yeah a lift makes it easier, mine doesnt rattle or anyhting either, im not sure why i didnt jsut go under the gas tank, i went under axel i shoulda jsut went under the tank haha
i dont want to go thro the axle cause it seems like to much of a pain in my ass, shit it took for ever to build my downpipe, just for my manifold to crack the following friday
Tchleung, did u have any problems fitting the muffler? I’m thinking of getting the universal Apex’i WS muffler but I’m worried it won’t fit like you set up because of the little space where your muffler is.
hey guys, nice exhausts, i was actually just about to purchase a very slightly used thermal R n D 3" turbo exhaust for the DA for $475 shipped. Its stainless steel and looks like new, u guys think its worth it. BTW, im runnin a turbo b18c swap. LMK thanks
that’s the exhaust I want for my car. Seems like a pretty good deal to me, they are like $630 or so new. I think I’m going to take my thermal I have now (2.25 piping) and cut off the piping and replace it all w 2.5 and no cat. The inlet/outlet on the muffler are 2.5 and the original 2.25 is welded inside of it. I’ll just cut it off and clean up the inlets on the muffler. Then I think it should be fine with the 2.5 inch piping. The g2ic turbo guide says 2.5 should be sufficient to 500hp.
To be hoenst.I don’t think the WS will fit. the physical can looked to be longer, and the oval bigger as well. miesn 14" long cansitor with 5"x8" oval and lengthwise it barely fit, the oval also BARELY fit. if it was too high, it hit the spare tire whll, or the sub frame. You could get away with mounting it lower tho I guess.
How loud are your exhausts???with that big of a piping?
It’s one of the quieter hondas around. Turbo makes such a difference in exhaust tone/note. Until VTEC screams 
How about those that are NA???Becuase I plan on running maybe 3in piping with a buddy club muffler…anyone have that???
If anybody is interested, my 3" exhaust is still in my basement collecting dust. Make me a reasonable offer and its gone. 3" from the cat back to a Magna flow muffler exiting the stock location. Pics are still posted on page 1.
Hey mike what kind of side skirts you got there?

Do you plan on running 3inch piping with a NA setup?

yeah…I have had even answers saying theres nothing wrong but others saying its bad…

It would depend on the power output of the setup to determine what diameter of piping. Correct me if I’m wrong.
A quote here from Dave Stadulis of SMSP Exhausts Relating Flywheel HP to Exhaust Cross-Sectional Area (Diameter) quoted by MichaelDelaney
Here are the numbers for 16g tubing:
OD (in.)…ID (in.)…Area…%Increase…HP…HP/in^2
2.25…2.120…3.53…0%…200…56.66
2.50…2.370…4.41…25%…275…62.34
2.75…2.620…5.39…22%…318…59.00
3.00…2.870…6.47…20%…400…61.83
OD is exhaust outer diameter, ID is inner diameter, Area is tube cross-sectional area, % Increase is increase from the prior OD, HP is flywheel hp, and HP/in^2 is hp per square inch cross-sectional area.
For the 2.75 in. tube, I assumed 59 HP per square inch of flow area, I used Larry’s numbers for the others…you are talking HP at the crank :
2-1/4" for up to 200HP @ the crank, 2-1/2" for 275HP, 2-3/4 for 320HP…
or 60HP (at the crank) per square inch of (cross-sectional) flow area.
This 60HP/in^2 is to get you in the general vicinity. It also is based on the inside diameter of the tubing not the OD (ie. 2" in your example). The ID for 2’ 16g tubing is 1.87" and this will yield a limit of 165 crank HP. 2-1/4" 16g (212 HP), 2-1/2" (265 HP). Now you can get different sized tubing such as 2-1/8" and 2-3/8" to fine tune a vehicle but you can’t get cats and mufflers in those sizes so you should go up a size when building an exhaust in those cases.
The stock ITR exhaust is 2-1/4" but not everywhere. At the B pipe flange the tubing actually necks down to 1.9" OD or 1.75" ID and then opens up to 2-1/4". It again necks down (not as bad) around the flex joint prior to the axle.
