90 LS, Introduction/New Project

Exhaust from Modified Concepts on ebay, about $130-140:

This appears to be an inexpensive, but decent quality knockoff from either one of a couple different products I have seen and read about on this forum. I ordered the version with the powder coated (black) muffler.

It comes with three sets flange seals, bolts and nuts.

It replaces what must have been an exhaust from a muffler shop, and a Walker muffler added later.

Outside pipe diameter: 60 mm (2-3/8, not 2-1/2 as advertised)
Inside pipe diameter: 58 mm
Material: SS pipes, flanges unknown, probably cast steel, conventional welds
Net weight: about 26-28 lbs
Design: 3-piece (resonator midpipe, axelback muffler w. welded tip, and connecting pipe)

@bryan: I will add more information in the next post incl. fitment on car etc. and a few more pics.

@unified: Did you need different hangers for yours? I ask b/c this one fits a bit snug to the heat shield and under the gas tank!

looks good but looks like it sticks out quite a bit past the bumper

[QUOTE=bryan24207;2276672]looks good but looks like it sticks out quite a bit past the bumper[/QUOTE]Yes, It sticks out past the lower lip, although it is even w. main part of the bumper, so that may be intentional. I did not notice when I was hanging the exhaust, and not a very high priority to fix w. all the other things left to do. Overall I am happy with what I got for $140 shipped. Rest of the pics follow.

Tailpipe and the two hangers closest to the muffler:

Midpipe and hangers (I have since replaced a couple of the hangers to make sure there was more space between the pipes and the floor of the car):

how’s the sound… these ebay exhaust remind me of imitation Tanabe Medallion series…

That may be b/c they are a knockoff of that type design.

I can’t make an objective comment, b/c I am still driving in granny mode. I have some valve noise, and maybe injector click, and the engine is still on the same timing belt it had when it was parked and left to rust 4 yrs ago after two accidents.

Revving it gently from idle to 2-3K, it sounds a bit like a Flowmaster “moderate” style muffler, so a higher note than the heavier Flowmaster mufflers made of 16-gauge aluminized steel, but not raspy like some of the lighter ebay exhausts I have heard. There is a video of a Civic w. the muffler I am thinking of, here:

Until I get the other issues sorted, that is about all I can say.

Did you modify the hanger closest to the tip? Read that a majority of them the angle is* wrong and length is too short.

[QUOTE=TegFan;2276971]Did you modify the hanger closest to the tip? Read that a majority of them the angle to wrong and length is too short.[/QUOTE]You are correct. The angle is poor, and with a stock rubber hanger/isolator, the muffler is too high (too close to the car). You can see it in one of the pictures above. Its not impossible, but not a perfect fit. I replaced the two before and after the muffler with longer hangers. You could just bend the steel hook on the exhaust, but I did not have a vise that is strong enough. Or, cut it off and weld it back on at a better angle.

Getting around to what’s going on in the engine bay now. Did not find any signs of obvious oil or fluid leaks, vacuum lines all seem intact, although old, spark plug wire ends are clean and resistance is all in spec. Engine sounds and idles a bit better at around 750 with new plugs, but still in need of a good tuneup.

How it looked yesterday after some dusting and a quick wash, all stock, or at least replaced with oem parts (AFAIK) when it was daily driven:

Still hoping to drive the car today, with any luck a bit further than around the block, then tackle the leaks at the tail lights.

First snow today, following more rain yesterday, so I decided to go after the hatch leaks. Found the roof drains and cleaned the 22 years of dirt out. Tail light seals were dried out (expected that) and actually came apart when the lights were removed (that took some time to clean up).

I had originally wanted to make my own seals, but time just was not on my side, so i used the Honda replacements, even though diy seals look eminently doable. The seals are cut from a flat sheet, and take on the shape of the tail light only when compressed between the metal and the light.

guessing at the shape of the seal from the shape of the headlight may be difficult, but measuring the flat seal before it is installed, not so much.

The seals are $26 each from the dealer, or about $20 plus shipping online.

Good lookin out on the measurements and part numbers… I archived them on my phone for later use. Thankya!

Well, it is official. This car has been rescued from being parted out, with a few “donations” from integras that were not as lucky and gave their life in the service of their owners… (insert moment of silence)

And more important in no small part thanks to members of this forum whose posts I have scoured for information over the last few weeks. Since this is probably the only thanks you will ever get (chuckle) - if you are reading this, and you have taken your time to post information for those relatively new to this car, or just plain clueless - THANK YOU!

Next on the agenda, a good tuneup, and all the normal maintenance items I did not want to spend money on until I was sure the car was out of surgery, and off the critical list.

would be a fun thread to watch

subscribed i have to search these seals
