Max Capacity Posted December 17, 2021 Share Posted December 17, 2021 The other day, someone posted a picture of the heat shield they installed over the cat on the Dp to protect the axle boot. Can whoever posted it, please do it here. Thanks. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Max Capacity Posted December 17, 2021 Author Share Posted December 17, 2021 (edited) Thanks, ordered.

leetdrv Posted December 17, 2021 Share Posted December 17, 2021 I was thinking about wrapping my entire COBB DP to contain heat and prevent rust. Will this shorten the life of the cat? Link to comment Share on other sites More sharing options...
Max Capacity Posted December 17, 2021 Author Share Posted December 17, 2021 (edited) There is a thought the wrap retains moisture, causing rust. Here's why I'm replacing the Dp on my Spec B. I bought it used, wrapped about 8 years ago. Had to check my book, I didn't list when I installed it but the GS tmic was done May 2 2015, I know the Dp was before that.

Enlight Posted December 17, 2021 Share Posted December 17, 2021 +1 to what Max said, the wrap will retain moisture. After a rainy day you'll find your undercarriage will be mostly dry while the wrap retains moisture. It will also collect the dew that percolates from the ground. - Someone who wrapped their headers and downpipe muFreight.co A JDM Container Sharing Service from Japan to NYC Website | Instagram | Email Bessie II's Thread Link to comment Share on other sites More sharing options...

Unless you only drive less than that and were in total slop is it going to retain moisture. Max's was used when he instslled it 8+ yrs ago. I think he got his moneys worth. I ended up wrapping my Cobb DP about 14" from the top down. I will end up installing one of the DesignEngineering shield/wraps on the DP to protect the half shaft boots from degrading....further.

My opinion. Sent from my SM-G996U using Tapatalk Yup pretty much, I figure 5+ years on stuff that gets heat cycled a ton is a win. I’m more freaked out about a wrap catching fire from combustible soak of some sort. Not as big an issue if you pay attention to what’s going on with your car on a regular basis. Gotta say though, my recent CV failure would have left a hellscape of highly flammable, sticky petroleum product all over a wrap had I chose to do it.

JoeInOregon Posted December 18, 2021 Share Posted December 18, 2021 I always have wrapped mine on previous cars, I have and continue to use the dei silicone sealer spray, I live in an area with mild ish weather but snow in the Winters. Last car was Audi TT much less of the dp was exposed on that car but mine was still good to go after 8 years when I sold it Sent from my Pixel 3a using Tapatalk Link to comment Share on other sites More sharing options...
busyychild Posted January 1, 2022 Share Posted January 1, 2022 If you have an aftermarket DP I would suggest a downpipe blanket. Easy to install and remove (while still on vehicle) and has the double duty of protecting the axle boot. Link to comment Share on other sites More sharing options...

whitexc Posted January 1, 2022 Share Posted January 1, 2022 (edited) UPS says it should be delivered on Monday.Which did you order Max? This, or something to protect the axle boot is on the list. After further review, I wrapped the upper foot or so of the Cobb DP that appears the be where the blanket will cover (looking at the bellmouth shape). I am thinking the stand off heat shield will better suite my needs plus less fabric to risk fluid contamination....ie boots slinging grease. I have to tackle those inner clamps asap.

SoobyDoobyDoo Posted January 2, 2022 Share Posted January 2, 2022 Max is this what you were referring to? Older but an alternative. Also I think nameless performance also makes something similar… https://legacygt.com/forums/showpost.php?p=4325397&postcount=65 Link to comment Share on other sites More sharing options...
shralp Posted January 2, 2022 Share Posted January 2, 2022 Put one on a few weeks ago after going thru too many melted CV boots over the past few years. Link to comment Share on other sites More sharing options...

Max Capacity Posted January 23, 2022 Author Share Posted January 23, 2022 Finally got around to installing it. I had to get a 4 1/2" clamp so the shield could fit around the top of the catted Invidia Dp. I was able to use the clamp that came in kit just below the bottom of the cat. Sorry, didn't get any bottom up shots. I'm thinking that a 10" long shield would fit better, using the supplied clamps. Or may be a 7" shield would be even better as it would allow all the stand off's to fit over the cat. As now the bottom of the shield is against the bottom of the cat. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

whitexc Posted January 24, 2022 Share Posted January 24, 2022 Wow, I didn't realize the cat on the Invidia pipe was literally looking to melt your axle boot lol. The Cobb pipe has the cat down near the outlet/midpipe connection. Sent from my SM-G996U using Tapatalk Link to comment Share on other sites More sharing options...
Max Capacity Posted January 24, 2022 Author Share Posted January 24, 2022 I'll add, both my cars have the same Invidia Dp, neither have any issues with the axle boot. That's the OEM boot the Spec B came with. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
