it would be very difficult to have straight pipes, unless you wanted to loose all your ground clearance, so i'm assuming you're meaning true duals in a bendy fashion. if you're mostly stock, 2.5 might loose you some low end torque, but if you keep some cats in it, it shouldn't be too bad

I think he means no cats and mufflers, with the normal bends for dual exhaust routing. Not literally STRAIGHT pipes.

Ha...gotcha. When I think of straight pipes, I'm thinking 70's and 80's Ford pickups running straight to the back. But anyways...I think that would sound LOUD. REAL LOUD. I know what mine sounds like with open headers, and that probably wouldn't be much different.

yeah, you'll just lose some bottom-end power, nothing serious though

When I drove my car from the dealership to the exhaust shop it only had the manifolds and front two cats, pipes cut immediately afterwards and it was annoyingly loud...to the point that it hurt my ears a tad at part throttle. I thought it was cool when I first started it up because I was used to a quiet exhaust, but that wore off real quick.

I ALMOST have that setup. See sig below. But I have 2.25'' true duals, x-piped all the way back. But i have my stock cats on. This is a loud setup as is. You definetly can hear me coming lol. Without ANY cats you'd be screaming. Only crappy thing about removing cats is low-end loss, and when u get on it or let off while in high rpms it will pop and crackle lol. Plus this might create some visible smoke in your exhaust fumes.

Sold my Cougar . But I am in the market for another MN12 project!

That's how mine is, I love how it sounds. I love to roar by people that are going slow, they hear it coming and they're like WTF!? But someday when I have better income (and my cats clog up), I'm gonna get true duals, no cats, into 2 Flowmaster 40's. Hoping that'll be just as loud, with no worry of cats clogging. While this can't be considered straight pipes due to the fact that there are Flo's at the end, it should still sound good.

Not to hijack your thread...I agree with the above-mentioned opinion that 2.5 is a bit large for a stocker, but if you're gonna make more power, I'd say go for it.

My 4.9L F250's exhaust fell off after 250,000 miles. It was replaced with a new manifold and one pipe (no cat or muffler) running back following the stock routing, was really loud although it didn't sound too refined.


Whoa! with all those stickers and that huge wing your car must have like a million horsepower.
