Y pipe Mod

[ScLeCo]

The receipt says "Magnaflow Muffler 14148".

Good luck and I'm sure you'll enjoy them as much as I do.

I found them thanks. I need the 14149 which are the 3" pipe.

You'll know it's running with them SCLeCo,especially with a blower on a big cube motor,lol. I ran them the first time around,but i like to get along with my neighbours as i've been in the same house for 20+ years,so i only ran them for maybe a month,lol

Sorry to resurect an old thread but I have a different question about the Y pipe.
On my '23 I have the Chirp noise on startup that gets a bit quieter after it warms up (and the RPMs drop). A lot of people have said they traced it to the stock Y pipe. Has anyone noticed the "chirp" going away after replacing the Y? I could care less about power I just want my truck not to sound like garbage.
