Pt. 1 Thrush Welded vs. Flowmaster 40's - 1977 Ford F-150

Hey guys, I finally was able to finish the entire exhaust system after adding my BBK shorty headers. Today's vid shows how I completed the rest of my exhaust system all the back with 2.5". It started with adding the header "down-pipes" then connected to a mid-pipe then the exhaust mufflers then route to your destination. Baloo here has them dump after the muffler with angled tips to come later.


**For all the F-100/F-150 from 1973-78 look very careful at this video. If you are having a hard time trying to find headers (watch last video) and need to know about clearance and if things will fit. Well, I will say following this route that I took with the parts below will let the beast come out of your trucks.**


Sound comparing/performance to the Flowmaster 40's is almost equal if not better in my opinion. I have always been sold on Flow's. Well, now that I have seen what Thrush "Welded" mufflers offer I may be switching over from here going forward on all my builds. Plus, have the price so your also saving cash to add to your build for other things.

Down-pipe's - From Summit $20 part# 41726
Mid-pipe - 2.5" Whole "stick" $40 from muffler shop, cut in half to 48" each
Thrush Welded Exhaust - 2.5" inlet/outlet 2 chamber - "Sounds AMAZING" $50 Each
3" bolts/nut Hardware - $10
Exhaust Clamp/Hangers - $40



Not an expensive build, plus doing it yourself is even better. Hope yall enjoy and this helps your build.
