Pic from last night but I’m gonna end up going with this and if it’s too loud or quiet change it I’m gonna clamp it on and put a aftermarket 3” tailpipe so I can have a exhaust tip

I have one of these (single in, dual out) and it's a tad loud for me but not horrible. I'm 43 now and long gone are my 19 year old LS1 with headers/no cats/true duals. Went with it due to reports of no drone and can confirm. I may just get the larger 300 series and see.


Edit: Video of start/idle:

A lot of folks run with those. Seem to be really popular. With it clamped in place, you could always get something else and sell off the Thrush on Craigslist, Ebay or Marketplace, if it is not right for you.

That’s why I wanted to clamp it eventually I wanted to weld it if it’ll weld I was gonna give the noise level a test spin and if it’s suitable and the wee woos don’t go off on me I’m gonna stick with it

If I ran straight pipes and the inspector for the RMV happened to see a missing cat, I'd fail and probably get a fine.
1. Open and hollow out a catalytic converter, or find one already hollowed out.
2. Stick straight pipe through hollowed catalytic converter body.
3. Close catalytic converter body around straight pipe.
4. No fail, no fine, Bob's your uncle.

Standard disclaimers apply - but it's a typical ploy that often works if the tuning is right.

I'm shocked that can be done in CA... Especially, since they were the ones that started the toughest emissions requirements before anyone else.

I am in MA. We don't need to do emissions, but still not legal to remove federal emissions components (cats).

But, no worries. I may be a bit jealous, but I am not a rat! - Enjoy!
All depends on who you know ;) plus you can always run some pipe through your stock cats or get a set of “dummy” cats just for looks. As long as they don’t break out the sniffer you’re good lol. Find you a mom and pop shop out in the sticks somewhere to get your inspection done.

State system priced a lot of mom & pop's out of business.
The ones who are left are scared rabbits... They had to buy multi-cam video systems that live feed to inspectors. I have heard they have jumped into the shop system by chat and asked for specific things to be re-checked, if it seemed like the shop might have "missed" something.

I wouldn't do anything that could get me in trouble anyway. I am more than happy with the Corsa performance cat-back just the way it is now. Love the sound!

I've run a lot of mufflers. Most of them on the market. For the price, and level of noise I like any more (not a lot, just enough) I really like the FlowMaster FlowFX series.
