    M20 Custom 2.5" Exhaust Build

    My old exhaust was a rusty pile when I got it. I finally got sick of it and decided to make my own to replace it
    - aluminized steel
    - 2.5" single so I can go turbo later (I know everyone says 3" but I don't care, I don't want a 3" exhaust)
    - made my own 2 into 1 collector cause I'm cheap
    - 50 series Flowmaster (delta flow) cause it's "quieter"
    - Summit cat
    - All tig welded cause I'm still practicing on my new syncrowave and need to start doing less aluminum

    Pics:

    The muffler fell off when I pulled it apart


    Jigged up the flanges before I cut the crappy welded o2 sensor off so I didn't have to test fit on the car, all on the bench instead


    Mocking up the scraps


    Cut, trim, weld. This actually turned out pretty good.


    Down pipe all done


    Fitup of the front half


    Split the halves with a v band flange


    Stainless welds nice


    Two halves complete


    Made some tips with leftover scrap. Had to mig weld since I rand outa argon at 3am


    Tips fitup well




    I spent a long time fitting this thing up nice a tight to the body all the way back cause I always hit stuff around town. There is a finger thickness gap at the tightest spots and the fitup is great. I reused all the factory mounting points and brackets. Sure enough on the way to work I ran over a dead animal and there were guts all over the bottom of my car but the exhaust was OK.

    Sound is great.8)

                Very nice! I'm going to do an M50 swap soon and need to get an exhaust installed and I might try something like this.
