Best Downpipes
Hi Guys,
There's quite a few options out there for catless downpipes. Is there any out there that are a real cut above the rest? Can titanium be used for downpipes? Which company makes the best? M5BMW |

I'd just gut your stock downpipes. Or buy an OEM set off eBay for like $200 and knock the cats out (so you still have your original pipes to put back on).
Sounds awesome and a lot cheaper, better fitment. |

When it comes down to it they are all pretty much the same. Some have better welds than others. I would advise wrapping them or ceramic coating, cheap to do before install and helps prevent heat soak through DP's.

Would gutting the stock cats cause issues if the CEL light stays on? Someone mentioned the ECU might cut power? I'm down to gut the stock downpipes but want to make sure leaving the light on won't be a problem |

I don't believe aftermarket Dps will offer a HP advantage over gutted OEM.

You believe aftermarket dps will offer 5-10 more hp over gutted OEM dps? How do you figure this?
