hey do you guys think an x pipe would still be worth some horsepower on an exhaust that has no bends in it and dumps at the the rearend? thanks bob
the cross pipe, properly installed creates a scavenging effect in the opposite pipe causing less restirction on the pipe the same, but not as efficiently as the collecters on headers. The power gain is not something you can feel in the seat of your pants but every little bit helps.
Sooooooo, Per say...... If you have a 550-600hp motor, are you going overkill if you run say a 2" primary header and a 3" system to the back. I have the headers and exhaust, but not on the car yet. Motor not done yet either, but shouldnt be long. Just trying to plan ahead I guess. If I have too much header or exhaust, I would like to know now verses finding out later. Aslo if this combo is ok, the x-pipe still the way to go?????? Or is the 3" so large, theres little to no backpressure to equalize? Quote:The larger diameter exhaust pipes and mufflers dissipate heat, causing the volume of the exhaust gasses to be reduced. This characteristic enables smaller diameter tailpipes and in some cases, even a muffler with a smaller inlet and outlet to be used. The benefit of this heat loss was apparent when we contrasted the back pressure values of the same muffler mounted in two different locations. Kinda wanna do this right the first time. Wallet and the wife both agree.......
PS, Thanks for the link Jim Lore. Did you sell that 70 grill trim I saw mentioned in another thread? I might be in need if you havent.......:TU:
I have had 2 installed this year. One was a BBC car that I did notice a difference in the seat of my pants. The other was a 455 car with total new exhaust. It did make a big difference, but was due to many changes and not just an X. I would say go for it.
thanks for the info guys. heres another one for you, when you put the x pipe on do you want to put it as close to the mufflers as you can or do you want it as close to the headers as you can? bob
