ok... i have the k&n filter deal installed and now it's time for some exhaust. my question is would a 40 series be "too loud" or should i opt for the 50 series for suv's and trucks. i think that i was told to get the 40 series by a rep at white's pit stop here in lansing, il. our local race shop. also does anyone know if my 94 xlt 5.0 has 2 1/4 diameter pipes or 2 1/2? on the flowmaster webpage it has the single inlet with the dual outlet. that's what i plan on going with. thnaks in advance.
Yeah... the 40 series on the factory exhuast is about as quiet as a stock Camaro. Its really pathetic too, on my 88, the cat's are really plugging up the system with 187,000 miles on them, so I just run straight manifolds for now Less stinky, about the right noise level too
Try to get some aftermarket cat's on there if you want to here something good, otherwise, after my mistake, I wouldnt get anything new on the exhaust system unless I was totally replacing it.
I have a Flowmaster Series 70 Muffler on my 1984 Bronco with 2.5" duals coming from my 460. Sounds good.. nice rumble..
Broncos are a PITA for putting true duals on.. not much room under there.. I have the exhaust coming off the headers.. through 2 cats, into the Dual in/Dual out Series 70 Flowmaster, then exiting just under the rear bumper at 45 degrees on both sides....
