ladies and gents help asap
ok guys need some help I live in cali, have a 98 ss ls1 m6. Heres the issue the weld the connects the header to the cat has broke and it's making a nice but off noise. It needs to pass smog next month cats barly passed 2 yrs ago so those a probably bad anyways. So heres where I need some advice, I was thinking of the slp high flow cat(if there are any better let me know please i'm very happy with my loudmouth exhaust, could be deeper but i like it.) The idea is to put the high flows on (will this pass smog.) then I want to add some headers and a y pipe. I had a cut out wasn't electronic got a ticket so had to fix, so also thinking about getting a cut out maybe 2 and electronic this time so I can close it when cops are around. so what kinda headers, high flow, and y pipe and where to put the cut out/ outs.

there are many different kindas of headers. I would recommend the Kooks 1 3-4 stepped to 1 7/8 coated, but they are a little pricey, about 900 for the header 200+ to get them coated. Pacesetter makes a good header for the price, coated about 350-400.
Cats are a pain in the ass, SLP high flow seem ok, I run the magna flow high flows. Not sure if SLP has the metalic spun filter, but would go with those rather then traditional ceramic core ones.
Y pipes are pretty much universal (kinda). best off is to get one that is made for your headers. Or in the case of the pacesetters you can also use the TSP one.
Cutout placement- Depends on how low your car is. If if is dropped I wouldn't recommend putting it on or near the Y pipe. rather put it on the I pipe before it goes over the axle. Most clearance then esp. if running elec one.

Broham is correct. Long tube headers aren't legal in California,,,even with cats....I know it sounds strange, even if it were to pass the sniffer test,,,,California does not allow the cats to be moved further down stream from their stock location.
Other states are soft on this, but California is sticky here.
Coated long tube headers stand out like a sore thumb when the hood is open. I prefer the painted headers myself,,,just been around the coated so long and learned a few things I didn't care for.....with that said I paint them black,,,they hide quite well that way and don't jump out at you as the first thing you see... But of course they make dark color coatings as well so they don't pop out so much if it's coatings that you prefer...

If I read you right, then you don't mind switching back and forth between the stock setup and some longtubes so you can smog the car.
If it were me thats what I would do, just to get the car smogged, flash in the stock tune and go. Once done switch back to your long tubes and such, flash in the custom tune and be done with it.
Only every couple of years anyway, not so bad to do I guess. Probably switch it all in a weekend..

Jet Hot makes coatings that are dark in color and won't really stand out to much, also if you know a place that does powder coating, ask if they have the high temp stuff. I got my pacesetters powder coated with some stuff that is supposed to be good up to like 1700 degrees.. Holds up great against the heat.. The tops and most of the primaries still look like the day i put them in. The water has taken toll on the collectors though..
Another option besides shorty headers are the Mac mids. If you take the time and clean up the welds and what not I hear the flow pretty damn good. Had them on my car for about a yr and a half they were pretty good. And you can probably get close enough to stock location of Cats with them
