This is the resonated exhaust, Tim has catless downpipes so this is truely a straight pipe exhaust.

[lee_fr200]

Any sound clips of the non resonated, and would you deliver to the uk

[Grayson]

I'd love to pick one of these up when they're ready. How are the Cali folks planning on passing emissions?

You don't have the resonated system on your web site yet? I'm interested in that version how much and would you ship to Puerto Rico?

[Black Sheep]

Sounds good, Thanks Kirk

They most likely will not offer a non-resonated version.

The exhaust systems still need to be produced so there will be some wait time but this should definitely speed up the process.

At this time I'm not expecting anyone to pay, I'd just like to get a list of people interested at the discounted price of $1500.

This will be for a resonated mid-pipe version of this exhaust.

The HPF stainless steel exhaust system is one of the highest flowing exhaust systems for the BMW 135i with a massive 3.5" piping and no mufflers. Not only will you pick up power, but your car will weight 40 lbs less than it did with the factory exhaust. This exhaust system bolts directly to the factory cats or aftermarket downpipes. This exhaust system is capable of flowing well over 800rwhp. It is made with 100% USA polished stainless steel with a dual titanium tip. Think running without a muffler sounds loud? Check out the video below and see for yourself.

A Staggering 40 lbs weight savings (OEM Exhaust = 75 lbs, HPF Exhaust = 35 lbs)
100% USA 304 Stainless Steel 3.5" Exhaust
3.5" Fully Adjustable Titanium Tips
Super strong stainless V-Band flanges For easy installation and adjustment along with leak free operation
Fully Polished
100% Mandrel Bends
Flex Section
Rubber Isolated Mounts
Minimal exhaust movement due to triangular mounting method
Aggressive Styling with Large 3.5" Tips
Exotic Exhaust Note


Here are some pictures and sound clips.

I'm Really digging this exhaust I love the sticker on the back too!! Will it come if you buy the exhaust!! jajaja

[bignico_05]

Ok so what the heck is happening with this? R they almost ready to be shipped?

[silverfox]

This wait is painful, hopefully we can get our hands on this by June

[Mr. Nice]

bump for an update, still on track for the end of this month?

[HPF Kirk]

Hey guys! So like I said when we first did all this the countdown really started from when we test fitted and verified the exhaust on Tims car a few weeks ago. From there it was a 8-10 week lead time. Im hoping for sooner since we had some 335i exhaust come in early. So Im hoping that we will have some here by the end of May. I understand this took longer than planned, as can happen with something like this. They are in production and I will see about air freighting over here sooner the people who have helped get this going. If anyone has any questions feel free to call or email me. Thanks again for everyone's patience.

I know we are still waiting for some more Go Pro videos and I will get with Tim to see if he needs a new Go Pro... But a customer with the 335i has made a few videos of his car with the Straight Pipe HPF exhaust as well... Check it out...

If anyone not in on the group buy wants to take my spot shoot me a pm.

[bignico_05]

You know what? I'm willing to give my spot up as well. In fact I'm willing to take a slight loss on it too. So if anyone is interested, pm me.

[mineo77]

Used GoPro camera so sound is not top notch but you get the point. as posted previously, for DD this is great and if you have cats it will be even better. way to go HPF, nailed this one.

[BBBluey]

Should post up a dyno with it too and see if it improves hp. It could help cheer up those that have been deflated by all the shortcomings in this gb.
Sounds nice though.

[mineo77]

We can dyno but my car is pretty modified already so wont yield the best results, esp since its a huge PIA to swap to stock DP's / exhaust and compare to this one, mainly cause I am way too lazy to lug all my OE shit to HPF to do this dyno. With any exhaust it will increase flow and increase HP a bit, but no exhaust is going to really do too much for HP. This exhaust is to supplement other mods so it increases efficiency to all the mods you got.
