Is there supposed to be a gas smell after installing? Had mine on for a month and at idle the vents just push in air from the engine bay and it smells and gives me a headache
A lot of write-ups mention removing three heat shields. Looks like you only had to remove two? I'm assuming the third heat to remove would be the one on the underside of the exhaust manifold.
Hey I just installed my DP by way of your instructions on the video. Everything works grear. Except now I'm getting check engine lights about my front and rear O2 sensor being negative currant or something. My question is can I run my car without them safely or without hurting my engine?
If you have an aftermarket downpipe then you're basically guaranteed to get a CEL after install so that's perfectly normal. You need to have an Accessport to get rid of the CEL because your ECU doesn't know you upgraded your downpipe. Btw I hope you have upgraded internals lol
On mazdas u nees to upgrade the fuel pump. To a high output one. Because u care isnworking harder. Thanks ***** i forgot to respond. It was actually a loose cable connection to the oxygen senor. It workes great.
If I just install the Cobb downpipe with the manufacture exhaust with the upgraded high fuel pressure pump internals do I go to stage 2 on my accessport? Or I have to upgrade the exhaust also to go to stage 2?
Stage 1 is just the tune, Stage 1+ is intake and tune (hpfp suggested but not required), then Stage 2 is the Tune, intake, HPFP, and then the dp. Going by stages is a subaru thing tho lol
Do you guys happen to know if I should install the 3.5map sensor with the downpipe or just when I’m going with the next stage turbo? I still have the stock turbo
Could just be leftover PB Blaster or WD40 on the exhaust. Or you're suffering the fated "Smoking Turbo", which really commonly shows after you start modifying the exhaust. Try running a 5w40 weight full synthetic oil (like Rotella T6), and see if your problem doesn't get a little bit better.
I always run Rotella T6, i found out the issue is that the downpipe has oils left on it from the manufacturer and the smoke is the oils being burned off.
trying to get the secondary o2 sensor electrical plug out but its a fucking country mile up inside the car and i dont know how the actual clip works... fuck this *rant*
Slip is 100% correct. I spent over $600 replacing my fuel pump bc i did not do HPFP internals, .. i then spent another $350 for the Internals .. Don't be a tool. spend!!
@@zakkiller223 to replace the intank fuel pump, parts and labor. I killed the fuel pump from overworking it when i installed the DP and not the internals with it.
Looks like a nightmare. So many things to fuck up and spend even more money on. I look forward to none of this with my cpe downpipe. I might just have to wait to pay someone
I made one attempt and was unable to capture the same clarity as cobbtuning themselves. This is their sound clip COBB Tuning - MAZDASPEED3 Gen 2 Version 2 Catback Exhaust
These videos always give me so much confidence and then I get under the car and I’m scared shitless
Dude, biggest fact ever. I'm tackling the exhaust manifold, turbo, and DP now and it's scary. Slowly getting there though!
about to do this a second time on a second car and here i am watching again... great video man! Thank you so much!!!
Thank you for this video. Definitely made it so much easier to replace a bad O2 sensor 🙂
Just did a long atp catless dp install and wow was it a PITA lol
I have the same DP, trying to mate it to my Cobb 3" SS catback. Lining it up is a huge PITA. Any advice?
two questions: did the down pipe set a code? and could heat wrap be used as a suitable replacement for the heat shield?
should not get engine codes if its tuned for it
Is there supposed to be a gas smell after installing? Had mine on for a month and at idle the vents just push in air from the engine bay and it smells and gives me a headache
if it's catless it will smell.
the reason I got a 2013 MSP 3 with a cobb access port and cork sport exhaust I haven't been able to lift it up to really look at everything
Your car is goals

Only had to remove two
Does this 3 inch down pipe plug right into my stock exhaust
Cobb instructions say use the Primary O2 sensor into the cast bung. You put it in the welded bung. Now I'm confused. Please explain?
Does it fit on a Mazda 3 2.5l ?
how much hp do u gain from this just rough guess
All that and no sound clip?

+SimplyCRehZ what do you mean by upgraded internals and why is it necessary for a downpipe...?

good work
whats up evan , I know your watching this video lol
So do you remove the catalytic converter ?
nery1011 this downpipe is catted, it removes/replaces secondary cat though
eh
If I just install the Cobb downpipe with the manufacture exhaust with the upgraded high fuel pressure pump internals do I go to stage 2 on my accessport? Or I have to upgrade the exhaust also to go to stage 2?
Stage 2 with or without exhaust. Always stage 2 with downpipe , hpfp , intake and turbo inlet hose
MikeyandS2 I wasn’t sure
Stage 1 is just the tune, Stage 1+ is intake and tune (hpfp suggested but not required), then Stage 2 is the Tune, intake, HPFP, and then the dp. Going by stages is a subaru thing tho lol

Is COBB better than CorkSport?
In my opinion they're both very good.
Daniel Hernandez I thought so... thanks
Has anyone encountered smoking after installing everything? My car began to smoke pretty badly out of the engine bay right after it was turned on

Don't u need internals the ap to run the dp
Yes hpfp internals are required to run a downpipe safely.

Duralast tool ? is this a joke? But really good vid Cobb!!!
Nice work :) Make a sound video :D

Twist and Maneuver the Downpipe out…. But you don’t show us how you did it. Thanks for nothing
