2.5 or 3.0 exhaust
 

Im going to redue my exhaust next summer(take me that long to save up) but i was bored so i was thinking about it. If available yet i want the dynatech longtube header kit, except the y pipe. I want to put in a x-pipe instead of the true duals to gain that low end torque that all of you guys claim im losing. also i want flowmasters instead of the magnaflows i have on now(to quiet for me) but since im getting the x-pipe would it be ok to have the 3 inch exhaust pipe, the reason i want 3inch is because dad has that on his 04 F150 and it sounds amazing(flowmasters). or should i just stick with the 2.5inch exhaust

also if i have enough saved up i want the 80mm throttle body and ram air hood:cheesy smile: and getting my tunes redone.

Sounds like you've got your mind made up!

Suggestions taken?

Here's my ideas

OBX headers.
High flow cats.
Rear o2 delete.
2.5" piping.
Xpipe.
Borla xr1's mufflers.
RAM air hood.

The 80 tb ain't going to do you any good unless you pair it up with a supercharger.

thanks i guess what i really was asking is if i will still have the back pressure needed to get that low end torque if i used the 3inch pipe. i guess ill ditch the tb out for now.... still a couple of years away from a supercharger:thumbsdwn:

do you know of a website that has the obx headers i cant find them for trucks.

I'll look.

I'm still looking for 09 availablity.

Is your truck 2wd or 4wd?

I think the 09 drivetrains weren't changed much from the 04-08.

These might work? 4wd

thanks thats all i could find when i looked on ebay. i couldnt even see if they sold them from their own website. All i seen was for cars and not trucks.

But they are alot cheaper.
