Make some affordable ones! Give Gavin some competition. 1000 is way too much. OBX to fix theirs to fit and I would be all over them.

Wish OBX would get their shit together. So cheap and even if the welds are bad you could buy, have a shop fix the welds and still be mad cheap.

Its a shame they are so far off from fitting. How do you make a product that doesn't fit its application? I emailed and asked them and they didn't reply. They are missing out on a big opportunity.

shit... well fck me hrdr... >__< i already paid my $850 for the ceramic red headers... at least they'll look better than wrapped headers.

mapleridge · 12-30-2011, 03:48 AM

Do you have a shot of the finished product without the wrap?

fdriller9 · 12-30-2011, 08:24 AM

You need to get your car on a dyno son !!

I've been contemplating deleting the headers and going back to my oem muffler. With a res delete.

I want to keep the secondaries in because I need to pass visual inspection.

My factory headers are quite different. Without the cats they would be even better.

Does anybody know these sims? Do they work?
