Sold

Item Interest

Up for sale is my prototype GR1 Titanium X-pipes that I had got last summer. They were meant to be tested on my car for fitment and design. I have no need for them anymore. I have two systems, one which is Catless and another fitted with 200CEL HFC. They have been test-fitted, seen no road time.

Optimized design and layout - X-Pipe forward placement. Dual resonators for both systems. Catted Version utilizes TWO HI-FLOW High-Grade Titanium 200CEL Cats.
Extreme Sound and Performance. Increase Horsepower and Torque.
GR1 Titanium Grade Material. Professionally TIG Welded.
Catless Version Weight: Roughly 13lbs.

Reason why these are being sold as prototypes because there is a slight modification that needs to be done when installing (any exhaust shop will know what to do). The flange mating the primary section ever so slightly touches the heat shield on the car. This can be easily solved by cutting the flanges off and connecting them together with an exhaust coupling just like when adding test pipes to an OEM exhaust. And the rear section for the x-pipe hanger needs to be raised a tad.

The x-pipe is designed to mate with the OEM exhaust ball flange style fittings. The ball flange is ever so slightly undersized so smaller clamps will be needed, the OEM ones won't tighten all the way. Depending on your aftermarket exhaust some slight modifications might be needed, it might be short by .5cm.
Everything bolts up fine otherwise, the last photo is how it was test fitted on my car with no modifications.

Price reflects the fact that they are prototypes. Sold as-is due to the nature of the prototype.

Toronto (east coast Canada). preferred shipping method is UPS. noticed you in Florida so it would be cheaper than shipping it to Cali.

Would you know how much it would be to ship then to 33409? I am thinking shipping may be too much

It's not as bad as you think. I've shipped a similar system to Cali and it was really reasonable via UPS. PM me your addy and we can go from there.

Need to make space in my garage, I'll cover shipping to anywhere in the US lower 48.

curious as to where you sourced the appropriate clamps. are they included? I am potentially interested.

I'm sure there are plenty of shops in the states to find the appropriate clamps, its harder to find in Canada. If not then you can chop the ball joint ends and weld your own slip on fittings like Akra. Any exhaust shop that deals with titanium or inconel will know exactly what to do.

Pm'ed you but you didn't reply?

[GORDON.M3]

Bump,

I had a few pm's in regards to the fitment.

The flange fitment can be solved by simply chopping the ends and connecting them together with an exhaust coupling.

I don't have time to put more work into these prototypes hence why I am selling them as-is.

Proof of concept: Here is a P65 M3 using a similar design x-pipe for optimal gains and performance.

Willing to accept trades for a muffler/rear section. I'm still trying to get the perfect pitch and willing to play around with different mufflers.

[GORDON.M3]

Bump, spring cleaning.

Hey Gordon, in the video you posted, was that the catted or non catted version? What kind of rear section did you have on?

Catted with the 200HFC. It's a Valved Exhaust, Valves OPEN. Once it's open its practically a straight pipe, so it's not the best rendition of sound. If you still have those wheels I'm willing to trade

[M3@Apex]

Hey Gordon, unfortunately I do not have the wheels anymore but I do have the Active Autowerke test pipes you're looking for. If I can find an X pipe in Canada in the next week or so I would let them go, otherwise they're going on my car. I'm trying to find an X pipe that doesn't require modifications though.

They are simple modifications, I would modify them and sell it as non-prototypes at a greater cost but the shops around me are closed due to COVID19.

I'm selling them for practically the material cost I was charged to have them made.

Titanium isn't cheap.

[GORDON.M3]

Bump.

Catless version left only, Catted one sold locally!

Curious, how would this be like attached to the MPE.

Hollow and loud, high pitched and very exotic like. I've been wanting to pair mine with an MPE but MPE's rarely ever show up in Canada.
