1970 mustang 351 cleveland Flowmaster super 40's before and after 

351 C music to my ears .... they are great engine, I’ve got a 79 Ranger XLT with a 351 Cleveland, in Australia 🇦🇺 we’ve had Cleveland in our fords in the 70’s

Hands down, the flowmasters were an improvement. They sound fantastic on this car.

flowmaster is the REAL muscle car sound

Clevelands live for WOT and things can really get loud. Unfortunately granny never did power up for a good comparison.

I hear the clutch rod sweak. I miss that sound lolol

thanks for the comment! The video sound quality is never like real life but the tone went from a kinda choppy old exhaust that sounded like garbage inside the cab to a much nicer deep tone. There weren't really any noticeable HP changes until the double pumper was put on haha

Those 40s sound amazing.

I'm sure. I think cheapies sound more like the engine than the Flowmasters. We've used both on our truck and the cheapies sound better to me at least.

great comparison!

a whole new world of difference, try single exhaust tip, louder

Sounds way better!

Nice! H pipe x pipe or straight? Stock engine?

Sounds great

yea buddy!

aww thats to bad to hear about the mach 1 but this mustang has been sold haha
