1.5T civic downpipe

Imo not much gain from a upgraded intercooler on pump gas.


You can get any universal intercooler if you really want one. Just tske the measurement off the stock one. You would need to get charge pipes for it too

Prl is making a intercooler and downpipe. They say the downpipe won't be out until another 2months or so

I haven't checked, but do we have a wideband from the factory?

yes...

I plan on running meth, so I can still use pump gas. Downpipe and intercooler will probably be my last modifications. I gotta stop haha

The downpipe seems too cheap (pricing)

If so, anyone pair that with Hondata yet?

I know Im little late to this thread, but really? my car before this was a 335i and I got a pair of stainless downpipes that are both longer)sure looks like it anyways) than this one for 399 bucks, fit perfect, tons of people run them w/o issue.

anyone hear about downpipes yet?

Attempting to convince vrsf to make one. Initially he sounded like he was in. I haven't talked to him since but the thread doesn't have the interest I thought it would so not sure he'll follow through. I'm guessing modding these won't really take off until the 2k20s when they start to be affordable for some high school kids... I know I've been playing with cars this whole time since high school but I've noticed some friends who used to, just don't care to as much after they "grew-up" lol

What is the size/diameter of the stock cat/downpipe outlet?

I'm pretty sure it's around 2" stock at the outlet

PRL responded to this same question in the other thread 2.25" is the ID of the stock downpipe/cat, then it's 50mm (2") the rest of the way.

So then does the stock DP neck down to 2" at the flange for the front pipe? Not with my car to look myself.

I think @michaelnyden is saying it necks down at the cat. I will try to measure my OEM cat tonight for what it's worth.

Yes, PRL said the outlet ID is 2.25" of the stock cat/downpipe, I have no idea what the inlet is...I believe the front pipe reduces to 50mm, but that can still mate up to the 2.25" outlet of the stock cat/downpipe
