I'm hoping to get a pair of SLPs, but I already have a problem. The one's I might get from someone are for dual converter cars. My question is, how would I get a good after cat system put in if I don't wanna put cats on? Would I be able to get a shop to weld on another pipe to join the two? Would that be bad? Another thing I was thinkin was to go and get two small mufflers, and attach them after the Ypipe, then add a turn down pipe or something. I'd just like some advice, for I need to decide if I would have any use for dual cat headers, since I'm getting an awesome deal on them. Thanks guys.

most reputable muffler shops wont let u get away with just ONE cat when you NEED two, but then again they might, why not just run true dual exhaust??

True duals was something I really wanted to do a while back, but I decided not to sacrifice any ground clearance. As far as a shop not doin any work, would I be able to do anything? Something like the previously mentioned stuff: puttin on two mufflers right off the Ypipe, then gettin some turndown pipes. Wouldn't that work? Thanks again.

Most shops around here won't work on a car that doesn't have the proper number of cats equipped.
It's a violation of federal law... i.e. it's a felony finable up to 100,000 or so.

The headers are the same whether you have a dual-cat or single-cat exhaust. Its just the y-pipe that is different. You can have them make up a new y-pipe or adapt the dual one into a single setup.

You could also order the single cat y-pipe, install your headers, and drive over to the exhaust shop to have the rest of the exhaust put on. You might be able to get away with that.

 

I probably won't bother gettin a new Ypipe, or converting the dual into a single. I think the easiest thing would be would to just get two mufflers and put them at the end of the Ypipe. But, since I have hardly any knowledge pertaining to exhaust, I need to know if that will do the trick. I would just like some info on whether or not it will work, and If I'd be holding back any power. Thanks again,

There's not enough room under there to put a muffler right after the y-pipe. It'll drag on the ground.
