Exhaust suggestions 75 Blazer 350 4 Barrell carb
The manifold is good. The exhaust is rusting out pretty bad. Need to replace the system and would like to get something good and deep sounding. Suggestions would be appreciated. I've only had experience with Flow master exhaust. But am open minded.

Look into Borla exhaust.

Re: Exhaust suggestions 75 Blazer 350 4 Barrell carb
I like Magnaflow and Borla. Especially Borla. I don't like Flowmaster - they sound hollow/ringy to me. I also like boxers. It's a subjective thing.
Take a listen on YouTube - TONS of people post up vids of their trucks running with hordes of mufflers. Find one you like, and copy it.

Re: Exhaust suggestions 75 Blazer 350 4 Barrell carb
ny truck is a pickup and an 82 I had to go with a cat so I put in a new crossover pipe to a ingle cat then ran that too a magnaflow and duals out the side basically a stock exhaust with a magnaflow It was the lowest sounding magnaflow and doesn't sound much different than a stock gm exhaust

Re: Exhaust suggestions 75 Blazer 350 4 Barrell carb
So I liked what I heard with the Bolra and Magnaflow. Magnaflow doesn't offer anything for 1975 chevy trucks on their website. I'm further investigating Borla. Do the different models from the same manufacturer typically sound similar. It's difficult to find vidoes on Borla especially their different models.

Re: Exhaust suggestions 75 Blazer 350 4 Barrell carb
They will have a "generic" or "universal" fit that will work just fine.
