who makes the x-pipe?

[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

[BadAss_2002]

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;)

www.drgas.com

www.spintechmufflers.com


All three make X-pipes.:)

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?

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.

The O2's are before the cats, the X goes after the cats. Is that what you mean?

[Lo Life]

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.

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]

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.

Magnaflow makes the X-pipe (part # 10789). 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.

I just did exactly this to my truck...

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.
