Correct, Full 3.5" from the downpipes back

mineo77 · 09-30-2011, 09:46 AM

correct, i made the 3rd video with resonated exhaust

Black Sheep · 10-01-2011, 01:28 PM

Let's get a few more signed up.

BrokenVert · 10-01-2011, 01:28 PM

We ever get an answer on whether or not this will fit my car?

Black Sheep · 10-01-2011, 01:34 PM

They have not tried it on a vert yet, I checked with my BMW SA and the coupe and vert share the same system, but clearance might be the issue. The HPF kit comes with spacers to make more room around the brace. So I can't say yes for sure.

BrokenVert · 10-01-2011, 01:42 PM

Well then Ill throw this out there. Im willing to prototype the exhaust on a vert HPF.

evilstib · 10-02-2011, 10:16 AM

I'd be interested, but I would want an exterior sound clip / video of the resonated version.

I'm also wondering how much louder it would be over a stock exhaust with CP-E catless/resonator less midpipes? I get popping / backfiring when the tires break loose and the car cuts power (Not talking downshift gurgling...love that part) and it bothers me...

HPF, can we get a new exterior cam video of the 135i resonated exhaust? From absolute cold startup to driving around...thx!

you will never get a direct comparison of the exhaust. I can tell you this is one of the louder exhaust and the CP-E midpipe to stock set up with OE DP's and OE muffler will sound like a prius compared to this.

The exhaust is being made so the prototype is not in HPF hands to make a video, but the 335i system may be done earlier. You can get a good idea from all the you tube videos, but still any video is off.

Black Sheep · 10-03-2011, 08:51 AM

Here are some vids of the 335i exhaust:

onesick · 10-04-2011, 10:06 PM

I'd be interested as well but I'd also like to know if this would fit a 'vert....

Im willing to do a prototype fit for us vert guys...no one seems to take me seriously though

Black Sheep · 10-07-2011, 10:35 AM

They are taking you seriously, It's just that there is only 1 produced exhaust system at this time, They will try to find a local first and if not I'm sure they will let you test it out for them.

What is the biggest issue with clearance for the exhaust for the 'vert as compared to the coupe? Is it because of the 'vert motor thats located in the trunk... is it a bigger compartment then the normal spare tire of a coupe?

Its because of the extra rear suspension bracing. It can get in the way and cause clunking noises.

evilstib · 10-12-2011, 09:52 PM

I'm tempted to say I'm in, but want an exterior video of either a 135 or 335 driving around...with lots of throttle action!

Black Sheep · 10-14-2011, 07:22 AM

I'm trying to get a go-pro put on the bumper for everyone.

BrokenVert · 10-14-2011, 08:31 AM

So then thats a no to me prototyping a vert fitment then...

HPF Kirk · 10-14-2011, 10:16 AM

Hey Guys! Sorry I havent been in here as much as I would like. We actually have the exhaust with the manufacturer right now so I wont be able to get any new video until we get it back in about 30 days. Tim does have alot of pretty good videos right now. As far as the vert goes, I will do some research and see what some other manufacturers list for it. If it was a Quad Tip Dual Exit exhaust I might be a little worried but it is only single exit. We are having a Dyno Day here on the 22nd of this month so im hoping someone will show up with a 135 Vert so we can take a peak at it. Also if BrokenVert can PM me with your VIN number I can do some digging for you. Let me know if you guys have any questions I can help out with.

BrokenVert · 10-14-2011, 10:21 AM

You got a PM HPF

Black Sheep · 10-14-2011, 10:31 AM

Thanks Kirk!!
