That was my gripe with the thorleys as there not much better. I've been wanting to put on another true collector to weld in but that's another day another story . here's the pics of dt's for comparison

The crossover might not interfere with the throttle body as much, but overall they look smaller. Probably the crap calspeed was talking about "making."
They would probably accept like a 350 offer. Maybe less.

You show me one stock ls4 that these headers are a direct bolt on no modification required item. Talk about false advertising. You tell me how I am supposed to connect those headers to my existing exhaust system without doing some welding to get the downpipe connected.

car manufactures dont really have the catalytic converters in an area where they bolt in... that would make them to easy to unbolt and take off

And I get that. But the headers should be advertised as such and not advertised as a bolt in no modification required item. Having to do the modification is not the issue, it is the fact that they are lieing.
