Best ory to date

[SSDEUCE]

need an ory for my pacesetters is the tsp still considered the best or is there something better can't take it to an exhaust shop.

kooks or arh

There has been some reported issues with their recent ORY pipes. May want to do some research before you jump into that particular ORY.

[bberretta]

I've ordered the Catted Y from LSXteme Performance- -they have a really nice ORY. The TSP has had some quality control issues, but Kooks and ARH are great quality pipes (they ought to be for the price!) Whatever you order may have fitment issues since you are trying to mate one company's pipes to another. They all angle things differently!

[Vertiviper]

ARH has the best ORY on the market, their merge collectors have a better design and flow better than Kooks.

and im sure you can provide dyno numbers to support your claim

At this exact moment in time, no. However common sense says if something is smoother air will flow past it easier...sorta like a PP TB.

To the OP wondering:

Kooks:


ARH:


The basic difference is the Kooks y pipe is one pipe cut into the other one, whereas ARH has a better, smoother "true" merge design. Both are great designs. I wouldn't imagine the average person would feel any difference, but as we all know all of these small differences add up or show up on the dyno, if you're a dyno queen.

At second glance, it also looks as though the Kooks y pipe on the driver side has been flattened to resolve any clearance issues, I don't know if this smaller diameter would affect flow.

well, lets go back to basic math, the diameter of the pipe changes but the area of the air flowing through is the same, so i disagree. its still a 3 inch pipe just in a diffrent shape. you follow broski? ugh ugh

lmao..i agree the circumference remains unchanged but the diameter will affect the speed of the air...

it's all just apples and oranges, LIGHT WEIGHT

The shape does affect flow- think of it like water- a nice, straight pipe flows water very smoothly. Sharp bends will slow the flow. Changes in shape can cause disruptions in the smoothness of the flow. When applied to air, you create turbulance as you create disruptions. A poorly designed Y increases that turbulance and increases the amount of rasp. The goal with mandrel bends is to keep the flow as smooth and consistent as possible. This is the way I always understood it, but I'm sure there are people better qualified than I am to correctly explain it.

lol all that was left is a argument about ypipes, as if they give you great HP gains if you pick one over the other.

i think we all know there going to net you AROUND the same HP. however, the OP is asking for the best, and as far as clearence/flow kooks and ARH are at the top

Exactly, with the Y anything is going to get you more than stock and they may all net within a couple of HP. I'm still waiting for mine to arrive (next Tuesday or Wednesday) and I think I might be able to the LSXtreme Performance Y to that list.

I think part of the OP's question deals with what's best for the headers he's already purchased. That is going to not only deal with flow but more importantly FITMENT to those particular headers. Anyone out there with Pacesetters have any experience with how the Y's mate up to those headers?

[Vertiviper]

ARH or Kooks are the two top, ARH just has a better design and clearance if you're into that sorta thing.

ehh, thats also arguable broski, the clearence on a kooks y is better than on an ARH y because of where its flattened for EXTRA clearence, which is why you argued ARH has a better flow design. stop contradicting yourself. UGH UGH

[bberretta]

Hell, I'll be happy with my LSXtreme Performance Y for half the price... heh...heh..

You're correct in that ARH found a way to not crush it's pipes to make it fit.

is you look at ARH and kooks side-by-side the ARH hangs lower than the kooks. FACT.

lol,. yes because kooks is crushed

fwiw, every installer I know who has installed both says ARH's tucks up nicer than Kooks..but what to those silly heads know. thilly, thilly heads.
