Well we finished up another 4" downpipe(first one was about 1 year ago); except this time it FITS wonderfully and is available in kit-form
Just kinda showing off I suppose, here are some pics:









My personal car is down due to over-revving at the track(downshifting too early).
New setup:
LoveFab Sidewinder GT1 Turbo kit;
GT35R turbo;
4" downpipe and exhaust;
Supertech springs/retainers;
Cometic 2mm headgasket;
14psi of boost on pump gas should get me SOLIDLY into the high 400whp levels, I will be getting this one tuned, I cant handle it myself
Enjoy

havent added the 02 yet its on the list for later today. The kit versions will see a 4" Vband, this one actually is a one-off, so its flange-less at the exhaust junction.

Looks sick.
Wheres the O2 sensor bung?
I'm still pissed I never bought a manifold from you a couple years ago.

actually, reviews(in civics/tegs) are that the 4" downpipes produce LESS heat than the 3" counterparts. My guess is the lack of backpressure leads to more heat evacuation through the exhaust, rather than lingering in the exhaust system.
I ran this setup with a 3" downpipe(with a vented hood) for 3,000 miles and everything was wonderful

how much LESS? ... heat is heat ... when i had my ARC box, that thing was HOT under hood temp ... so i can only imagine how hot its gonna be with that down pipe der ..

well, fuse box is still in-tact, along with all of the wiring looms, etc. The rest of the major heat is evacuated out of the hood vent.
I do have a few customers running with stock hoods without any heat problems
When I run on the track, thatll determine how things hold up; but based on what Ive learned, this will be A-OK.

Nice **** Cody, but I don't think I need that Sidewinder or the 4" DP. But ****, it would be a monster.
Oz: I plan to wrap my manifold and downpipe too when it gets here.

HOLY SHIATE!!!!
You guys aren't worried about melting the vtec soleniod/wiring or spark plug wiring cause it is CLOSE!
Awesome welds, looks really, really good mang.

we have 3,000 miles with the 3" setup, and no melting issues thus far. Some pretty hard driving, and two 700 mile jaunts at one time.
You do have to move some of the Vtec wires, as they DO come awfully close while mounted to the stock bracketry. Other than that, the fuse box has to be moved slightly to allow the downpipe to clear(not the battery though
). Everything else is ok thus far
I have a couple things to finish(jigs) using my car this week, then hopefully I can start taking it apart over the weekend. Its looking rather iffy already though, as I bought a house last week, it REALLY throws things out of proportion with prepping, painting, etc, after work. Takes it right out of ya!

Yes, that is the difference.

which studs do you mean?
I do have to replace two header studs from having manifolds on and off the car all year(20 full torque cycles, at least). Ill try some ARP header studs/bolts if I can get them, or the Honda 12 pt Clutch bolts...those things are BEEF!

ya, same thread; and Ive NEVER had one break, I use them in welding fixtures all of the time, as those things see AMAZING heat cylces. I still have the same 12 bolts from my first few motors I tore apart in-use. 

Hmmm... the heat cycling part makes sense. So you bolt the header/manifold on with the clutch bolts instead of using stud/nuts? I will try it with the kit.
I JUST GOT THE PACKAGE IN!!!! LOVEFAB R0XORS Y0!!!

holy ****, that was fast! UPS
Ya, try it out. Although My studs held up fine till the last manifold install, seriously around the 20th full torque session.
