C63
<div class="bbWrapper">Just had the centre baffle taken out of my c63 and replaced with a straight through pipe. Sounds wonderful and cost £110. Real growl at takeaway but no drone at cruising speed. Lots of nice burps and bangs on change down too.<br /> <br /> Done by Tony Banks exhausts in Leeds. Gave the original section back to me and said they would refit if any future owner wanted to return it to stock.<br /> <br /> Left cats untouched. Whole thing took about an hour.<br /> <br /> Used Tony before when i had an XJR and he did a cracking job then as well.</div>
 
<div class="bbWrapper">+1 for Tony - used him for years - excellent workmanship</div>
 
<div class="bbWrapper">I assume that means the resonator box? In answer to the question about telling more - on the C63 exhaust you have downpipes, then primary cats, bit of pipe, then the secondary cats, tiny bit of pipe, then a resonator box which leads to the back box assembly.<br /> <br /> I have had my secondary cats deleted but left the resonator box in place - sounds awesome but will write up a more detailed review once I have lived with it for a few more days and had a dyno run done to ensure i have not lost any ponies..</div>
 
<div class="bbWrapper">Cool thanks. Is it switchable back for MOT time? How will it affect the emissions removing the secondary cats?</div>
 
<div class="bbWrapper">Apparently will still pass emissions after sec cat delete. It is reversible in so far as they cut the pipe to take them out, then weld new pipe in, so they said they can reverse by removing and re-welding if needed.</div>
 
<div class="bbWrapper">Ahh, ok, would rather something that does not need cutting and welding, but maybe clamping.<br /> <br /> I see you are in Surrey, i'm Hants/Surrey border. Maybe arrange a time to listen to yours and see if it convinces me....??</div>
 
<div class="bbWrapper">The clamps tend to leak though.</div>
 
<div class="bbWrapper">Any videos please as they are just round corner from me</div>
 
<div class="bbWrapper">Yes it's the resonator box. Basically a box full of baffles and steel wool. Car sounds wonderful without it.</div>
