Hey guys

I recently placed an order for akrapovic's "evolution exhaust system" and im planing to also go with MHP's LT headers. MHP headers come with mids and that made me worry a bit. is that setup even possible?

im no expert at these things and would appreciate any help.

thanks

I think there's a member here with that exact setup - hopefully he'll chime in, but I wouldn't expect there'd be any fitment issues.

The MHP headers/mids bolt up to the factory exhaust rear section. The Akrapovic rear exhaust/muffler hardware AFAIK is designed to mate up to the factory exhaust mid-section as well - so they should mate up with one another also (MHP/Akra).

Should be OK. The MHP setup replaces stock and is completely bolt on. All stock connectors and points remain the same.

Can u get the MHP headers with high flow cats? I live in California so that is a must have

The headers come with mids and will not be compatible with the akra Evo system. However, if you don't install the mid section from the Evo, it will be compatible. If you insist to install the Evo whole system, the headers will need cutting and modification near the stock primary cats area. If you really want the mhp headers, your best bet would be ordering the akra slip on system. If I remember correctly, the diameter of the mph lth is different from the akra Evo diameter, thus apart from cutting the mph headers you will also need an adapter to make everything to work.

The mhp header will connect to stock resonator, and the akra slip on will bolt up to the rear end of the stock resonator.

No, the Evolution setup will not work.
The Akrapovic slip-on will work though since it is a axle back exhaust.

I have the Evolution system and no long tube headers will just bolt on to the Akrapovic Evo system because the Evo system requires one cut after the primary cats before the bend, which it also removes your secondary cats. If you must use the Evolution system, you should only purchase the long tube headers without mids cause the Evo has mids, but you need to have a shop to make a short custom pipe from the long tube to the Evo system.

Ya you can for an addition cost there is cats in the mids. Check out the site.

is it true that the general opinion that Akrapovic's slip on should be quieter than stock axle-back when paired with longtubes? Would there be negations on power output? Thanks

theturkster

It is quieter gives it somewhat of a deeper tone. heres a video of a warm start
as for the negations on power output i hope not

thank you for the help, I am in China and youtube is blocked here so if its possible at all I would appreciate it if you can upload it somewhere else

+1, I just had the slip on installed. It's a bit quieter but with more bass and deeper tone like theturk said.

Trying to decide which LT header to get next; mhp or mbh.
