ok well here goes;
My dad and i have been wanting a correct 4-1 header for our 7-afe for a long time, we have finally gotten around to making one. We used the plate that attaches to the engine from a Aerospeed header, so yes that was salvaged for parts. Then we had a shop bend up some pipes, all equal length. To be precise they are 37" long and they are calculated to be the length for the best performance gain at peak power, so then it falls right back into the peak torque and off you go again. So anyways, after about 3 weeks of work here is the result. All the welding except for the tacks in the before pictures was done by me, and the wrapping of the system was done by my father and I. The collector was purchased from Pegasus Motorsports, and the rest of the pieces were purchased or salvaged from our old 4-2-1 headers. Sorry for the number of pictures but i figured people would like to see it in detail from many angles. I am hopefully going to finish installing it on mthe car this weekend, so if i get a hold of a camera with sound ill try to take a sound clip of it with just the headers, cuse i know it sounded badass before it was welded.

well you could have just thrown a 10-15 degree bend and cleared everything, its a shame those are crushbends tho. it'd be nice if you made a 2nd version with mandrel bend stainless steel.
honestly, the ebay header isnt bad at all, it looks like you have one on your car (in the signature) infact! its the same layout as stock 4age and 7afe headers are in other countries. same cylinder matching and same runner length, just stainless steel. same as the obx, megan, and several other 'brands', just the ebay ones cost $100 instead of $300. with my ebay header i have a NICE pull above 3500 rpm, 4000 rpm is great, and it pulls the whole way till it shifts, then i'm back around 4000 rpm with more pull once again.

Tiag tiag los? I didn't know a header makes that much of a difference. I was gonna stick with stock for a while but then again there is that major restriction on exhaust flow. Just better throttle response? How about the gains? Do you feel any improvement in power besides response? Also, I was gonna go after 4-1 headers instead of 4-2-1 becuz of the exhaust flows better. -------------------- ![]() |
