I own a 1989 Ford F150 with the 4.9L I6, 4spd with granny low, 4X4, 4.10 gears, & it's a standard cab long box with only 69,000 miles on it. I'd say that's a pretty damn good truck for $1,000. I was wondering what would be the best route for exhaust on that truck. I would really like to have a throaty cackle type of exhaust that doesn't sound like a rice burner. I've got the stock exhaust on it now besides a glasspack that replaced the muffler & it's got a putter sound to it & it would be really nice to somehow get a throaty exhaust at a decent price.

 

I've heard the best sounding for these is to gut the cats and run a flowmaster series 40. I to have a I6 in a 1994. I haven't got around to it, but I am going to do that same thing.

 

I second the Flowmaster vote. While I have never cared for them on a V8, they have sounded good on every 6-cylinder I've ever heard em on.

 

I bought and installed an Edelbrock cat back system on my truck, and am pleased with it. It sounds a lot better than stock, but it's not obnoxious. Everyone is always surprised to find out I have a straight six rather than a V8. It improved my fuel economy, too.

 

I have the flowmaster 40 system on my 4.9 and I'm not complaining. It blew me away when I first installed it but now I'm use to it.

 

I went with a 2.5" Flowmaster 70 catback and a high flow Catco 9513 cat on my 300. I wanted to remain smog compliant and fairly quiet but with a better tone. I'm satisfied with it.

 

40 series si/do

 

What's si/do?

 

Single Inlet, Dual Outlet, i got the flowmaster 40 series and ran it to the bumper, sounded awesome, got lots of compliments on it also. let us know what you come up with

 

What size pipes did you use & did you gut the cat or just leave it?

 

The inlet was 3 inches and the outlets were 2.5, and i left the cat on b/c i live in south jersey, if i could of i would of gutted it. good luck man let us know what happens

 

Right on man, thanks for your help.

 

no problem ....good luck with it, wait til it breaks in

 

What if I were to just replace the glasspack with a Flowmaster 40 & not do the dual outlet? Would it have the same sound or no?

 

Anyone have any idea what the Gibson super truck exhaust would sound like on an I-6. I too have an I-6 and don't want to get something that would sound like a riceburner.
