This downpipe will require additional ECU tune and is not compatible with the stock tune. Upon shipment of these units we will have a tune specific to this downpipe and it’s combination with any other available Mishimoto products.

With the Cat, would the exhaust note be not as loud?

Thanks guys! Yes, the tunes we will provide will eliminate any CEL with cat-less downpipe use. We will be providing a tune for 91/93 octane, CVT/manual transmission, and with/without our intake.

The catalytic converter will have a very slight muffling effect on sound level, it is not significant. The noise level and tone differences between the two pipes is very slight.

Check out the weights shown below.

Stock Downpipe: 24 lbs.
Mishimoto Downpipe: 18 lbs.

Let me know if you have any additional questions!

Thanks

Great question. We will be supporting this product with several tunes for use with the EcuTek device. Additionally, a protune is also an option for those who do not have this device and would like to install our downpipe.

We have a few videos posted above, showing the sound at idle and during some dyno pulls. We will have additional videos in the near future.

We worked on some initial tuning for the downpipe but we have yet to finalize any of our maps. We will have these prepared once the downpipes are ready to ship out. Our initial results showed some serious gains in torque output. Stay tuned for additional data!

Would this mate with invidia q300? Also would the catless setup pass inspection?

Really interested

Thanks for the interest Leo! As long as the Invidia pipe has the factory-style 2-bolt flange it should mate to our downpipe perfectly. Inspection will vary from state to state, please check the regulations of your local motor vehicle association.

At this time, we do not have finalized plots for our downpipe. These plots are in the works and we are hoping to have them compiled and our tune finalized in the next few weeks.

Man, this so exciting! I'm not sure if I should be this excited about a down pipe, but I am.

I have a few questions for you if you don't mind:

1) Is there any weight difference between the catted pipe and the catless pipe? I see that only one weight is listed. (significant?)

2) Does the catted pipe throw a Check Engine Light? Would not there need to be a second sensor bung after the high-flow cat for the ECU to determine that the cat was functioning properly? The cat on your downpipe seems to be quite a ways downstream. I may be exposing my ignorance of the stock system here, as I have no idea where the stock one is located.

3) Will there be dyno graphs of the catted downpipe as well as the cattless? I'm wondering if there is a whp difference between the two and if so how much.

4) (Semi-off topic)- I'm sure many here are excited about your intake and tune on the EcuTek and will already have them before they get this downpipe. Are you offering free upgraded tunes for this downpipe to customers who have already purchased your Tuning Kit and Intake?

Thanks in advance and keep up the excellent work!

Don't worry, we are just as excited as you are! Questions are certainly welcome, that is what we are here for.

1. Fantastic question. Yes, the catalytic converter will add some weight to the pipe, take a look at the updated specs below.

Stock Downpipe: 24 lbs.
Mishimoto Downpipe (Catless): 18 lbs.
Mishimoto Downpipe (Catted): 21 lbs.

2. Very true, the stock downpipe features a catalytic converter very close to the turbocharger. We have moved the cat further down the pipe for clearance reasons. The tunes we will be providing for both downpipes will eliminate any CEL concerns. The cat will still be functional from an emissions standpoint with this design, but will not be involved in any ECU calculations. As mentioned before, our tunes provided will alleviate any issues with CEL concerns.

3. Yes, we will be providing tunes for both downpipes on a stock vehicle or installed in conjunction with the Mishimoto intake. We will post these plots as soon as the tunes are complete.

4. Another good question here! We offer free tunes for life on all of our power adding products. This means when you upgrade another portion of the vehicle with one of our products, we will provide you with a tune specific to the components you have installed.

Thanks for the inquiry and the comments!

Sorry for the lack of updates on that particular project! We ended up making some minor design changes to the end tanks towards the end of development which has pushed back the release of this project. Our change will provide an improvement over our previous tanks, which we feel is better to change now as opposed to down the line.

At this time, we are anticipating a release date around December. We should have a more concrete date as we get closer to finalizing the production run.

Sorry for the inconvenience!

A big thank you to Adrian N. for being the first on our list for this pre-sale!

Although there are slight differences in the piping between the FXT and WRX, it is certainly possible that our downpipe will be compatible. Unfortunately we have yet to bring in a test vehicle to confirm fitment. Once we are able to do so, we will certainly update this thread!

Thanks

Mishimoto, I think your presale orders will start filling up once you release dyno charts and gain numbers for the J-Pipe. I know I am looking forward to seeing the results. Currently I am saving up for the EcuTek.

Cheers, Joe

Great question! We are planning to run this pre-sale until the product is officially released. We are anticipating this date to be towards the end of October.

Thanks Joe, this is likely very true. We are working towards finalizing our tunes for the downpipe, we should have some data/plots to release in a few weeks.

Ive got to say, im amazed. I just obliterated an 03 gt mustang and all I have got for my15 is the Mishimoto intake. I can't wait to see what the downpipe and intake can do together. Oh yeah, did I mention I havent even installed the intake yet? Lol. I had no idea this car could beat a GT Mustang while stock.

Good to hear! You will be very pleased with the gains after installing our intake, let us know how it goes! Thanks!

This is entirely up to you! If you plan on using EcuTek, we will have tunes specific for any combination of our products. This means, we will have a tune for the intake when you install it. Then, once you install our downpipe we will have a tune for use with the intake and downpipe installed together. Both tunes are completely free with the purchase of our products! More details on our tuning process and results can be found at the link below!
