exhaust question

[axemurdock]

I have an 86 non turbo 6.2 with duel exhaust. I'd like to know can I cut off the big bus looking mufflers and run 2 straight pipes. Would that open up the flow and give more power ?Does this motor need back pressure to perform? Its a m1008 military chevy so its got the gov tweeks to it.

should help but will fairly loud. Turboed engines are much quiter and can handle being straight piped.

If ya want to keep the noise down and still have good power. Go with some Flow masters.

The 6.2 will rap real hard and loud with straight pipes.

The Flow masters used on a larger cube mouse motor will sound real nice on your little diesel.

In fact, other than the rattle under the hood, the exhaust note is very similar to a small block.

Adding some larger pipes and the flow masters will really help things. 2-1/2 pipes from the engine to the mufflers and maybe 3 inch out the back.

This will give you about all that the little 6.2 can breathe anyway, plus sound nice and not drone in the cab.


As mentioned, a turbo engine is a lot quieter even with a straight pipe than an NA engine.

The exhaust note gets muffled a lot after traveling through the turbine wheel.

Have fun and keep us posted.

OH BTW, resist the urge to use glass packs, they really sound horrible on the 6.2

My Burb has somekind of aftermarket SS 3 inch. Has a nice rumble to it.
