If any of you are looking for an exhaust for S4 or S5 B8/8.5
The only one with no drone at 70mph is the Scorpion, should still be 10% available just quote "no drone 10%"
This is the test and review I did, it's going in the owners club newsletter and on a few Audi forums. This may be useful to some here before you waste money and find out you can not live with the drone.
I had the infinity exhaust but it was just a little to loud for my toddler, it settled in nice and if I were not doing school runs with a whiny toddler it would have been fine.
The quality was excellent, the tone was strong and deep, sounded great on overrun and on hard throttle. There was a slight drone at around 2.5k under load, as wales is all vallys, it's under load 50% of its life. The drone was not excessive but in a 4year olds world it interrupted the frozen watching on DVD it's the end of the world.
I returned to infinity and they did not think they could get it to a level that would not drown out frozen a little. So we returned it to stock, frozen was once again returned to perfect clarity, o the joy !
Round up..... Beefy sound, great build quality and fit, slight drone at 2.5k 8/10
I was talking to a guy who had bought an S4 exhaust from eBay, he fitted it and removed it. I phoned him and asked if he had returned it yet, he said he had not so a plan was hatched. I was going to try and review a few a few exhausts and post the results here.
I popped to his house and picked it up, drove straight to a friends garage and had it fitted.
The EBay Specail
This is a no name eBay special, straight out the gate it looks cheap and somewhat flimsy. Does not look worth its £400 price tag, fitting is a nightmare, nothing fits well, it has to be muscled on.
As soon as its started its bad, sounds like it's touching the underside rattling, buzzing and knocking. I drove it up the road and o dear, it sounded bad, like every 17year olds nova with flick on bits. Did not sound beefy like the infinity, just sounded broken !
