Time to update this thread…Houston, we have a problem…yep, the weld on the muffler cracked.
the problem showed up about a year ago. It would show up when you first started the engine cold, it would go away after a few minutes, my guess, when the exhaust warmed up and expanded. I looked several times but never saw the issue until yesterday.
anyway, it’s time to contact the company I purchased from and @Magnaflow
I will report back on the Magnaflow Lifetime Warranty service on this Cat back exhaust system.
I am very optimistic they will take care of the issue since it’s such an obvious defect.
BTW, I have the same system on my 2000 Firebird TransAm, no issues, installed at the same time as the SC430.

Magnaflow factory…impressive

Wow, I never would have guessed that would be a problem for a Florida car. It's like it wasn't factory rust coated properly.

I am not really sure it was a rust through situation…this is their stainless steel exhaust system with a limited lifetime warranty…but I could be wrong
here is a pic of the pipe welds when new.

Update…I called Magnaflow this morning and they told me I should be okay with a warranty claim but needed to work with the Authorized dealer I purchased from…so I called Hottexhaust up in Canada and Chris was like, no problem, give me your order number from 2018 and send me a picture of the cracked weld and he would submit the claim with Magnaflow. He said they would either replace the muffler or replace the entire system…more to follow, but I am still optimistic about this process.
it will cost me labor money but I am okay with that because I understood the Limited Lifetime going into this project

If they give you a new one, I suggest you spray some high heat paint around the soldering area to help prevent rust in the future.

No rust installed back in 2017

Magnaflow supported their warranty and sent me a replacement muffler…I decided to change it myself since I have retirement time on my hands ;-)
it was my first attempt at an exhaust and must admit, I wish I had a lift…I may pick up a lift like Oneround has…I forgot the brand but I think it lifts the car 24+ inches.
i measured my ramps and Jack stands, it was 14 inches…

Here is what it sounds like with nothing behind the third Cat… :-)

QuickJack. I got the 5K pound version. Bought it through Home Depot when they had it on sale just before the company came out with new model names (don't know what changed beside the name).

The "regular" version 5K lbs unit I have is barely long enough to meet up with the SC430s pinch weld spots for lifting, but it handles an Avalon and a Mazda MX-5 with no issues. Didn't measure, but thought the extended version might have issues fitting between the front/rear tires on the MX-5 and SC. On their website regarding new models they now have a page that address size between tires and which model to get.

Sound really nice,. Hm, maybe I should just straight pipe after the crushed portion of the exhaust. Save some weight along the process as well.

Goodness that red SC is bloody gorgeous. You have her polished like a jewel.

I like the sound too. A subtle but meaningful purr.

Okay, it’s all finished and she is good to go again…not stock quiet but just right…at least my wife and I think so.

Costco also carries Quick Jack and occasionally places them on sale. (Maybe keep a look out for them on Father's day?)
