2 Best Fiesta ST Catless Dp Comparison.

[Rcs347]

I am set on the cpe catback exhaust but was looking for the best catless dp to go with it. I am torn between the full 3 inch cpe dp and the enhance performance dp that is very unique starting out at a 3.5 and gradually tapering down to a 3 inch. Help me choose. I provided a link for both below.

Neither! You're not going to see a huge difference in power between cat and no cat but you'll pollute 100% of the time without one. Be an adult...show some integrity and responsibility. I know...my comment will fall on deaf ears and be attacked by all those, "drive a Prius" idiots. Higher performance is not mutually exclusive with still keeping emissions in check. That's reality.

A catless car in the state of New York that's a great idea not.

best is a matter of opinion
We offer the cp-e downpipes and are truly well made

Just as our opinion
The "best" downpipe would surely be the Peron super stock 3.5"
We carry the Peron line but never listed this item due to cost over the more popular options such as our house brand DP's

This downpipe is Just over $400 with shipping

I Have Rons DP that is catted....definitely helps with the Raw fuel smell you can get with non-catted Versions.....Whooshs Dps are all good choices even the Peron pipe that Ron has for $400 is a great deal. Keep in mind of emissions if your state requires testing also.....FYI.

somebody correct me if wrong, but my research so far says a downpipe upgrade is mostly pointless until you go bigger turbo with aux fuel. again, this is only from my reading on here.

That's what Mishimoto found when developing they're downpipe.
