Downpipe installation mazdaspeed3

The flexible mesh is to ease installation. I need a new downpipe for my Mazdaspeed 3 the one currently in my car is beginning to fail. Which should I get if all I need is the downpipe it self? It all depends on what's in the car currently.

Shoot us an email with more details and we will be happy to help. Will the 60mm catted downpipe work with cobb catback exhaust for gen 2 mazdaspeed or I need to get the 80mm. If it works with the OEM Downpipe then it would work with the 60mm or the 80mm. Yes you can but there is very little room for install error or you will get an exhaust leak. For anyone reading this I managed to make it work with ease! No exhaust leaks at all. I have a corksport catback exhaust and now i want a long catted downpipe I was wondering what size flange should I get 65mm or 80mm?

I have a cp-e triton catback exhaust system and was wondering what size flange I would need to mate the corksport long catted downpipe to it. The 65mm or the 80mm? If I run the BNR S4 V3 with this downpipe, is it possible that I see any issues with the wastegate flapper making contact with any part of the downpipe? I've seen very mixed things online and can't find consensus anywhere. We have had a few local customers use our downpipe with the BNR with good success.

I want to get the long down pipe with the high flow cat, but I fant afford the CBE right now. What do I need to hook it up to the stock exhaust on the gen 2? Would it be safe to run the catted downpipe, fuel pump internals, and FMIC that I purchase from you guys without a tune?

Or do I need a tune if I am only looking to upgrade these components? The length should be fine, however, I am unsure to which style of flange the CNT has. If it uses a donut gasket then it should not be problematic. I recently purchased the hatless downpipes and racepipe that bolts onto the stock exhaust my question is how many exhaust donuts do I need to order. I know I need one donut for my racepipe but on your instructions for the downpipes it says I need to purchase 2 but don't see were the second one goes only were the first one goes witch is attache to the end of the downpipe.

You will have one for where the race pipe connects to the cat back, and one where upper downpipe connects to the race pipe. Since I am using the stock catback exhaust and am getting the 65mm downpipe if I were to purchase the corksport catback at a later date would I have to repurchase the downpipe or will the 65mm one still bolt up to the corksport catback exhaust?

It will still bolt up. But, it will be wide, skinny, then wide again. If you ever plan to run a full catback exhaust you should just get the 80mm now. Is there a significance in power between the 65mm long catted and 80mm long catted?

Will the 80mm bolt fine with the stock cbe? We rec. Thx for your answer. I plan on purchasing this high flow catted downpipe for my car but im worried about the exhaust smells might be annoying.

When I bought the racepipe, didn't notice no exhaust smell but I mean none but since this dp replaces a high cell cat with a low cell cat, that's why my concern. Hi, On your short Downpipe for mazdaspeed 3 , how many 02 sensors has got your short downpipe?? Which would i need with the Ultimate Racing Catback exhaust, the 65mm or 80mm?

Does it require a tune if I run your high-flow cat? I have your stage II full intake and fuel pump internals. I'm looking to go stage 2. How much power will I lose by mounting this to stock exhaust instead of a full exhaust. I would be using the catted option. You will not lose any power. You should see a major gain with a downpipe installed. Good morning CS. I have 2 questions. Which DP do I need. The 65mm or the 80mm fitment.

And second, do you currently have the one that I would need in stock? The last time I ordered a Catback and it was on back order for 3 months. Thanks guys.

The COBB catback necks down at the catalyst connection so you want the 65mm version. I currently livehave the long catted downpipe on my gen. I just bought a gen2 can i use my old downpipe on my new car? Thanks again great part. The only OTS maps we offer on our website located in the fuel pump internals section.

We also only offer stage 2 maps, so you are required to have a downpipe to use those maps. You are going to want to order a downpipe that has a high flow catalyst in order to pass emissions. Would the non catted downpipe fit the 80mm if I soon bought the race pipe and mid pipe. I'm getting the hpfp and I'm fully stock besides the ap and fuel pump. Well would I have to run a certain stage 1 map or do I go straight to the stage 2.

Any map recommendations. Technically you would want to run a stage II tune with a downpipe, but you are stock intake as well. I would consider running a stage I tune until you can upgrade your intake. Would my engine be okay with the dp of I didn't get the upgraded fuel pump.

We don't recommend running an aftermarket down pipe without upgraded fuel pump internals. The exhaust would be louder overall in volume but the tone should stay the same and there shouldn't be much of an increase with droning.

I'm interested in buying a log catted down pipe and I was wondering, will the 85mm one fit the 3" CPE cat back exhaust system? We have not tested it with the CPE Catback, but you should be able to get it to work, it just might require some tweaking to prevent a leak. If the CPE flange is truly 80mm, then it will fit fine with our 80mm, if it is actually 65mm and then goes to 80mm then you will have more trouble.

Hey guys. On my accessport I am running a stage 1 93 tune. Is there any map that would also support the down pipe to get the most out of it? I have a Mazda 3 will it still fit? Because I saw you guys had the full exhaust system but nothing separately for the This will not fit a Mazda 3, it is only for the Mazdaspeed 3 since you would need a turbo to attach it to.

Why don't you call us or email us so we can help you? The FAQ section is not a great place to try and troubleshoot an issue. The Short Downpipe replaces only the stock downpipe which has a single catalytic converter.

It will bolt to the stock racepipe which has the second catalytic converter. I have a speed3 and I have a ark dts catback exhaust and I was going to buy the catted down pipe and was wondering which flange size would fit. The 65mm will work if you currently have the stock racepipe attached to the catback. The 80mm might work if the flange on the catback is an 80mm flange, but I am not familiar with the Ark DTS catback. I bought the catted DP and hooked it up to the stock exhaust and used the factory donut If you purchase the 3" cat back it will bolt up fine to the catted downpipe you have.

We have several customers that run GT turbos with our downpipe, so it would work fine. Corksport, I have just finished my full Corksport turboback exhaust. Is there any danger to my car being that I do not yet have a Cobb accessport to monitor my engine?

I plan on getting the AP as soon as possible. With the pump upgrade you should be safe but to get the most from the parts get the accessport as soon as you can.

Removal of Stock Downpipe Start out by parking your car in a flat level area and making sure it's completely cooled off before starting. Sometimes things can go faster on older cars if you go through and spray penetrating oil on all the nuts and bolts the night before you start doing the job. With the bolts removed lift the front corner of the cover up and slide it back to release it from the retaining bracket or the rear of the cover.

Next up we're going to start the removal of the top mount intercooler. To do so you'll want to undo the 3 12mm nuts holding it in place, make sure to remove the washers that are on top as well to avoid them falling into the depths of the engine bay. Now remove the spring clamps holding the two hoses on to the BPV using your pliers.

Finally undo the hose clamps from the turbo and throttle body couplers. Lift the top mount free from the car and set it somewhere safe. Be careful as there are metal inserts in the rubber grommets for the intercooler mounting bolts, make sure they don't pop out and end up somewhere inconvenient. Stuff something into the tubes to avoid dropping something into your turbo or engine.

Moving to the back of the engine spray some penetrating oil on the heat shield bolts and allow it to sit so you can get them out easily.
