Anyone run a WS2 cat less?

[Taco]

I wouldnt mind my ws2 being just a little bit louder, I was thinking about ditching the cat. Anyone ran this combo? Just curious on how it sounds, I know some cat less exhaust setups sound like crap

Apparently this GSR has a 4-2-1 header, test pipe and a WS2.

Hmm... Not sure if I like that or not. Thanks

IMHO removing the cat on NA 4cyl engines sounds terrible.
An aftermarket header would add volume.

Idk. My crx sounded pretty good with an eBay header, gutted cat, and obx catback

I don't run the WS2, but I do run cat-less. Can't say I hate it or love it. It is what it is. Very loud and obnoxious.

would a tune be necessary if OP opted to change the oem header to aftermarket?

well it would flow more air so technically the air/fuel ratio would be affected. But it depends on how much AFR is affected. Usually its not enough to make it dangerous to run without a retune but its not making the most power capable either.

While we are on that subject, what's my options for tuning. Car is a 99 gsr. Pretty stock, just a few bolt ons

word, thank for the insight.
