Lotus Elise Ser 1 – April 2006 – Mark - UK

‘It hangs properly without being forced any particular direction, and all the resonance have gone.

Lotus Elise Ser 1 – September 2005 – Rob - UK

Just thought you'd like a quick update from this season. 
You'll be happy to know that the exhaust handles 200+bhp with no problems at all.
I know the engine I purchased for this season was last dynoed at 190bhp, when it was installed in my car with different throttle bodies it produced around 12bhp more with good torque right through the rev range so very happy with that. 
Plus the added bonus that the max dB didn't exceed 100 all year even with a CRP fitted.

Lotus Elise Ser 1 – November 2004 – RC - UK

Firstly, love the exhaust!
The cars throttle response is much improved over my old JanSpeed Supersports. Bottom end pickup is a lot cleaner and seems to have more torque.
Top end is as improved as the bottom with the car revving around to 7500rpm with hesitation - top job!!!
Just got back from having my car on the rolling road and thought you'd be interested in the results. 
To say I am very impressed would be an understatement! 
Basically the car hasn't changed since my last rolling road session apart from the addition of the QS exhaust. 
The bottom/mid range improvement is fantastic. 
Makes my old JanSpeed look a bit rubbish    :o)
 BHP - Upto a 8bhp increase with an average of 5bhp across the rev range
Torque - Upto 9ft/lbs increase, again with an average of 5ft/lbs across the range, and it has reduced a nasty dip aourn 4000rpm
