abakja1 Posted July 28, 2005 Share Posted July 28, 2005 http://legacygt.com/forums/showthread.php?t=15539&page=3&pp=10&highlight=fire Just getting more info on the above thread,.. Scotty overcharged me on my Stromung twin tip, so instead of getting a refund, I asked to just send a shorty DP to me instead,.. After reading about the fire in the above thread, it scared me,...Probably a isolated incident and more to do with the rewire of his O2 sensor, but enough damage to ask "how many of you are wrapping your dp" and is everyone doing this?? I know I couldve got the Crucial DP, but $300 compared to $200 (I paid just $75 more after refund from Stromung) is a small difference,.. Now, from what I know, I should trim any material on the firewall close the the dp, reuse my "modified" heat shield, and zip tie any loose wires. But should I and really need to use heat wrap and spray for a shorty?? Link about the heat wrap said that it would also damage the pipe in a few years, so that is a concern,.. Should I worry about a fire, or was it bad luck on that guy's part??? abakja1 Link to comment Share on other sites More sharing options...
Ridgeracer Posted July 28, 2005 Share Posted July 28, 2005 Personally I think its a better idea to wrap the wiring with high temp tape and secure them properly than to wrap a pipe. Also most companies don't warranty there pipes that long if you install heat wrap. 02 cents..

Guest *Jedimaster* Posted July 28, 2005 Share Posted July 28, 2005 Get a coated dp like Crucial and avoid fires altogether. Link to comment Share on other sites More sharing options...

powbmps Posted July 28, 2005 Share Posted July 28, 2005 It would be called stupidity, not bad luck. Avoid cutting the O2 sensor wiring at all costs. Ima Hacque Link to comment Share on other sites More sharing options...
NHLEG Posted July 28, 2005 Share Posted July 28, 2005 does crucial make a DP with a hi flow cat? If they did, I'd have it to go with my Crucial UP . Link to comment Share on other sites More sharing options...
illt3ck Posted July 28, 2005 Share Posted July 28, 2005 If they did, I'd have it to go with my Crucial UP . They make a shorty which takes advantage of the 3rd cat. Link to comment Share on other sites More sharing options...
abakja1 Posted July 28, 2005 Author Share Posted July 28, 2005 I would have loved to do the Crucial dp, but needed only to spend $75 more to get it,..For those of you who have dp already,..what precautions have you taken or have you seen any problems?? Do I really need to wrap my Helix up when I install it too,..Basically, just want to do any preventative/reliability measures so I dont have to do the same job twice. I know that I-Club members with full exhausts on their WRX/STIs dont have wraps,... I guess the cheapest precaution for me like Ridgeracer suggested is to thermal tape any wiring and maybe put some thermal tape on the firewall insulation too instead of doing any cutting,.. any other suggestions?

KTM 525 Posted July 28, 2005 Share Posted July 28, 2005 I am putting my COBB DP and Crucial; UP in on Sat. The DP will be wrapped and sealed along with blanket wrapped around the turbo itself. Link to comment Share on other sites More sharing options...
jim1969 Posted July 28, 2005 Share Posted July 28, 2005 are you guys using the copper gaskets from crucial or the OEM ones? Link to comment Share on other sites More sharing options...
KTM 525 Posted July 28, 2005 Share Posted July 28, 2005 I personally am using the OEM on the DP and the copper ones from Crucial on the UP. Link to comment Share on other sites More sharing options...
jim1969 Posted July 28, 2005 Share Posted July 28, 2005 I'm planning on doing the opposite once I get my dp from crucial. Link to comment Share on other sites More sharing options...
NHLEG Posted July 29, 2005 Share Posted July 29, 2005 They make a shorty which takes advantage of the 3rd cat. I don't see any "advantage" to the 3rd cat. I know the 2nd is the most restrictive, but the 3rd ain't much better. I went w/ Cobb because of the HFC they use and how far down stream it is...basically where the 3rd stock cat is, just much more efficent. Link to comment Share on other sites More sharing options...
Guest *Jedimaster* Posted July 29, 2005 Share Posted July 29, 2005 But you'll notice the difference with the shorty- I had one on my WRX and left the stock 3rd cat. I'll bet adding a hfc wouldn't be anything you'd even feel in the seat of your pants. Link to comment Share on other sites More sharing options...
abakja1 Posted July 30, 2005 Author Share Posted July 30, 2005 I probably will themal coat the dp, still debating about the Helix uppipe though,..the Helix uppipe looks really nice being all shiny and all,.. BTW,..Does the heat coming off the uppipe have any hazards like being too close to any wires or contribute to the 3rd cylinder premature wear that Im unaware of (read in a Nasioc post)?? Cause if not, I wont coat up,..well if the cost is not much more when I coat dp,..maybe I will, but will hate to see the "bling factor" go,.... will make my decision on more inputs till the dp arrives,..

