I just installed these cat delete pipes the other day and cold startups at 7 AM is a huge problem for me. I have an x pipe. What was your fix for this? Did you change your exhaust at all?I got mine installed few days ago with a H-pipe but cold starts at 7am it makes me feel embarrassed thinking about neighbors, what's your mid pipe? You got any resonators?

what mufflers do you have? You may need to add a middle resonator to get it down to tolerable levels without cats. It makes it so much louder when they are removed

If I get the cat delete pipes, do you think adding these valved mufflers would help with cold starts? https://valvetronic.com/products/universal-valved-exhaust-kit?variant=39496535113764

Its a nice kit for the cost. I spliced cats into mine which was a bit tedious. The fun part is welding the flange onto the header. You should really take it off to do it right. The outlet is oval. By alot. we heated it and beat it with a hammer round to fit the flange. We took turns wacking at it as even with heat it moves sloooow!
You could tack the flange on the car but at the very least, disconnect the battery lest you blow up a module. All of those modules are chassis ground so even disconnecting the battery has its risks. I marked it. Tacked it out of the car and then checked the fit, tweeked it a bit. I also cut the straight section on the drivers side much like the oem pipe. I welded a coupler to the front half, cut a slit in the coupler and then clamped the back s shaped into the front pipe. That lets you fine adjust things a bit.

I got my 2M kit new off facebook marketplace, is there supposed to be 1 or 2 flanges to weld on? I only have 1 which confuses me because once you cut the driver side cat off, won't you need to weld 1 flange onto the header side and 1 flange onto the cat in order to bolt them back up?
Also do you know the purpose of the 1 gasket that was included?

How long did it take to receive your kits? I just ordered mine 2 weeks ago. Hopefully no issues with the reducers/clamps like I've been seeing...

Please keep the thread updated on your experience. I thought of ordering a kit myself, but their FAQ states the following:
And with their f*u attitude I'm hesitant to order from them.

I actually didn't even want to order from them myself, as I see they more than likely just get their stuff from Aliexpress but they're the only entity online that sells cat delete pipes at that price range. I couldn't even find their supplier on Alibaba either to order directly from them, so I imagine they may have negotiated with one of the Chinese companies and sent over specifications to have pipe bent and welded. Lethal performance doesn't offer cat deletes anymore and MAK wants $700 so I settled on paying the $350 they wanted. I considered having a muffler shop just chop the cats off but I really didn't want to have my stock headers cut up unnecessarily. Time will tell if it was a good decision or not. I hope everything comes correctly in the kit, otherwise I'll probably have to contact my credit card company...

If you can get passed the attitude, the kit is pretty decent. I fabricated cats into mine.
