Shaddyy · 02-15-2019, 11:09 AM

is it safe to drive catless without a tune? and is it safe to drive with increased emission?
current test pipes, secondary cat delete, and acm muffler mod

Yes safe to drive but more of an annoyance seeing the "increased emissions" light take over your idrive and the check engine light on

Yea its fine to run without one, but you'll extract more power from a tune and test pipes.

A lot of guys run test pipes and no tune. If the engine light doesn't bother you go for it.

I ran test pipes and cat delete without a tune for a couple months with no issues. Just the "increased emissions" on all the time.

running catless with no tune will give you garbage gas mileage..

Yeah and the car isn’t as smooth.

Definitely better to pair it with a proper tune.

That said, the biggest drawback in our eyes is not being altered if there is another existing issue, as the presence of the service engine soon light is normally disregarded from the exhaust change. We've had customers come in for a tune that we're driving Catless without one for awhile and found other issues that could have been addressed if the car was properly tuned.

We have some specials going on, feel free to PM us
