Is anyone running an S2 K-series elise with Hurricane/de-cat and either Larini Club Sport or EliseParts exhaust.
I'm finally getting round to changing the standard set-up in exchange for pops and bangs now its no longer my daily drive.
I'd love to hear the sound of both in the flesh or any comments from people who may have had something similar in the past.
Has anyone done a comparison between an S2 k-series manifold and an aftermarket 421?
I've got a 2bular 421 on my S1 111S which has given much improved torque over the standard item. The only downside is that I'm sure it's quite a bit noisier than before, but as it was fitted so long ago I can't remember what it was like! I think a lot of the change in sound is probably down to the change in material, from a cast item to tubular stainless. It may not be noisier, just more metallic, if that makes sense.
I've been on a bit of a mission recently to try and reduce noise volumes in the car - it's an age thing I'm pretty sure! So far I've added carpet, put the std airbox back on and fitted a quieter silencer and it has made the car so much more enjoyable (for me) without really taking anything away. The next thing on my list to look at is the manifold.
I've read a few posts over the years that suggest there are two potential improvements that could be made to an S1 on the exhaust side whilst staying pretty standard. The first is to grind out the clag in the standard S1 manifold, the second is to fit the S2 manifold and link pipe.
So, am I right in saying that the standard cast items are quieter than a stainless system? Also, would a cleaned up standard S1 or S2 system be that much different in performance terms to the 421 on an otherwise standard VVC S1?
