Batman when you were making your video did you happen to check and see how hot everything got underneath with the exhaust after you made your runs.

I did this to my car before I got any aftermarket parts.

I ran it like this for right at one week. I did worry about fumes, heat, melting things, but I kept checking and everything looked fine..... I also made sure I was always moving.... and even shut it off at stop lights.

The sound is bad azz. It's way racier than my Stillen exhaust, but is about twice as loud (3db). I love the "cackle" when you come off the throttle for shifts or when when you use compression deceleration after downshifts.

If you chop up your rear muffler section and reuse the tips, you could have "custom" exhaust a system built for under $100.

The downsides: 1) It's too loud for everyday use and would be annoying on long drives or taking your boss to lunch. 2) you could easily get ticketed with that sound level if a cop saw you on the throttle. 3) It's still small diameter tubing and you're probably not ganing hp. 4) There's a lot of droning. This may be from exhaust pulses hitting the heat shield over the gas tank and may go away with exahust tips in the appropriate location.

PS. Batman, can you repost the original "muffler delete" video to youtube without the music or post that video to a different site so we can see the full length vid in all its glory?

Thanks,

Phim

Advice on exhaust?

I tried uploading my original vid to youtube, photobucket, myspace, and some other forum and couldn't get audio because of the rights.

It was hot but can't make an accurate calculation as the street is burning hot as well.

Negative sir, don't have any CO smell....i think that comes along when changing the catalytic converters.

Highly doubt it will to much damage. As someone mentioned that the pipes point upwards, i noticed that there is an aluminum shield (silver thing in vid) that takes the heat from the pipes....not saying its OK as i think that shield protects the gas tank from heat but it should be fine for a week or so before i get some tips customized.

Thanks on the feedback, makes me feel that my Z sounds possessed now....especially when downshifting

Have you noticed a drop in fuel economy or other undesirable outcome from the reduced backpressure.

With some new pipes, mounts and tips, this seems to be a cheap mod.

Fuel economy has been affected but i blame it on myself since i've been accelerating more than usual just to hear the exhaust

I plan on getting this cheap set-up done by mid next week. In my meantime i'll wait for a bigger variety in exhausts.

CO is completely odorless, and deadly. I don't recommend you go sniffing your exhaust.

And Semtex is correct, the muffler has nothing to do with emissions.
