He recommends H pipe, and i recommend X pipe, maybe you re-read my post?

i cannot see an H pipe perform better in any way. You do not want to keep anything separate in an exhaust or intake in N/A applications. Using an X pipe will blend exhaust pulses together so as bank 1's pulse will scavenge bank 2's exhaust pulse efficiently and vise versa.

An H pipe, I feel is to square to flow well enough to scavenge as efficiently as a good X.

The pulse would have to make 2 hard non mandrel bent 90 degree turns where as the X pipe is blended and its just a change of direction rather then flowing an entirely different path all together. Also the length of the pipe the pulse travels isn't changed either as they meet at the same point and no matter witch way they turn theres the same distance to the tip.

Either way, i doubt the change from X to H is incredibly noticeable as it effects flow only at its near highest critical speed inside the tube, and at that type of flow horsepower is more effected then torque witch can not be felt.

 

didnt mean any offense, I hope you can see where I misunderstood you?


nevertheless neo thanks for the input, I appreciate it.

 

its cool dude, no problem. just the internet.

 

I use 2 1/4 stainless steel piping with a magnaflow x pipe.
For maximum reliability and years of service make sure all piping is stainless steel and not aluminumized.
I can always hear a tinny weak sounding exhaust by the high pitched noise coming from it . I have no droning and no pulsing with only 2 L-sportline exhaust and a complete new set of pipes right from the cat which needed to have the o2 sensors re welded on to give more clearance and rebuild much better Y's.

 

In Texas the muffler guys will not touch the O2 sensors. It is cool you were able to move them as that is the only place on my car that still hits on higher speed bumps. For now I am stuck with that area being lower but atleast all the resonators are gone. I used aluminized rathe than stainless to save bucks - sounds like you went first class

 

yea, good call dont know if they will move them or not here in colorado and neo as to your last post, it sure does sound like a "sound" decision to me

 

Hehe..

Yeah good call on the stainless through and through.

I thought about that,.. your catalytic converters are going to turn the combustion gas's into harmless water.. That water will run down your exhaust pipes, and often just sit in there.

If the inside isn't stainless then it will (eventually) rust through. Stainless will make a big difference, although it takes a long time for the pipes to rust through from the inside out. So if you don't intend on keeping the car for more than 5-6 years,.. not a huge thing to go with aluminium. (imo)

 

yea though im in the works of turning it into a show car/ daily driver lol so i would like to keep it if the motor goes im going to get a new one soo... might as well go with stainless since it looks better too!

 

lets be clear, aluminum CANT rust.

ur talking about aluminized STEEL tubing

 

lol correct you are but isint it just easier to type aluminum hehe!
