Mega , every thing about it is mega
I fitted it in around 20 mins , no problems with fit I would say it fits every bit as good as the Renault system if not better
The sound is very very nice to me this is how they should have came from new , not to loud and on idle sounds almost stock , makes a very nice noise on up shifts even when driving slow like a small pop/dsg upshift misfire noise
The carbon tips are so well made and so light
The system is self is a work of art welds r as u would expect as good as it gets
If it's good enuf for moto gp bikes it's good enuf for me lol
All in all it's mega lol
