go turbo. easy then.

If you are thinking about the Aero for a 8v71 N/A engine forget it ,if you do, buy good ear plugs

I did that about a year and a half ago. I was initially concerned that it seemed very loud but adapted to it quickly. You don't really notice it when you are up to speed, but those around you might.

I remember there was a suggestion to put maybe a 7/16th bolt across the tail pipe to break up the sound. I have to try that but keep forgetting.

Our NA 671's dual exhaust is 3" start to finish x two. Probably just over 200HP & totally dependable. No hurry, ever...

Dan, does your dual 3" have mufflers or is it straight-piped...?

It has two Stemco mufflers. Not loud but sounds sweet.

We put an aero on our 500hp 8v92TA and I love the sound but it is definitely loud. Wouldn't mind making it quieter but I have zero room now that I have a huge trans cooler where the muffler used to reside. Oh well.

When you get tired of the noise, Donaldson makes a 5" oval with inlet and outlet on the same side for turbo engines. Check out Donaldson muffler M120131. I used it on my 8V-71 turbo and now have it on my 3406B I liked it so much. Good Luck, TomC
