I have also done the throttle body bypass. Not sure what difference it makes, but it is easy.
Longer rear bolts so its lowered to be even with front, this one is also really easy.

I also have the pace setter ceramic coated shorty headers, x pipe, and borla exhaust. I also removed the air injection when I did the headers.

I bought a 3" x pipe from a company called flowmonster... I can't seem to find them anymore.

I've been considering doing a 4.10 gear too, then get it tuned so I can get the air code deleted.

Borla cat back exhaust

Replaced SPEC flywheel/clutch with OEM flywheel/clutch. (long story)

Replaced blue tag ZF with black tag ZF transmission. (same story)

Several different sets of wheels/tires. Now has original looking wheels on it although they are actually 17" x 9" Camaro SS wheels with the Collector Edition center caps.

Windows have dark tint.



?? I suspect mine has a hot cam or something similar, but I did not put it in. It just runs better than expected, so who knows ???

396 with seriously ported stock heads (they flow about like AFR 195 Comps), a Comp cam with two different small XFI lobes on 108* centers, ported intake, Hooker Super Comp headers with custom 3" duals, aftermarket hi-flow cats (downstream O2 sensors deleted), Fidanza aluminum 13lb flywheel and NOS Chevy racing clutch, lots of suspension mods, four different wheel/tire setups.

Post an idle vid. I'm sure we'll be able to tell if it's cammed.

With most aftermarket cams I'd agree. But if he thinks it just has a hot cam in it, I don't think there's a big enough difference between it and an OE LT4 cam to make it sound any different.

Hotcam could only dream of sounding like that.

It all depends what exhaust setup you have. All the hot cam vids on youtube are people with tame exhausts.

Since I bought the car in 2000 its had a few different setups from all boltons to the current setup, 397ci, ported original heads, DRM longtubes, 700R4. Going to freshin it up over the winter, do some more work to the heads, little more cam. Redoing the trans now since it decided to depart from the motor last time out.

I don't think any exhaust setup can make a non-lopey cam have a lope like the one in that video!

Koni shocks, EBC ceramic pads, HRE (wider) wheels, Hella 100/80W H4 lights, Hooker Aerochamber mufflers.
Probably the best modifications were the MOMO steering wheel and Corbeau seats.

Anyone have muffler pipe eliminators? Is it pretty loud? Is it worth getting?

I've got eliminators on both my cars.. it's not too loud, but it can be if you remove the resonator as well.. and even louder of you do away with the cats.

just muffler eliminators isn't too "loud". I have a exhaust video of what it sounds like.. let me see if I can find it.
