My new job pays me nothing so.......I am thinking about making some downpipes to get some extra money and to help out the celica community. I am looking to see how many people would possibly be interested in these. The price for them will be way lower than any other brand out there. $200 is what i think i can make them for. I am going to be making a prototype for some MR2 guy and i figured i can keep making a few more as long as there is interest.
I am going to make them out of 2.5" mandrel bent aluminized steel. "That is supposed to be the best setup for engines under 300whp". Each one will be coated with 1200 degree paint (black or silver option). Stock o2 sensor location will be the same. I will put up some pics after the first one is done but you can see the 3" dp i made for myself a while back on my profile. The design will be really similar but 2.5" pipe will be used this time. So how many of you performance junkies would be interested? I need to see what kind of number i am looking at so i know if i can order parts in bulk to make these things. Also: I can still make the 2.5" midpipes for the 3sgte and 5sfte to compliment this dp mod. I might as well order parts for them at the same time if there is interest there too????  DG Note: thses are not for sale yet ....so i think this is the right location for this post? This post has been edited by DG_Performance: Nov 27, 2004 - 1:29 PM --------------------  |

Right. Be very careful here.
On a 3rd Gen 3SGTE (and I think this applies to a 2nd gen as well), you can actually make the exhaust system too good. With no backpressure at all from a 3" DP mated to a decent performance exhaust the wastegate can sometimes not open in time, and you boost spike. Or boost creep. Best case, you bounce off the FCD. Worst case, you run out of fuel maps, run lean and melt #3 piston. My 3" DP goes on on Thursday. Mated to a full Blitz Spec NUR system. I am concerned about boost creep. Very concerned. I'll let you know what happens. -------------------- JDM ST205
Blitz Spec NUR Exhaust, somewhere over $1000 Needing another one 18000 miles later, bloody annoying. |
