Core Power Plays

The specs and strengths that make it shine.

Discussion about different bolt options

“I wonder if FelPro, or APDTY is better?”➕

“I probably paid as much for all of them as he's trying to pay for 1 bolt.”➕

“$39 on Amazon for ARP bolts.”➕

Discussion about experiences with Dorman products

“What is everyone doing for intake manifold? Dorman?”➕

“Dorman is junk, or Bullitt intake(expansive)”➕

“You could tell the difference in power.”➕

Discussion on the reputation of aftermarket catalytic converters

“Dorman is just as good as OEM, and is roughly third of a price.”➕

“Visually looks identical to OEM, same flex pipe as OEM, not mesh type.”➕

Comparison with other headers and their performance

“Splurged on the banks and it bolted up perfect and all the little problems went away.”➕

“It's holding up fine for about 40k miles now.”➕

Discussion on using quality gaskets for better fit

“Make sure to get a good felpro gasket, don't use the cheap ones that usually come with them.”➕

Hidden Hero Hacks

Unexpected tricks and side‑door uses you’ll love.

Suggestions for using alternative materials for quick fixes

“If it only needs to pass inspection, I would braze it, and then paint it with some high temp header paint.”➕

“There is a high temp putty that you can get from most auto parts chain stores that is good up to about 2400°f.”➕

Buyer’s Cheat Sheet

What to check before you click ‘Add to Cart.’

Discussion about aftermarket vs. OEM manifolds

“The downside is that the design hasn’t changed and so they will eventually crack again, but maybe that doesn’t matter since I doubt I will own the car for the 8-10 years it will take to do so.”➕

“Just use an OE manifold. They obviously come with new cats and other than occasionally cracking don’t really have any other problems.”➕

“I am about to do the work and after talking to a few mechanics they said it is unlikely I would feel gains of the after market and the OEM are good enough.”➕

“I’m probably too skeptical to go that route unless someone can recommend them.”➕

Discussion on OEM vs aftermarket parts

“It’s the one thing under the hood that absolutely looks like hell.”➕

“I'd recommend oem unless you don't have to do emissions testing where you live.”➕

“But that’s a temp fix.”➕

Discussion about limited options for exhaust manifolds

“Who else is rocking the infamous Dorman intake manifold? 🤣”➕

“Can you even get anything else at this point on short notice considering the OEM part was discontinued?”➕

“There really isn't any other option, hopefully someone will prove me wrong.”➕

Consideration of alternatives to Dorman

“The best route, I went trickflow myself, but not everyone has $800+ to drop on an intake manifold.”➕

“Very much good intakes to run as a basic reliability upgrade, even if you have no plans for future mods.”➕

Curiosity about alternative kits for exhaust manifolds

“I did find that actually, good looking out!”➕

Discussion on the value of Dorman bolts versus cheaper options

“Are the Doorman worth paying 3x as much or do they last no longer than the cheapest?”➕

“Dorman is typically better than oem.”➕

Discussion about Dorman part numbers and compatibility

“if you search for it.. you will find its cheaper to replace it.. than it is to get it welded.”➕

“it will probably take too long by the time its sent from the usa anyway, need a quick fix before registration lapses.”➕

Curiosity about engine modifications

“A lot of people hate these mounts, but they are fantastic if you don’t overtighten them.”➕

“I’m curious to see the difference. They’re supposed to be worth a few extra ponies mid/top end.”➕

“I will say, after doing the motor mounts, off the line it feels like I picked up +30 torque.”➕

“They are fantastic, I had a similar experience.”➕

Cautionary Callouts

Know the pitfalls before they catch you off guard.

Discussion about the challenges of exhaust manifold replacement

“I believe that D. Thorley long tube headers will mount right up no issues but anything else needs more fabrication.”➕

“In my opinion just get the DT LT’s. OEM manifolds will crack eventually.”➕

“Cost savings are real, just gotta vet your people.”➕

“I'm not paying that kind of money for exhaust manifolds.”➕

Discussion about installation challenges

“That’s what I saw on the video too I have to do the driver side rear.”➕

“Thanks for the video and tips. I will let you know how it goes.”➕

Discussion on bolt options for exhaust manifolds

“Curious on what others have done to deal with the notorious issue with an aluminum head and steel bolts and a steel manifold.”➕

“Get some arp grade 8 exhaust manifold bolts. It’s worth it.”➕

“Do you know which pack to get from ARP?”➕

Challenges in exhaust manifold repairs

“I don't want to let it get worse.”➕

“If you remove the manifolds, just expect to snap more bolts.”➕

“Honestly, unless they're pretty experienced with these sorts of repairs already, just go with the Dorman clamps mentioned.”➕

“Headers do need a tune but I picked up about 20 hp once it was all said and done.”➕

Discussion on experiences with exhaust manifold repairs

“It's clear my budget is 10 year old Fords with factory issues 😅 that's okay.”➕

“I don’t think you have to pull cab experienced mechanics can do it in like 45 minutes though.”➕

“It's a shitty job.”➕

“Replacing the manifolds I thought was the easiest and quickest out of all of them.”➕

Discussion about the longevity of Dorman products

“Dorman Exhaust Manifold a Good Option?”➕

Concerns regarding the use of aftermarket parts

“I am glad to hear that the Dorman has a chance of holding up.”➕

Advice on using longer bolts to prevent breaking

“If you want them to stop breaking you need 1” longer bolts and 1” spacers.”➕

Advice on replacement versus temporary fixes for cracked manifolds

“if you're removing it, you might as well just replace it.”➕
