AUDIOADDICT02 Posted April 14, 2012 Report Share Posted April 14, 2012 Ok guys, so I have a Ford F250 with a 460cu.in. 7.5L engine and I will be doing a full exhaust swap soon, so my question is this: What setup will give me more power? single 3" exhaust or dual 2.25"/2.5" exhaust with a crossover pipe? I was told not to do dual 3" exhaust because it will "bottom out" the engine & lose power & single 3" will also give me better gas milage, but at my current 9 MPG, I'd prefer power over fuel economy. Hoping someone with experience on this topic can point me in the right direction. Thanks in advance.

ThwopKing Posted April 20, 2012 Report Share Posted April 20, 2012 if you want max power look into headers...but they can get expensive. Other than that replace your mid pipe with new 2.5in pipes and high flow cats...sure you can use 3in but 2.5in is good to 450hp on most engines....way ore than you are making. Then add new piping and really the single or dual set-up is based on what you like more...your mufflr now should be dual in dual out depending on year. But you can add a Magnaflow muffler and new pipes for a couple hundred bucks.

AUDIOADDICT02 Posted April 20, 2012 Author Report Share Posted April 20, 2012 Thanks for the response man. exhaust manifolds will definitely be replaced with headers, vehicle is also non-catalyst. If I do duals I will be putting an x over pipe. I will be doing the exhaust work myself since I have all the proper equipment, I just want to get a sure response wether single or dual is better for more power since I'll be swapping the iron heads to aluminum, aftermarket cam kit, hopefully a tunnel ram with dual carbs & a recurved distributor.

Sethorama Posted May 2, 2012 Report Share Posted May 2, 2012 Dont put a x pipe in. I would do a TRUE DUAL 2.25 or a SINGLE 3in Your gonna get more exhaust flow with the dual system its just all about how u want it to sound as well. Or u can always do TRUE DUAL 3in all the way to the back. or just dump it Quote Link to comment Share on other sites More sharing options...
Keith77 Posted May 2, 2012 Report Share Posted May 2, 2012 I had a 85 F250 with the 460ci in high school. I had a single 3in and loved the way it sounded. I highly doubt that you will notice a difference in performance or fuel mileage if you go either direction. I liked the single 3in cause it had a loud yet tight sound. Quote Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.

I'm trying to reach the 500+ HP mark with this engine so I don't want to risk losing power because of a bad exhaust design.

Did you notice power with that setup? I've been told numerous times that a single 3" will increase mpg, but if the duals get me more power, I figure I might as well do that.

certifiednut Posted May 4, 2012 Report Share Posted May 4, 2012 I would for sure do an x or h pipe, the scavenging effect helps even out, and speed up exhaust flow, as well as helping it sound better, an h is gonna sound a little smoother, but an x flows a little better. If u wanna get crazy, you could fab up a prochamber like MAC makes, and they are the best of both worlds Quote these orphans aren't going to feast on themselves Link to comment Share on other sites More sharing options...

I've been looking around for them, but it seems like they're just "improvised" H-pipes.

ChrisAllen Posted May 16, 2012 Report Share Posted May 16, 2012 For all out performance get long tube headers with excellent merge collectors, and do a true dual 3" system with a cross over pipe. Now, whether you do an X cross over or an H crossover is up to you. For mufflers, get glasspacks, as those flow the most, and sound the best =) Also, consider the sound of an H pipe and an X pipe. Both sound different, and both are very different. Quote Link to comment Share on other sites More sharing options...
