Exhaust system recomendations

72 Blazer 4x4 cst stock 350 engine with stock ramhorn manifolds. What do you guys recomend I have installed? I am thinking 2.5" pipe dual exhaust exit just behind the rear tires. Not sure on the mufflers? Should I take it to Midas or a mom&pop shop?

Re: Exhaust system recomendations

If the Blazer is driven without a top, you may want to consider having a downturn on the ends as that may help prevent exhaust getting sucked into the back.

This is true. Out the sides is the best method to prevent that.

One thing to consider is adding the 4wd exhaust brackets to the opposite side when you do the new exhaust system - I did this in my K20...but I'm really a^a!

Re: Exhaust system recomendations

From GM our K5's were all single exhaust and the 4wd's have an exhaust bracket that attaches to the frame rail as shown here: http://67-72chevytrucks.com/vboard/s...d.php?t=567957

I made use of another 4wd hanger bracket to make the dual exhaust setup appear to be "stock". The opposite frame rail already already has the holes to bolt the second hanger right up. You can see the opposing brackets attached to my K20 frame below - they're anterior to the rear cab support.
