This winter I am planning on removing all my hotside piping and having it ceramic coated. Should help keep the underhood temps down a little and clean up the engine bay.

So, would the frpp shorties help any with hp or just be a waste of money?

I would think they would help out some....not a whole hell of alot but you should see a gain from them, not too mention they will look a hell of alot better.

no - waste of money

Wiser way to spend the money...

Take your stockers off and have them Jet Hot coated and then wrap the shit out of them in header wrap after

Wont help at all and will eventually crack under hot and cold cycles.
Keep the stock manifolds , if anything just dremel the stock manifolds a little if it makes you happy , but I wouldn't expect any gains.

Thanks everyone, I will just keep the stockers and maybe have them coated. Anyone want to buy some new FRPP shorties? lol

The stockers are basically the same design and size. Just sand them down and pick your choice of coating. You'll have to dremel out the extra cast if you wanna try to wrap them as Pete just mentioned

Im using ceramic coated tuned length jba shorties. After having longtubes on the car and having to take them off for the turbo, there was no way in hell i was throwing those 50lb cast logs back on lol.

Look at the kits that have turbo headers, they arent made from thick ass cast material, its good old coated ss tubing. I agree you may loose a little spool/heat down low, but the gain in flow mid to high range outweighs it imho.

your wrong lightblade. i have done testing with tubular manifolds and factory cast iron manifolds and you will loose some spool up time and you dont gain any more power from them. the stock manis just hold more heat and which makes the exhaust gases expand and makes the turbo spool up faster. the only benefit to tubular is they look better then stock ones. but mine look good here is a pic after i high temp coated them.

by the way i didnt wrap my manis because it would just look like shit, but i did wrap the rest of my piping all the way to the tips and high temp coat it inside and out jus tlike the manis. that alone made my turbo spool up about 500rpms or so faster.

How am I wrong? I all I did was state my opinion. I didnt say they gained any power, and i also mentioned you loose a little down low/spool.

I didnt expect to gain any power, and you cant deny that shorty headers, especialy tuned length shorties flow better the stock manifolds, thats a fact.

I did shorties for the following reasons:

1.Sure aren't hurting performance. Maybe 50-100rpm loss in spool but full spool at 3200 in 4th gear is just fine with me.

2. Weight savings

3. Looks alot better imho.

Thanks for all the info. I may just have the factory logs coated. It will be hard not to bolt up the FRPP'S since I already have them here waiting to go on. I could sell them and put the money into a fuel system.

this is what you said. which they way i took it was better flow meant more hp. and no there is no more gain in flow to be made in the mid to high range. if it flowed more it would make more power.


Nope it doesn't make power but it does flow better. No noticeable power because it all gets stopped/slowed down at the turbo anyways, at least until the wastgate is fully open...

If the stock headers are a restriction to flow n/a they are deff a restriction to flow under boost. Thats why the stock manifolds hold in more heat, they restrict flow and absorb alot of heat. Id rather have that heat energy moving suffering minor losses as it moves through the piping to the turbo, then getting bottlenecked at the turbo rather than bottlenecked at the headers/heads first.

It also just occured to me, i will have less back pressure at the headers/heads when im full spooled and the wastegate is open, dumping to atmosphere. Yes the stock manifolds have more back pressure and hold in heat down low because they restrict flow, which is good initialy for spool. But once the wastagte is dumping i dont want that heat/reduction in flow there.

Regardless everyone sings praises to the stock manifolds which is fine as they work good. My cars running great with the shorties so thats all that matters to me. To each their own. :beerchug2:


And so you dont misinterpret or put words in my mouth "I do not claim that shorties make any horsepower over stock manifolds on a turbo setup" lol

When Mike Bowen was installing my PH setup he talked me out of going with shorties..he said the factory mani's were more durable.
