Mike's Customs Downpipes with flex section

jackkk · 05-21-2015, 05:32 AM

Hi, just got a new downpipes. Will install next week and post the video.
Here are some photos and iphone video.
The car now sounds great, the throttle response is much better and the car feels easier to go.
I did Eisenmann Delete-R anf BMC filters.

If you are interesting in this product, PM me.
PS It is possible to make a group buy with the discount (10 units minimum) - it will be $800+shipping.

Where are you and how much are they? They look good.

edwinm3 · 05-21-2015, 03:59 PM

Looking good and great price wow, curious to see what others have to say about pricing theirs so high

VCP · 05-21-2015, 04:09 PM

I love it! Looks like my 2 stroke MX pipe, badass!

Be interested if they can make a high flow cat version (200 cpi) with flex section.

I'm slightly concerned about how fast these DPs neck-down. I'd prefer them to stay as large as possible for as long as possible. This may or may not affect performance, however. It is hard to say.

That being said, these look like quality pieces.

Looks great. Ceramic coating option?

No ceramic coating.

A little help to speed up exhaust gases on their way out wouldnt hurt.

Too fast of a neck down, too soon post-turbo, can cause back pressure issues, depending on the situation.

Also, the larger diameter piping is unequal length, that may or may not be by design. I've never been involved in DP R&D on the S55, so I can't say for sure on this particular setup/platform.

First video from the iphone.

Question from somebody that can answer regarding these DPs.

Is the inner diameter of the V-Band and pipe after the turbine housing outlet 3.25 inch, necking down to 3 inch?

Hopefully somebody can answer.

I think that the turbine housing is 3 inch and it's going to 2.5 inch to link the 2.5 catback.
