Best xpipe for Akrapovic slip on?

MaverickNemesis · 03-30-2013, 06:48 PM

Been trying to decide for a while which would be best to go with. If anyone can chime in and help me out would be greatly appreciated. Videos are also welcomed. Thanks

Go with the Akra or dinan mid pipe.

Chriskm3 · 03-30-2013, 09:03 PM

Dinan. Or akra

ms372 · 03-30-2013, 09:14 PM

Challenge sport or Gintani with quad resonators

Best answer here. What does best mean?

GT4

I like the tone of my current slip on exhaust but I would like to add an xpipe to it I will do my research into dinan. Thanks guys

Challenge Engineering "Street" will keep the primary Cats and allow passing vehicle inspections. Adds nice sound with Akra slip-on and some mild performance improvement while maintaing primary Cats. http://www.challenge-usa.com/v2/exhaust/bmw/street.htm

I'll throw mine in the mix - Active Autowerke X-Pipe & HFC. Keeps primary Cats but still needs a stage II code for CEL. The secondary cats are replaced with resonators to deal with the drone and rasp. The car has a great howl at low RPMs now.

another option would be doing just test pipes as well, deleting the primary cats on the stock x-pipe.

chris s · 04-09-2013, 12:34 PM

you've basically had every option available thrown out here..lol

I'll be installing challenge sport with akra slip-on in the next week or two. I'm local, you can check it out...

IMG in CT has akra with a full catless (4 resonators) setup...it sounds badass.

he also has a low compression build which helps

yeahhh yeah we know this...

I've got the full Evo and can't imagine it any other way, love the tone. Rekrul posted a thread a while back about his Akra/Dinan x-pipe combo here:

Scroll down to the bottom of the page for his videos. Keep in mind the Dinan pipe is full catless (very stinky) compared to the Akra X-pipe which still has one set of high flow cats. You can still smell it when you back up but is otherwise not an issue.
