That OEM system you are installing is going to be the bees' knees. If I had the coin and mine were a little crappier I would do the same. That's money well spent.

Nice find on the Hottexhaust.com Magnaflow 20% off sale. Ordered new y-pipe/cats today. We are now required to be CARB compliant here in Colorado, so still not cheap, but the sale certainly helps. Trying to decide on the remainder of the exhaust (muffler/mid-pipe, and tailpipe/resonator). As mentioned since Borla cat-back in now more than Toyota OEM, I'm kind of leaning toward OEM. Anyone have any other good suggestions other alternatives for good quality mid and tail sections, or find any good sale deals online for OEM.
My shopping experience with hottexhaust was good. Lots of updates, shipped quickly. They really need to package these things a little bit better; both of my mount flanges were poking through the box when I got it. Everything looks fine, but still.
Installed! Can’t tell a lick a difference. Just shinier.
283K faithful miles of running, thanks (for sale)
Hoping for the same level of good service by Toyota

Looking good @COYS I feel like you're the only recent replacer of cats that hasn't felt a difference. Maybe yours were not that bad?
More "pull" mentioned in a handful of posts.
Damn that looks nice. Wish I could do exactly that for the 94.
I'll be putting some miles on it as I'm actually headed your way next week. More pull or not
no oddball issues from my constant fettling. I'll also keep an eye on mpg if it helped any. Thanks!
For those who replaced their original exhaust system with 100% new T parts from either manifold to tip or y pipe cat to tip, what if any changes did you notice sound wise and “performance” wise?
I’m asking because I have no frame of reference other than my own. Happy to compare notes. Many thanks.

They wouldn't match the online sale prices?
Mine was always library quiet at idle.
What about when accelerating with throttle? Mine sounds a bit boomier.
Also can you pls take a photo of the middle exhaust hanger? Mine looks a little twisted.

Thanks f
Mine looks like this. Wondering if normal? Not sure if any adjustments can be made if not. Gracias!

He told me "no" when I asked a month or two ago. Wish he would.
After having driven about ~250-300 miles with the full system on, I do notice a couple of things now:
- Exhaust has a different tone to it - hard to describe, but it's got a bit of light bass to it under mid throttle acceleration with windows down at slower speeds
- I am noticing a .75-1mpg improvement (~12.5 to 13.5) around town + hwy driving with AC on
@COYS An idea regarding the hanger pictured above, that's under some tension and leaning to one side. There may be enough slack/slop in the holes that the mounting bolts on each end of the rubber isolator pass through for you to loosen the nuts a turn or two and see if it settles in with a little less binding. I don't recall if there was much or any slack in these from when I replaced all of the rubber on my stock exhaust system but it's possible.
It's also possible that there is adjustment/slack in a different one of these hangers, or other joints, etc. and that when the system was installed the isolator under tension (in photo) was tightened down early in the assembly process and then when other items were tightened they shifted things around causing the tension you see. I'd think you'd want to loosely install the entire new exhaust / hardware / etc. then massage it's alignment and tighten things down in a way that minimizes side-loads on the hangers etc. A mech working on someone elses rig may have been in more of a hurry and put less effort into dialing in the alignment, etc. or the tension could be inevitable and just the result of how it all fit together.
I doubt that I'd break any seals joints in the exhaust but I may tinker with loosening the hangers/isolators a bit and seeing if things relaxed a little. If you break any sealed joints to try to relax the hanger tension you'll probably want to install new seals even though the system is so new, etc.
Not sure it's worth doing anything just thought I'd share ideas on your question in case it's bugging you. I also vicariously enjoy the level of detail you take things too as I can't justify it with my rig but would love to be able to do the same
