So I picked up a 2.5 inch Tsudo n1 cat back off of a supercharged cobalt for a real good deal. The problem I feel I may encounter is that the stock flange seems way to small to bolt up to the big 2.5 Tsudo exhaust. So do you guys think I should just hunt for a new flange to weld on or do you think it should just bolt up to stock.

On a side note I'm not sure if the 2.5 exhaust will be too big. I do plan on super charging it this summer so it will just be temporary if all goes as planned. Any help is greatly appreciated.

Thanks a lot!

It will be fine. The stock DP is smaller, but put a new gasket in and you should be fine

Wow, super speedy reply! Haha thanks for the input but are you sure? I hate to question your advice but it looks so small compared to the big beefy 2.5 flange!

Yeah. I ran a GMPP catback with a stock L61 DP on Phoenix a looooooong time ago. It will seal and work.

Thanks so much man, I really appreciate it and am super thankful I won't need to do any welding��

Just an update, but it was like a weird welded/fused bolt that was connecting the 2 pipes together so I'm going to a buddies shop and just getting him to weld on a flange. Thanks for your help though!
