Okay, great question.Thanks.
I'm having troubles figuring out how so much power was gained from essentially stock diameter.
Can you elaborate David? Thanks a bunch.
What would be the difference between your style X pipe and one like this where the exhaust flow crosses eachother? Reason I ask is bc I see alot of exhaust manufactures fab it like yours where it looks more like to pipes connected with a slight bend but the full exhaust flow of each pipe doesn't cross.Okay, great question.
The gains are found in 2 areas. The X-Pipe and Muffler setup.
Below, I've posted pictures of both the OEM X-Pipe as well as our (Borla's) X-Pipe.
You can see that the OEM is really not a true X-Pipe but rather a stamped piece that's not ideal for flow. Also, there's a diameter decrease going into and exiting the X-Pipe and resonator.
The Borla is a true X-Pipe that maximizes flow and maintains the 2.75" diameter throughout.
Our straight through mufflers also outflow the stock muffler configuration.
If you have further questions please let me know.
Can you tell me the overall length of "just" the X pipe please.Okay, great question.

Thanks for the reply David. I'd like to ask a favour if possible (can be done with any phone app) ....Okay, great question.

That's 2 different categories. BMW exhaust are taxed but they also usually use titanium and carbon which drives the cost up.Funny everybody commenting on how expensive this is. Coming from BMW where their axle back only MPE with tips cost 5k plus and most other brands are still 3k plus......this looks like an absolute bargain.
I didn't think I'd be looking at exhausts for this car, but I gotta admit, the extra power is tempting. Probably feels like it revs a little quicker as well. Just worried it might me a little too loud for my taste as the stock exhaust is plenty loud. I've always liked Borla products, but never had one.
If your really bored, check out the prices on the non titanium for a full exhaust on M cars.That's 2 different categories. BMW exhaust are taxed but they also usually use titanium and carbon which drives the cost up.
The comparable GT exhaust to this cost $1400 retail and includes tips. This exhaust is about $700+ more but comes with the dual mode and no tips.
Yea it's a crazy tax on parts just bc of the car. Look at GTR exhausts, those are crazy tooIf your really bored, check out the prices on the non titanium for a full exhaust on M cars.
I agree, it's all relative, but this still isn't bad at all.
I went to Borla and drove my car with LT & ATAK system and I was impressed l could feel the power through the gears sounded amazing like a FPC but (loud)Nice! Any chance you can video it?
I like how you post hp numbers, but the real kind. Will you be selling the X pipe/mid section separately?At the wheels
I'm curious. Did your car have any CELs? I was under the impression longtubes required a tune.I went to Borla and drove my car with LT & ATAK system and I was impressed l could feel the power through the gears sounded amazing like a FPC but (loud)
They are putting the stock headers & cats back in I should have it back in a day or 2 with just the ATAK system installed . I did get a Vid but can't post it until Borla post there vid of the system should be soon.
When I prototyped the ARH long tubes and off road X pipe on stock tune I never had a CEL come onI'm curious. Did your car have any CELs? I was under the impression longtubes required a tune.
If your car did have a CEL, you shouldn't have felt more power.
