I've held off making this post whilst Akrapovic have been trying to rectify the problem. However it is now at a stage where I believe I should highlight the issue and ask if anybody else is having the same problems.
I had my Akra installed in two parts. The slip-on initially, and at this point it was noted that the exhaust tips were virtually in contact with the rear diffuser. The slightest bump in the road caused the exhaust to chatter up and down on the diffuser. I removed the tips whilst I was waiting for the rest of the Evo system to arrive and hoping that fitting this would help solve the alignment issues. Unfortunately it did not. The UK Akrapovic rep was excellent and attended the dealer to look at the issue. Despite numerous attempts at alignment it could not be resolved. As a result Akrapovic to their credit agreed to replace the rear muffler on the premise that the exit pipes may not have been set correctly.
I returned to (having moved house) a different Akra dealer to have the replacement muffler fitted last Friday. All seemed well after the fitting but on inspection at the weekend, the clearance has been improved by inserting wedges in the rear exhaust rubbers thereby removing the elasticity of the mounting.
I have discovered a nearby shop that specialises in fabricating and mounting race exhausts. I think I will now take the car down to these guys and see what they can do about making some adjustments, either to the exhaust, the hangers on the vehicle or some stiffer polypropylene mounts.
The exhaust sounds excellent and the fabrication looks superb but I am a little frustrated now that having paid the best part of £5000 I do not have an exhaust that is a perfect fit. Having tried two exhausts, is this a UK vehicle issue, a general issue or just an issue with my car?
It is difficult to knock Akrapovic in their response to the problem. It has been suggested that they would even offer a full refund, but that is not really what I want. I would like the marketed product to fit as expected.
Interested to know if anybody has had similar issues and how you overcame them.
