Out of complete boredom and lack of funds, I decided to "upgrade" my exhaust system using the OEM muffler for stealth and for cost. I purchased a used 98 civic muffler from a dismantler on Alpha street in Irwindale (Amazing source for parts!!!)
and hacked it up.

Step 1: The Victim, $25 from a dismantler



Step 2: The cut off tool I bought from Harbor Freight $9.99



Step 3: The Heatshield removed



Step 4: Honda's muffling



Step 5: Gutted



Step 6: Weld the cover back on (no pics)

This took longer than I thought because the muffler case is very thin and hard to weld even on the lower settings, the torch likes to burn through instead of weld. I left the muffler empty but I would have rather ran a drilled straight pipe through it with some sort of muffler packing. Anyhow, it sounds pretty much like a flowmaster sounds like on a Honda. It does have the G35 sound on deceleration. It probly only added .5-2 hp but it killed some time. Let me know what ya'll think.

 

pics work???

 

Yea work fine. Looks like a clean job to.

 

pics of the final product??

 

haha, that's awesome. I like it!

 

no pics of the final product my camera died, but it looks just like the last picture with the cover welded on. I would have rather ran a straight pipe through it with some kind of muffler packing but I didn't have any of these materials. The main reason I did all this was to see what the OEM muffler looked like inside.

 

you should have put a deflector in there to cancel some of the noise out, but oh well, no worries. as long as you like it.
