Universal exhaust reducer sleeves..do they work?

[njcafe84]

I just picked up the emgo shorties and know that they are an exact fit to the stock header but Ive seen those universal muffler reducer sleeves online and was wondering if they actually work or are just a gimmick.

Anyone have any experiences with these? Should I get them?

yes they work get them if needed ... due to the expansion slot it's a good idea to use some hi-temp rtv silicon to seal the slot eliminating any airleaks