powbmps Posted July 31, 2005 Share Posted July 31, 2005 It shouldn't be a problem as long as you keep the wiring away from the unshielded dp. I ran that way for three years in my WRX without any issues. Link to comment Share on other sites More sharing options...
YBNormal07 Posted July 31, 2005 Share Posted July 31, 2005 I've wrapped and sealed 3 dp's...one on my WRX, one on my STi, and one on my LGT. As long as you use a lot of the sealant to keep moisture out, there will be no ill effects to the DP. For the price, I say it is worth the effort. Coating is nice, and the real think ceramic coating works very well, but it's a lot more expensive. Link to comment Share on other sites More sharing options...
abakja1 Posted August 23, 2005 Author Share Posted August 23, 2005 Ok,..finally got my Helix flex uppipe and Stromung Shorty dp back from my ceramic coater,.Its a 1500-2000 deg ceramic coat and he didnt coat the flex section at my request,..just in case it may flake off cause it does flex,... http://tinypic.com/aynlsz.jpg http://tinypic.com/ayo6br.jpg Link to comment Share on other sites More sharing options...

Crucial Racing Posted August 23, 2005 Share Posted August 23, 2005 I highly recommend heat wrapping a bare steel downpipe if you already have one, ESPECIALLY on a Legacy w/ the small hood scoop. A bare downpipe radiates an insane amount of heat essentially right under your intercooler. ...just look at how much exposed downpipe is inside of the engine compartment... The intercooler heat soaks fast, which is actually a dangerous condition because your car has no clue. The intake air temperature sensor is integrated into the MAF sensor. The ECU adjusts timing based on the temperature as seen by the MAF sensor, and it assumes a certain intercooler efficiency. The car doesn't know the actual temperature of the air going into your engine (post intercooler). Sit at a stop light for a minute or two and drive hard shortly thereafter and you are likely to see detonation. It's really a somewhat retarded system.... Anyhooo -- definitely go nuts with the sealant spray on the heat wrap. Any fluids dripping onto the wrap and soaking in can lead to fires. Even the spray can't keep condensation from being held against the metal though. This is my old downpipe after 20,000 miles. This is a really high-quality downpipe, btw... and it saw nearly all of its life in CA... limited amounts of rain, only two trips where it saw snow for a couple of days. http://www.wrxfanatics.com/uploads/post-24-1123566300.jpg So yeah, I'm a bit biased, but the cerametallic coating on the Crucial pipes does a really, really, really good job of keeping the heat inside of the pipes where it belongs, as well as protecting the metal from the corrosive elements in the exhaust gas and from the weather/outside elements... And for those who wanted a high-flow, Crucial will be releasing a high-flow 3rd cat pipe in ~ a month to 1.5 months. Its design will make more sense than the current ones available, and I'm going to make it as affordable as possible with, of course, the usual Crucial quality and Lifetime Warranty Jeremy Link to comment Share on other sites More sharing options...
abakja1 Posted August 23, 2005 Author Share Posted August 23, 2005 Where did you get the coating done at and how much does it cost? Probably not worth your while cause I live in Hawaii,.. But I got it done at a place called High Tech Coating,.. Cost me $150 for up and dp,..or $75 each,... Link to comment Share on other sites More sharing options...
