new cat + Vband clamps + resonator = $300
So my cat is a bit cloggy:
https://www.miataturbo.net/forum/showthread.php?t=26736
I talked to the guy who built my custom exhaust 8 years ago, and asked a quote for:
- cut out old cat which is welded in
- new Carsound metal cat
- add Vband flanges to new cat
- add flanges to car
- install above Vbanded cat
and in addition:
- new 12" Maremont resonator
- add flanges to resonator
This way I have a removable cat, and I can swap in a 12" resonator for track days (I want it quiet on the drive to and from the track LOL)
Vbands will make swapping easier.
Cat is $110 .. resonator+ all vbands + labor = $190.
Thoughts? BTW I have zero welding skills.... (M@! When you gonna move back to the bay area??!! )

Turns out he didn't understand v-band. He quoted for regular flanges.
Vband clamps are pricier.
Looks like his price will drop $50 (to $250) if one side will be a slip joint + U clamp.
You can't have both sides = slip joint because it will be physicall impossible to insert the cat wihtout moving the rear section of the entire exhaust back by >3 inches.
I need to look under the car now and think about how it'll look. espeically with the butterfly.
Can I have a pic of y8s slipjoint + band clamp?

I added a resonator to my setup.
Had two u-clamps on each end, slip joint on both sides. Eventually I swapped one of the clamps out for a band clamp, but it started raining while i was working and never finished the front one.
fast forward a few months....hit a manhole cover that was sticking up too far due to the pavement being scraped out for repaving...I dodged a few but didn't see this one. Ripped the u-clamp off and bent my 90* pipe into the muffler.
When I pulled the exhaust down to fix, I removed the band clamp. I had used this permatex exhaust wrap/gasket stuff under the clamp. It held strong through the impact. In fact it was almost like I epoxied the two pipes together (reading the description on the link, looks like it's supposed to do that. We ended up bending the 90* back with a ton pressure on that joint (stuck the far end under a car and pushed down on it). The seal never broke, instead of grinding and welded this seam as I did for the other side, I put the band clamp back.

$7 each off a seller on ebay.
might as well get the flanges welded. As cool as v-bands are I don't see the need for them. Typical 2-bolt flanges don't bother me.
You shouldn't take advice from me. I currently own a beat up $780 catback.

So muffler guy looked at my exhaust.
He says I can use either a skinny glasspack resonator with louvers inside, or some Ansa non-louvered resonator that's thicker in the middle. A Magnaflow or Dynomax won't fit.
He says the louvered glasspack will be quieter, but I have my doubts given how skinny it is.
Has anyone tried Ansa resonators?
