Update on this exhaust:

I have now had the exhaust installed for close to 6 months and I like it even more now than 6 months ago.

I don't know what it is but if you read my initial review I had hoped the exhaust was a little bit quieter but now I think it sounds absolutly perfect. There is absolutly no drone even with my hfc.
This has become one of my favorite mods and highly recommend this exhaust!

 

I've had mine for a month and fully agree with the above ^^
