Exhaust for 7MGE

XtreeX · 02-10-2006, 05:14 PM

what about the exhaust? Does the exhaust do that as well? I will probally just get the OBX headers now. Those were my original my plan, but I figure why not go all Pacesetter?! So after hearing that i'll just go OBX headers, get a new head gasket while i'm at it, and replace the exhaust with pacesetter.

After reading these, and all the other supra, forums for a couple years, it seems that the OBX are the choice. You'll have to splice in longer wires for the 02 sensor (no big deal).

I just talked to a guy last week that was building a street racer, and he told me he installed a little box that eliminated the 02 sensor. He said the box simulated the signal of a perfect fuel mixture. It was fairly cheap. He and his dad have built many streetrods, and he has been in the parts business for a long time.

I will try to find out more and let you know.

dude save your moneny, you dont need to spend over 500 bucks on exhaust. all you would have to buy is your header and tip or muffler. I just went to a local exhaust place and had him install my tip and get all new pipe. you get any size you want and the bends arent that bad. i got a complete custom stright pipe exhaust all new and installed for like 60 bucks. just make sure you get a small turbo muffler installed for some back preasure, n/a's need it for low end power. hope this helps, good luck.

I agree with this, if possible go with piping that has mandrel bends. To the original poster of this topic, I know you did some searching, but you probably overlooked this thread. http://www.toyota-supra.info/forums/...ead.php?t=3113 I'll just quote my post from it (topic on headers for 7M-GE).

(RPM x Motor Size)/554,177 = Recommended diameter.

(7,000 x 183.07)/554,177 = 2.31"

I have to disagree with this. NA's do not need back pressure, conversely though, going too big (on an NA) is also bad. The ideal piping size helps with exhaust velocity and efficiency, thereby increasing overall HP. Go too big and you lose that velocity. I recommend you use a universal "straight-through" muffler with at least a 2.5" inlet. Hope this helps.

I agree with the fact that the headers peeled but i haven't seen any rust and its been a while i mean your choice but i don't think its a big deal but i'd suggest if you get one thing, get everything pace setter because i think you get more out of it that way i think.

Well all I am saying is that there is really no protective coating on these headers. When the paint goes then it loses any protection from the elements. It also doesn't hold the heat inside the header and lets it radiate out. That is why I suggested the coating. I think they are good headers, but can be improved.
