does some one make a performance single pipe for a 97 sx700, i currently have a bender can looking for a new pipe

or can i use the tripple pipes of a srx (i would prob have to change to a srx hood and change the headers.. )
 
you MIGHT be able to make SRX pipes work if you fabbed up some downpipes, swapped hoods and belly pans, but that's a hell of alot of work. To be sure you're aware, SRX and SX are completely different engines, no parts interchange at all.
 
a spanny is pretty much a spanny, so long as the port timing was roughly the same degreeing as a stock SRX you should make power at about the same RPM, you'd have to fab the downpipes to the proper length to keep your tuned length tho.

flow shouldn't be an issue, it's roughly the same volume, just spin it at the same rpm.

or make a shorter headpipe and spin her up.

fitting the pipes would be biggest issue.
 
If you ever get them to fit, you would want to run them across a dyno just to tune them in. May not give you what you think you would get. For me, it's just not worth the chase. Just find a set of pipes that are proven for that motor.
 
true, but ive seen a couple of srx pipes around on smashed or blown sleds for dirt cheap. My friends got a srx and we are gona see if they will fit on this spring.
 
i have looked into this for my venture. why? you know why ;):D

you are going to need to cut the pipe rest off the front part of your bulkhead.

the length of flange to piston is shorter than on a srx, this means that if you just made everything the same lengt its power would be higher rpm, not sure how much(insert knowledge here).

mounting this way will make using a stock muffler almost imposible as they fit very tight to the back as it is.

also the angle of the exhaust flange is different so when welding flanges on you would need to angle everything a little different.

if you do lengthen the manifolds so the pipes will be normal length the factory muffler will fit better. you will need to move the hole a little and need to add a srx lower and rear muffler mount. also you will have to cut off the battery shelf from your chain case cover. if you have a battery relocate it to infront of the primary.

the easiest way to do this is to use stinggers #$%&* i hate stingers, but if you use them it will make your fit easier and you wont need any muffler brackets and or worry about the shorter length depending on how you do youur flanges.

to start with if you are using stingers use 99up pipes, if you are using stock muffler use 98 pipes.

once your done, do yourself a favor i wish i had done from the beginning, go to a dyno for initial testing, this will save you many hours of screwing around.

i would start with jetting that guys run with power inc center dumps or bender pipes, these would be lower rpm and might get you close.

to get them to fit at the expansion chamber you will need to move the pipe closest to the motor closer and the pipe closer to the bellypan closer leaving a wider space between them for the top pipe to drop down into. also keep tapping with a body hammer to flatten where the shields touch giveing more clearance to get them even lower, it may be nessasary to cut down into the bellypan to ge them low enough. it does look like there will be enough room but i havent done it yet so it may be hopefull thinking. on my viper it was nessasary to cut way down in but the viper has less clearance over the shock on the bellypan than a sx.

dont forget to add a heatexchanger in the back, your gona add 25hp to that sled and power is heat.


as far as saving money, if you worked at mcdonalds for 25hrs at 8per hr you would make up the difference of the cost of the pipes and have a set of pipes you can bolt on, know jetting and clutching without dyno time.

this will be less hours then what you are trying to do.

without dyno time you wont know where to clutch your new conglomeration. you could spend days finding the correct jetting,clutching,rpm combination and that is with a timer.




good luck though, you might beat me to it.

thats all the info i got

if you decide to do it i have alot of cylinders and pistons for sale
 
Scott, Can you get me the difference in the manifold length between the SRX and the SX? if you get me that number, and the main exh port height and I can tell you where it'll make the power. Might even be able to ballpark the jetting.
