I was reading SMG's post before i went to my garage to work on it. Removing the header's bolts are WAY much easier than the headers I did on my m3. i cut the cat off and welded on a straight pipe (kept the stock O2 sensor hole) The installation wasnt that bad at all. Its always fun to cut and weld (not as much doing for friends , tho)
Test drive- I never never never expected the power gain could be so noticeable from the header. after i installed promini's 19% pulley, I lost top end. SS header smooths out the top end SO much more! it made my 19% pulley perfect!
i cant wait to get the superchip done this week!

i forgot to take pics. i will take some when i install mini-madness' Post Cat Signal Conditioner to turn off the CEL.

So all-in-all, how difficult was the installation? Just by looking at mine, it seems fairly easy to do, compared to other cars of the same size.

Back2DTM · Jan 17th, 2005, 05:35 PM

it was not difficult at all. even if i didn't have a welder, i would just take it to a muffler shop for the welding. the rest is easy.

Running it catless perform better? I too have the Supersprint but have haven't put it on yet, I'm waiting for a metalic to arrive. I was thinking runing it Catless too but I was worry about the performance.

Thanks

Back2DTM · Mar 11th, 2005, 04:53 PM

catless should performance better than with cat because no air restriction
. thats why race cars don't have cat.
and i never have to worry about replacing a new cat when it wears out.
the gas smells is heavy sometimes but i am used to it because all my cars are catless.

for example.. this is my RX7 i just built. you can't do this with a cat.

i have video if anyone wanna see it, too.

Is your engine light on? I have ordered the O2 Simulator but I'm not sure if it is going to work.

Back2DTM · Mar 11th, 2005, 05:59 PM

yea the CEL is on the next day. I dont bother to turn it off, tho. I never take my car back to the dealer for service anyway.
