Downpipe question

LMT0286 · 01-07-2015, 12:02 PM

I'm getting a cattless dp installed in a few days and I don't have a tune yet on my car. My question is will this mess up my car if it's not tuned? I am eventually tuning it when I get the $. But Prob won't be for a month at least. So will my car be safe to drive? I know it's going to throw a code. I just want to make sure my car won't get destroyed. Thanks

Car won't get destroyed from not being tuned but you will have a pesky check engine light and you won't get any power increase or anything from them until you tune. I would suggest holding off the install until you get the tune so you can take full advantage of the pipes.

So regardless if I get no power it's still beneficial to my car to get it done? Idc about the check engine light

A friend of mine has had catless downpipes on his untuned 335 for around 2 years with no issues besides a CEL. Although, your true power gains from downpipes are shown when there's a tune.

LOL @ not bothering to get this checked out until a few days before install when you know that a tune is at least a month away.

The only reason I'm even asking is cause the place im getting them installed recommended I don't drive my car aggressively till I get the tune. So I figured by them saying that it's bad for my car or something. Now that I no it's not I feel better about getting im them installed
