View Full Version : who makes the x-pipe? flatlander 02-05-2002, 12:36 PM wasnt there someone on the forum that was making the x-pipe for the 99 up gm's? can someone shed alittle light on this please,i went to my local muff shop and they had no clue what i was trying to explain to them...pic's of the x-pipe would also help me out...i did a search on here but no luck....thankz BadAss_2002 02-05-2002, 12:42 PM LoL, how hard was it for them to understand that? Um, I know flowmaster makes a universal one. Dr. Gas makes one also(don't have the website handy). Try another exhaust shop though, maybe they'll know something about exhausts;) CKTA 02-05-2002, 12:45 PM Originally posted by flatlander wasnt there someone on the forum that was making the x-pipe for the 99 up gm's? can someone shed alittle light on this please,i went to my local muff shop and they had no clue what i was trying to explain to them...pic's of the x-pipe would also help me out...i did a search on here but no luck....thankz www.magnaflow.com www.drgas.com www.spintechmufflers.com All three make X-pipes.:) flatlander 02-05-2002, 12:46 PM they said the problem was the o2 was too close and they couldnt weld at that spot. this is why i am trying to get more info on it,what do you do with the o2? move it? Y2K2Sierra 02-05-2002, 12:49 PM You are probably talking about this one: http://sshotrods.com/myrides/gmc/ That is a Magnaflow. I have one in my closet witing for install. I ordered from Husker High Performance http://www.exhaustproslinc.com/magmanbebxpi.html I got it shipped to my house for about $60.

Leave the O2's alone, put the X after them but as close as possible. BTW, my .02 for X-pipe on your truck is a waste, your exhaust will never be equal lengths to warrant the use of a X-pipe. Just get a nice mandrel bent/free-flow muffler/mufflers.

THATS IT!!!thankz y2k2,but i dont see an o2 what did he do with it? just remove it? i'm confussed...and ckta thankz for the link to magnaflow! thats what i want! CKTA 02-05-2002, 01:05 PM Originally posted by flatlander THATS IT!!!thankz y2k2,but i dont see an o2 what did he do with it? just remove it? i'm confussed...and ckta thankz for the link to magnaflow! thats what i want! The O2's are before the cats, the X goes after the cats. Is that what you mean?:confused: Lo Life 02-05-2002, 01:08 PM are the spintech mufflers any good(quality wise), how do they sound compared to flows and magnaflow? i've heard of them but never considered one for my truck until i saw their link above?

I have not heard one in person, however I have talked to a exhaust guy and he says they are awsome! I would have a hard time deciding on the MagnaFlow or the Spintech. MagnaFlow makes them in stainless tho.:naughty: Y2K2Sierra 02-05-2002, 01:14 PM Actually there are o2 sensors before and after each converter. On the passenger side he installed the o2 sensor in the same place on the new pipe right before the x-pipe. Any good exhaust shop should be able to do this. All the have to do is drill a hole in the pipe and then weld on an o2 bung. The passenger side is the only place that you would have to even worry about an o2 sensor. BigKID 02-05-2002, 01:15 PM Na, he didn't remove the O2. Probally just welded in a new O2 bung but you just cant see it from the angle of the pic. Next time I see him I will ask or just look under it myself and see.

John Cannon gave me the info on where to get it. I got mine from Extreme Speed and Performance in Mobile, Alabama, phone (334) 341-1900. Mark Evans is the owner and a great guy to deal with. Got mine Friday. John relocated the 02 after-cat sensor on the passenger side. He sent me the following link to show the relocation of the sensor and X-pipe placement; www.sshotrods.com/media/sensors I get my exhaust done 2/16, can't wait. dhill_TX 02-05-2002, 06:28 PM Originally posted by flatlander THATS IT!!!thankz y2k2,but i dont see an o2 what did he do with it? just remove it? i'm confussed...and ckta thankz for the link to magnaflow! thats what i want! I just did exactly this to my truck... Here are some pictures: http://community.webshots.com/album/29543995smubthrZVb More X-Pipe info: http://www.kinneysmufflershop.com/x-pipe.htm C3Sierra 02-06-2002, 10:15 AM I understand the concept of the X-pipe but I have only seen exhaust systems use them that had equal length pipes. I would think that you would not get the same beneficial effect with both pipes running down one side of the truck (unequal lengths) or at the very least it would be a gamble that you would place the X-pipe where one side had an exhaust pulse and the other doesn't. If due to the unequal lengths of pipe you actually experienced pulses on both pipes then there would be no benefit. Does anyone have any actual dyno numbers to show a hp benefit with unequal length pipes? I have seen dyno numbers that showed an X-pipe exhaust actually flowed better than an open exhaust. This is strictly due to the scavenging of exhaust gases. When one pipe sends an exhaust pulse it actually creates a vacuum on the other side that sucks out the exhaust gases from that sides head. This in effect acts like a bigger cam for the exhaust side. I do not believe it would be nearly as effective if it had to do this after the catalytic converters.

CKTA 02-06-2002, 11:06 AM Originally posted by flatlander so are you saying that on an exhaust system like mine it would be better to go true duals without an x-pipe? because of the different lengths? I said that in the first couple of posts!:D flatlander 02-06-2002, 11:26 AM Originally posted by CKTA I said that in the first couple of posts!:D sorry ckta but 99gmc said not to listen to anything you have to say! j/king...i was under the impression that you should have some type of x or h pipe in your system?

You will not see benifits unless you have equal true dual pipes. The only people on this board that can make use of a X or H are the guys w/ '87 and older bodystyle trucks. Now I know there are people on this board that have them on newer trucks and say it gave them performance......well fact of the matter is no one that I know has a dyno in there backyard......so most likely not. flatlander 02-06-2002, 12:00 PM Originally posted by CKTA You will not see benifits unless you have equal true dual pipes.

CKTA 02-06-2002, 12:09 PM Originally posted by flatlander o.k. so true duals without any type of crossover is better for 99 up? Yes, if you want "true" dual pipes. The X will just be a waste of time and money. BTW, anyone w/ a '96 and up Vortec C/K truck same goes for you. And....anyone w/ a '88-'95 C/K you can do a "true dual" if you want, but a single 3" intermediate pipe is also more than enough. flatlander 02-06-2002, 12:26 PM o.k. thankz ckta,found a guy in the next town over that does SS exhaust systems so ill get with him on it.... now i just gotta figure out an exit for it. thankz again for the help everyone! justin 02-06-2002, 12:26 PM Originally posted by CKTA Yes, if you want "true" dual pipes.

You're telling me that won't give me more performance?? :p You know, they COULD make an xpipe be useful, but it would be a ton of work and require ditching their entire current exhaust and probably cost about a grand, but it COULD be done :assclown: CKTA 02-06-2002, 12:31 PM Originally posted by justin :( I was wanting to rig up an X-pipe before the Cat, and then an H after it.

That's not what I read, but whatever!:D bigred305 02-06-2002, 12:51 PM I have been wondering, because I knew that I had equal length pipes on my truck, so I guess that means that I "could" see a benefit with the x pipe even if it was a small one.....

I wouldn't go anywhere else. :D Yea, I was pretty impressed with them... I forget who recommended them, it may have been you. :) At first I was pissed when I saw them spray painting, but the more I look at it, the better it looks... FeatherFoot 02-15-2002, 11:06 AM X pipes and H pipes will work on any exhaust system IF it is done right. My method to install is as follows: paint a stripe down each pipe and start your engine. run it at a high idle (1000 rpm) for a minute or so. Check the paint for blisters. connect the two pipes where the blisters stop. This may be a foot down stream frome oneanother but this is what works.
