OBX Headers

[cbrtrx]

FRPP is 2.75", but it looks like proximal end (closer to header) is necked down to slip inside, so might need a 3" ID to 2.5" ID to accommodate, or cut the 6" off of it and use one of those 6"long 3" ID to 2.75" ID neckdowns?

FRPP x pipe is 2.5, it necks down to 2.25 at the factory connection.

FRPP x pipe is 2.5, it necks down to 2.25 at the factory connection.

The Ford Performance Cut and Clamp Resonator Delete X-Pipe (15-17 GT) will be 11.35lbs, is 33" long, and the piping size is 2.75".

Is this not true?

I just ordered mine (resonated maximizer) for $408 shipped. They are the 3" mid pipe as well, figured I'd have to use these https://www.summitracing.com/parts/wlk-41687/overview/
to get it to match up to FRPP x pipe. Thoughts?

Me too got a set of Maximizer headers shipped to PR for less than $500..Hope they fit and perform well. Seems similar to OBX/TSP units. Ill report once they arrive.

I'm 99% sure they are identical to mine except not polished. I didn't wanted polished honestly so I should have just gotten those not sure why I didn't.

Maximizer is OBX without the polished finish.

Good to know. Has anyone dynoed this things..OBX/TSP/Maxi..? At least want to get over 400whp with these. Right know Im at 390whp auto equiped car.

Should perform just as well as top brands or close. You are removing cats and allowing more flow with larger collectors. Fitment is another thing tho but from what evryone has said it looks like it should fit np. I also picked mine up this past week, arrived Saturday morning. Would of been less but home state tax...

Any tips for self install? I remember reading somewhere people were flipping ac bracket for clearance and also pushing the motor to one side when buttoning up?

Should make the same power as any other 1 7/8 header made for that area of the car.

Looking at your pictures they are exactly the same without the high polish. I didnt want polished either and even these seem a bit bright. They have the same "collectors/merge". Nicer than I expected for the money, just wish they had the bolt up flanges for easier swap.

I'm somewhere at or just north of that on E-85. Virtual dyno shows 450whp and it showed 375 whp stock which seems about right. Gears 1-2 are useless at wide open throttle even in warm temps at this point and I've got crappy 3.31s and 28" tall tires. I'm thinking I'm close to or just over 400wtrq with how aggressive my timing curve is.

Brush them with course sand paper. I thought about doing that to mine but decided not to spend the time on it because you can't see them anyway.

I have installed a few of them, they are 2.5. The factory connect part is 2.25.

I installed my headers this weekend and the extension pipes after the resonators are about 3 inches too short. I need to add 3-3.5 inches to get the exhaust to hook up.
