Don't GIVE UP! I THINK you should collect the runners under the car, not as they pass the steering column. This is a common type of header in hot rods.

This will allow your shop to arrange the runners on the driver's side to get around the steering column, THEN collect under the car.

In other words, the runners can be arranged in ANY LAYOUT- they can be a long, curved row, 3x1, etc as they pass the pinch point. It can be done with very little, if any impact on power.

Frankly I am surprised your shop didn't see this coming. This notorious pinch point is THE ONLY reason long tube headers are not made for this car.

Yes it's tight under there but there is room for the whole thing with a shop like this and the engine out. Make sure the other side collects at the same location across the car.

You can do it!

 

You're right, I also believe the problem should've been foreseen. I certainly knew about the pinch point, but I think they bit off more than they could chew on the offer. Great guys, great shop, and a lot of knowledge, but the offer ended up being more costly (to them) than they were willing to absorb. From a business standpoint, reluctantly, understood. The next offer was to install a set of Kleemann long tubes, labor free. I ordered the Kleemann's and had them installed just before the weekend.

Here are the dyno results:



There are some problems, and I have some questions for your guys who know better than I do, I'll address them in another thread.

 

What mods do you have done at the time of that dyno?

I just ran mine today at 3900' elevation with Kleemann headers/downpipes, Kleemann ECU tune, primary cat delete, resonator delete, x-pipe, and drop in K&N's. Max HP 313.51, and max torque 323.88. My secondary cats may be partially clogged as noted by the dyno operator with a slight ammonia smell after each hard pull. So now I may be looking for a set of 2.5" high flow cats. The dyno operator offered to let me re-run the car if I get the cats replaced, just need to find a good set, and a good welder to install them.

Take care.

 

Hey Tanderso, my mods are listed in my signature, I think I have just about everything you have except the ECU Tune, and I have deleted my secondary cats. My problem was the MAF, it wasn't installed until today, and now I'm anxious to get it back on the dyno- it's like a new car! I started it immediately after installing the new MAF and without the air filter cover and it made a sound I wasn't familiar with before now. I'm 100% positive my dyno numbers will increase. I addressed my power problems in the other thread:

That makes more sense benzokirk, my guess is a big jump across the board with the issues fixed. Nice car for sure.
