Exhaust headers, LS series engines

I reckon mid range and top end are going to be far more usable. It's a formula that has been working well for Ferrari and Lamborghini. They design their cars with smaller capacity multi cylinder engines that rev to buggery and make heaps of mid range and top end. Bottom end grunt is great for towing stuff and getting a heavy car off the mark but my Cobra weighs about 800KG less than a commodore and I don't own a pop top camper.

For the record, I think the pipes on offer look well constructed and are a good price. If I was in the market I would probably buy them.

I guess the difference between discussing the LSX donk in a Cobra and in its usual Holden/HSV is that in the latter, every possible rwkw is attempted to be extracted. However with 800kg shed over a Commodore, Im surprised you guys get any of the neddies to the tarmac. If robbed low down torque is your dilemma, diff gear change may be your friend and keep your current pipes and increase gas velocity through higher revs.

Now I just gotta think of a way of shedding 800kg from my car.
