Something about Dyno Dynamics brand of dynos being heart-breakers.
Or just downpipe? So I have a stock downpipe with a 2.75" N1 exhaust and am looking to upgrade my DP to a 3" fullrace catted, along with the rear motor mount.
So does the front pipe really make much of a difference? 3" dp to 2.75" exhaust is fine, minimal difference in power like Meesh said. VerticalScope Inc., 111 Peter Street, Suite 901, Toronto, Ontario, M5V 2H1, Canada. ok i just bought a used si 8thgen exhaust. The catalytic converter is the only true restriction in the stock exhaust if you are running the stock turbo. No one has tested it or any exhausts so far as we know. ).

No type of leakage or anything to worry about.
Here goes on my impressions of the downpipe (I ran the cat-less for a couple weeks and now have the high-flow cat version). No! Looks ok but im more pumped about the 3" UR Catless downpipe =).
Our stock turbo is the reason for all this.
Then again it's a crapshoot whether you will be able to get the downpipe to work without a tuner to disable an O2.
Once tuned though i'll have them just turn off the second O2. I have the full race 3 in downpipe catted with my stock exhaust and it fits just fine. Thanks again! - At low revs there is little to no difference in exhaust note (I was surprised by this). stock pipe is enough for the reduced volume. Anthony Chen Well-Known Member.
- The car is more responsive and it is even easier to chirp the tires into 2nd.
- At higher revs, there is a some rasp and it is louder, but only slightly. Discussion in 'Build Threads' started by Anthony Chen, May 9, 2014. In the end the front pipe has only been tested by PRL so far as I know.
As far as I know, you need to use a defouler to pass emissions with any cat-less downpipe.
I think the big boost is on the downpipe and, if you don't upgrade that, then the front pipe/exhaust w/front pipe will net you a slight gain but not the amount you get off the downpipe.
The stock downpipe (cat) has a large opening and goes down to a smaller opening. …

The reason I'm asking is because aFe says this exhaust adds 10 additional whp to a stock Si. The larger diameter front pipe helps with power even if the rest of the pipe going to the muffler is only 2". So has anyone figured out if its worth it to upgrade the front pipe and leave the stock down pipe in place?
Full-Race Honda 9th Gen Civic Si 3" All-Motor Downpipe Features: 304 stainless steel construction; Mandrel bent, large radius bends; Precision TIG welded and purged; CNC'd oxygen sensor bungs "This is a YouTube video of the difference between normal exhaust and the catted downpipe/full exhaust." Or net any gain? I installed a defouler as I ended up throwing a cell. is that the catalytic converter on the front pipe?
The downpipe (cat) and front pipes that replace our stock ones are larger in diameter (2.5" to 3") than the stock one (2").
my question is can i use my old gasket and bolts on the si exhaust? Search titles only; Posted by Member: Separate names with a comma. Sure, you'll make more peak numbers, but the slower exhaust velocity from the larger tubing will, like I said, result in lower gains in the low and mid RPM ranges where you do most of your daily driving.
The person running the dyno indicated that it was the type of dyno in use that caused it to read low.
So, looking at the stock downpipe and front pipe, I notice a few things.
Messages: 5 Location: Panama City, Panama. Also remember that you won't need an aftermarket front pipe if you plan on buying almost any of the exhausts out now as most if not all are shipping with a front pipe as part of the exhaust.

I’ll say this, most bolt ons are not pointless, definitely not pointless but they should not be prioritized. The cat converter is on the downpipe.
By the time it has exited the front pipe, it has cooled sufficiently and the 2" dia. always thought those were under the car at least they were on all my cars i drove in the past.
I've read that the replacing the stock downpipe and frontpipe will allow our Civics to gain horsepower. I think the Si tuned with the stock exhaust without a cat would make basically the same gains as one that’s full bolt ons. It’s tiny.
However, Vits turbo upgrade or big turbo, that’s where the 3 inch downpipe/front pipe and catback exhausts ( and other bolt ons ) will shine the most.
