You get headers
Xpipe
Side bypass


Not just xpipe


But your saying. There are "ways" to sway a dyno...

 

Look at the dyno posted on the 1st page and the 3rd page, both run #2 values are the same.

 

Nice

 

Headers and side bypass included still won't result in a 12.5% gain on the street IMHO.

Again, I'm not saying anybody "played" with the dyno, or dyno sheet, but I've seen so many weird variations on different dynos (with the same car and mods) that I take numbers with a grain of salt.

Further, and I might be wrong, this set-up doesn't include a tune, correct? Without a tune those numbers are even more unbelievable.

Fabspeed makes great products, and even a 20hp gain would be awesome for the price, so I don't think it is a bad investment in any case.

 

Ok guess no one on here has bought this, well anyone buying other exhausts? would love to hear some feed back about them

 

I was at their shop a PCA visit.

Very impressive machinery and techs. They have a dyno on site. The racks are full of well crafted parts and mil spec projects. There was a McClaren a lambo and lots of p cars - many from 1000s miles away .


The owner gave a talk. It does not appear that they are cooking the books to show increased power results.

My only hesitation was the impact on warranty so I selected a PSE installed by my dealer.

 

Totally agree, and I would never suggest that. Their x-pipe for the e92 M3 is fantastic. I just seen weird dyno results based on so many variables to trust any result that looks too good to be true.

I'd love to check out their facilities!

 

I'm leaning towards the Akra exhaust... I had it on my M3 and the quality is incredible. The exhaust tone is aggressive, but not too much for daily driving... and no drone. The $10K price tag is borderline ridicules though.

 

I'd agree the akrapovic is really nice but I'd also agree the price is CRAZY lol
