Hey guys, I'm new to this board and I'd like your thoughts and opinions on which 02 housing downpipe, external dump to get. STM OR MAP? They're both around the same price, but, which one is more durable, perfect fit, etc?

 

Map has good service and reply back to messages same day on fb, I just like stm more bc there cars make numbers in the game but both are good company's

 

yea, STM does produce good numbers on their cars. I tried to look up the downpipe 02 dump on youtube for STM, but, couldn't come across anything. Only MAP, that's why i made this thread. If anyone got some insight on both companies, please share your experience with the item or company. Thank you

 

There are plenty of options out there. Muse O2 dump from VR Speed Factory is priced very well.

 

Can vouch for the Muse 02 dump. Been running it on my Evo IX track car for a couple years now with no issues

 

Just put the STM O2 open dump/down pipe on my car and it fits awesome. I pretty much buy everything from those guys, OEM or aftermarket parts. Nothing aganist MAP, I just started using STM one day because they are close to me and I've never had a bad expirence.... So I stick with what works for me

 

I'm a STM guy myself, but i purchased the map 02 eliminator down pipe from map because STM didn't start producing them. But I have seen both of them in person. You're fine which ever way you go.

 

sounds great guys. Thanks for the input, much appreciated. I'll also check out the Muse. I'm still learning about the evo, and other companies that offer parts for it. Coming from an 2012 wrx, 06 STi, and an 05 s2000 ap2, my evo just outweighs those cars to my liking by far.

 

would any downpipe fit the muse? For those who have the muse?

 

As long as it's a direct replacement for the OEM part then it'll fit

 

I noticed with the MAP and STM, it's a 3" downpipe w/ O2 dump. Now, with the Muse O2 housing, it says a 2.5" would it be the same as STM and MAP if I buy a 3" downpipe separately and paired it with the Muse O2 housing? Or is the STM and MAP a 3" housing?

 

It wouldn't be the same. The MAP eliminator downpipe is 3" all the back, from the 02 housing to the testpipe/cat. The Muse 02 dump is a 2.5" pipe that connects to a 3" downpipe via the donut gasket.

 

Yea that's what I figured. Well, it's either MAP or STM for me, for sure. Probably gonna go with STM

 

Both are good companies with good quality. I think Austin at STM goes the extra mile with prep work and technique and has a lot of pride in his work. That alone would steer me towards them.

 

Yea, it really comes down to preference at this point. Probably gonna go with STM 'cause their evo's that they've built backs up their reputation. Plus your guys' input. Much appreciated y'all. Looking forward to learning more about the evo community as well.
