took my time doin this job about 4.5 hours from start to finish including dinner and plenty of beer. Everything went amazingly smooth minus the clamp holding the DP & cat to the rear of the exhuast (angle grinder and boom done) after splitting it i removed all the hangers and took them off seperate from the car. the downpipe gave me a few issues such as the SAS bung. little bugger took over an hour to figure out how to get the pipe out with it installed (couldnt get it off even with PB & J blaster.) so seeing as my SAS pump is kicked why have anything else associated with it. so we did some modification (aka bending) of the pipe then slid it out. Fantastico. removed the 02 sensors and placed them in the new ehxaust (test pipe no cat) got myself a nice 18mm spark plug anti-fouler and drilled it out with a 1/2" bit and slapped that in the post (cat) bung and no CEL yay. everything went smooth and shockingly to every other install post i had no major rubbing issues. there is only one where the downpipe comes through above the sway bar and cross member it rattles if i go over a bump with my wheels cocked to the side. but other than that rattle free. The tip sticks out a bit to far for my liking but nothing i cant have fixed up after the fact. <p>although no CEL i might be having 1 slight issue. When im on it on it i studder at 3.5k rpm. this is about when my boost gauge bounces from roughly 15 psi back to is 10.5-11 ish. is this studder because of overboosting situations or is it a misfire. i dont have a CEL on (minus the SAS pump thats been bad for say a year now) so i am curious to why it does this now. Vacume is still at 18hg at idle and i replaced the vac lines, new MSD ignition from IPD and new HD TCV from them as well.<p>I will say i LOVE the power and you can definatly feel it as so did my tires (they are already bald so oh well)<p>One beef with it (they did make a small indentation on the downpipe so that you could get something onto the rear top nut for the turbo... but nothing fits in it so it was a mighty pain in the a** to get it on tight. its snug but not snug enough so i have a tiny tiny leak that disapates as it warms up. the only way i can think to tighten it more is to cut a 13mm wrench in half so i have room to tighten. sorry for the 0 pictures i uploaded i sorta forgot the camera <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/frown.gif" BORDER="0">

Re: (S70GLT)

i think it sounds great. i was afraid when i was finished putting it on that it would be honda-ish but i was very wrong. it sounds fantastic, nice an throaty. little grumble at idle which i enjoy and a nice note all the way through. its civilized on the road at speed and basically anything under 3500rpm you can hear it pur along but nothing annoying and i didn't have any drone. when you step on it you notice it a lot.. in power and sound. it screams all the way to 5600 and keeps pulling. defiantly a power you can feel. the install wasnt that bad minus they didnt leave me tons of room on one of the turbo bolts but i worked around it. no rattles at all just take your time putting it on dont try to rush it. after selling the angled flange DP it cost a total of 350 ish so i felt DEFIANTLY worth it and would do it again in a heart beat if i had another volvo haha

Awesome man! I just got mine on as well. I had to extend my rear O2 wires and my rear hanger didn't work I had to build a new one. I went ahead and chopped off about an inch or so off the pipe and re-welded it to pull the tip in flush with the bumper. Then I painted it all flat black with VHT header paint since I hate shiny crap. Looks and sounds mean as hell. <p>It really woke your car up huh!? I was amazed.

Re: (jrodT5)

yea it was very nice. i was planning on doin exhaust wrap on the whole thing but i kinda dont have a job or money so that fell through. i have SAS and no bung haha so im lookin into deleting it. also i have to rig up my spacers cause i forgot to bore out the 2nd one so there isnt enough air flow basically. look in the new 09-10 IPD catalog and their new full system exahust is the OBX ehxaust with a SAS bung in it, a high flow cat in it, and a new tip. im so happy i got mine and now that IPD is using it haha but im also glad i got mine for 350 (thats after i sold the 2nd DP)

Nice man, yah I left my SAS bung out and just have it all still hooked up. No codes yet, the airpump is worthless anyways. I got 2 spacers off ebay for $8 used one on the rear and have a spare.

Re: (jrodT5)

i have everything connected too including a recently pulled new to me SAS pump and its working but im getting the code P0440 and it might be the SAS but when my pump died it actually said secondary air injection blah blah so this might be the purge valve needing to be replaced. i hear the pump running and air coming outa the unconnected check valve haha. <p>as for the 02 spacer i just bought a 2 pack of spark plug defoulers and bored them out with a 1/2 inch drill bit and put em together then put it in the straight pipe then add the 02 sensor. i have a code but i forgot to bore out the 2nd spacer so theres only a pin hole in it so its prolly not getting enough air if any at all to get any type of reading. ill remove it then bore it out tomorrow and see if the P0136 code goes away. I do love love love the new IPD exhaust because short of a round tip, a cat converter, and the sas bung i have the same exact one just 1/3 the price <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0">

I'm going to install my OBX this weekend and I was wondering how KurT5's defoulers worked out? I don't know whether I should bore out both defoulers to 1/2" or just the second one? <p>Also I am unclear, do you put two 18mm defoulers together, one on top of the other, and then the O2 sensor? Or do you just need one? <p>I also take it that you don't install a defouler on the front O2 sensor correct?<p>Thanks

I used one spacer on the rear O2 sensor, you DO NOT need one in the front. I don't think 2 are needed but I didn't use defoulers I used a spacer off ebay. <p>

Re: (jrodT5)

Congrats. OBX makes the best budget system period. Good time on the install too. Did you have a lift or did you struggle with jackstands?
