory cats and welding in a pipe and doing the before mentioned cats in the midpipe section of the exhaust. It is kind of like a 50/50 setup. Just need to stop replacing maintenace parts on both of the cars for a bit to free up the cash.

    A lot of folks have gone OBX headers. They are more expensive than the Pacesetters, but are less than the higher grade headers (Kooks, etc.), are available with high-flow cats, and are stainless steel.

    Well crap. I have a feeling I may be opening a can of worms ESPECIALLY being that I live in California and will need to smog this car in about 8 months.

    I saw somewhere that the pacesetters have smaller primaries and smaller collectors than the B&Bs. search carefully.

    When it comes to driving the V around with all my windows down and sunroof open in 75* weather in January, not so much. Haha

    Thank you. I'm starting to get the idea that going the cheap route with pacesetters may not be in the books for me. :-/

    Pacesetters have 1 3/4 primaries and 3" collectors. If memory serves, the OBX have 1 3/4 primaries and 2 1/2 collectors.

    Pacesetter with off road connections will bolt to the stock exhaust, eliminateing the cats. That is their benefit, others require cutting the stock exhaust (from what I could tell). They are 1-3/4 primaries and 2.5" collectors. The obx is 1-7/8 primary and 2.5" collector, the kooks are 1-3/4 or 1-7/8 primary (optional) and 3" collector, B&B I assume is 1-7/8 and 3". I'm not positive on the b&b but I believe the rest are correct. Unless you go with a 3" b&b exhaust, all other exhaust is 2.5". The larger primaries are worth some power, see this link:

    For sound clips go to ls1tech ctsv, there is a thread stickied with all sorts of combos.

    Re: Cts V exhaust question

    Sorry to be a negative nancy here, but it seems to be a waste to put headers on only to bolt OEM cats on, too (assuming you'd be doing that). There'd be little if any performance gains and no improvement in sound.

    I'd recommend you move and leave that desiccated over-populated State.
