hi

is any one making a 3" exhaust system for 68/69 valiants 2 door with 340 with stock 69 340 ex manifolds ?

i want 3" mandral bent pipe with 3" head pipes .

thank you !

Headerback systems yes.But you wont find something in a box that fits from the manifolds to the headerback systems.,Im sure something could be custombuilt even though the tubing may need to be alitle ovalized in places,its not alot of space left over where the starter transbellhousing(and clutchlinkage if its a manual trans car),floorboard ,framerail and torsionbars are all trying to occupy the same space. 2½" headpipes are available and kind of a tight fit as you may already have noticed.

I know a lot of guys like the 3" exaust sound. But from experience if it were me I would go with 2 1/2". The 3" will cost you some bottom end, enough you will really notice it on the street.

merpar is right. I can tell you this from first hand experience.

Summit sells a A body three inch system from the trans mount back, I used one on my 1969 383 4 speed Dart GTS that I had put stock exhaust manifolds back on after drag racing that car for years with both fenderwell and chassis drag race headers on it. Try contacting Ultimate exhaust, I think that is there name, in Grants Pass Oregon to see if they offer something better
