If you want an oval its supersprint or blueflame really that do the best as far as i have read

Milltek do not do an oval for the LC just the LCR

I have a blueflame and its louder than probably i would like it to be, I hear that the supersprint isnt too loud.

If you're hapy to go OEM i'd go milltek. Well tested, good performance and not too loud just a nicer sound
 
right, a little update on this, i'm now seriously desperate for an exhaust, all i can hear is the back box banging on the rear axle, it sounds like a right shed. anyway i can't get a Milltek fitted anywhere near me until a few days short of August, so, i've decided to be a test dummy for you all and i'm getting one fitted at the custom place i've mentioned, they have a great reputation, i've been there before and had good experiences, they are doing me a cat back 2.5" system with any tail pipe for £280 fitted. here is the website for you to look at clicky here!!
I know some of you won't agree with this but i'll post pics in my readers ride and make a couple of updates as the exhaust gunks itself up on noise, performance etc...
