Exhaust size & bhp.

Nothing wrong with the system and i actually like how it sounds.
 
The car was initially built to drag race but now decided i\'d prefer to do some track days instead.
With castle coombe being my nearest track (still 100 miles away) and there noise levels being 100db im just above them.
So somehow ive got to reduce noise levels a bit so figured a slightly bigger mid box and a dolphin shaped rear tip should hopefully solve it, but im open to suggestions as the days of being able to throw money at the car have im afraid long gone.

Ah, ok, thanks!

Well i did Combe recently and hit 97db first static and then 99 after i got black flagged so around the same ish (3" system).

I would try a repack first with good quality packing, i would imagine the stuff in the magnaflows is pretty rubbish. If you go here http://www.thermalvelocity.co.uk/calc/calculator2.html for acoustafil you can enter your silencer dimensions and it tells you exactly how much to use, very handy! Would be very interesting too see the results, p.s acoutsfil expands with heat so gets better after a few runs!

have you used this stuff yourself with good results?

Ive not tried anything else apart from it, it does get some good reviews and was highly recommended on the threads i read, do a google search and have a read.

Could you confirm your silencer sizes please Lee, from magnaflow i mean. Thanks

I have the one you linked as my midbox and the 24" round one as my rear http://www.magnaflowstainlesssteelexhausts.com/mufflers/polished-universal-mufflers-silencers/14772-polished-mirror-finish-round-stainless-steel-muffler.html

Let me know how you get on if you go the repack route buddy.
