i'm just trying to make the point that i wouldn't let ca smog testing prevent me from putting on a good exhaust.
I hear you. Assuming you are local to the Bay Area, Maybe one of these days, I can get a listen at what you have set up. What do you have, and how do you like it? Does it drone at speed? Any regrets or nits about what you have ?

A decent flowing exhaust is the foundation for every mod and should be on the top of the list of initial improvements you make to your car. The stock setup is crippling.
On the occasions when I put it back on to smog it's like 80% of the gains I've made from ALL my mods are gone. Stock exhaust is just not compatible with performance.
Thanks for the generous offer. What exhaust are you running? I would love to get a listen to it, so I have an idea if it will drone/annoy me on the freeway or not . I still have my eight jack stands and one jack laying around, so I probably should have looked into how easy hard it would be (I did a lot of wrenching when I had my 1993 Nissan 300ZXTT, but after kids and since the 996TT, I haven't seen the underside of a car for a while.)

Well, you're asking the right person. I've tried a fully open 3" x-pipe (EB-Werks), couldn't handle the drone but it was a great sounding exhaust at WOT. Then I bought a speedtech 3.0 which is also a 3" x-pipe but has a muffler surrounding the x-section and this eliminated most of the undesirable noise generated by the previous choice.
Finally, I bought a quieter muffler section from speedtech which is interchangeable with the rest of their system and this proved to be just right for me.
I'm in Dublin and you can hear it whenever you like, just PM me.

sorry i can't help. I'm currently in northern tijiuana but i would take mrmaas up on his offer on that speed tech if i were you. as far as the 200cel kline i have? it is mellifluous at all ranges and without any drone. purrs at idle, a joy to behold and its CHEAP ( relatively lol ). it's gotta be right there with the speedtech though i haven't heard them in person.

best exhaust ive had since my old cargraphic, and thats saying something

Andy, my Europipe stage 1 exhaust has no drone and is pretty mild mannered. Makes the car sound more exotic without being too loud and gives you good performance gains. The europipe has no problem passing smog and passes the eye test to the untrained eye since it isn't too flashy but is extremely well made. I'm in the bay area as well (San Jose). if you want to hear what mine sounds like let me know.

Do you have any 60-100 mph or 60-130 mph times etc. I would be fascinated to see them on your build

If you are into track days and canyon roads, I'd put a good bit of that budget towards handling mods. You will enjoy the car much more. Coilovers and sway bars make a huge difference. Then just tune exhaust for power, honestly the most you really need power wise after that is K24 or small hybrid.

For those two things the supporting/residual mods and service will add up. Track/street brake pads, fluid, maybe some brake ducts, better alignment, maybe some good tires. And on the power side, DV's, a clutch at some point.

Make sure you don't forget all of the other mods that will eventually be needed for your driving style.

Thanks for the suggestions. I am planning on doing the coil overs. Currently holding on the engine mounts and sway bars for handling for now.

Hesitating about exhaust and intake because of the stricter smog visual checks in California but will get software tuning for more power. And doing the DVs.
