Super Spec Exhaust

Recommended Posts


I've recently had a few issues with a leaky Catalytic Converter. I've manged to get this fixed but I'm still finding the exhaust quite 'boomy'. 


I'm sure I've read somewhere before about bunging up one of the exits of the exhaust (but I can't find the thread).  What did you use to block off one of the pipes?

That would be me 😀    I started off just bunging it up with a tea towel, but eventually graduated to rubber bung off EBay (Item 272283417049) (see below).   But it was mainly to pass the emissions test, I don't think it affects the noise level.

For some reason I missed you when I was collating Superspec owners (Up to 40 now).   I'll PM you with the details.
