Hi all, does anyone have a set or know anything about the above headers sold by GM Motorsport? Apparently they bolt up to stock cat back and aftermarket systems, no ground clearance issues either. Wondering how they compare to other brands? Thanks.

I have a set of 1 3/4 and 100 CPI cats on my Calais

Equal length primaries, 4-1 design, they flow well, sound great and fit well

No mate, I have a Manta 2.5 inch, but it is the same length as the stock catback.

If your not totally sold on the Ramjets, I have some real good condition HSV R8 SV 340 Tri Y's and factory cats the will bot straight up to your stock catback. Low cost, good gains, sounds nicer that stock and wont need a tune to keep the engine light off.

Even through the 2.25" factory catback, the R8 340 Tri-Y's made a difference on my car, both aurally and performance wise. She felt more willing to rev and not so laboured do so, mated to an OTR, 2.5" 7 Series Xforce and a tune; she gets up and boogies like should've been from factory.
Bear in mind i have an 06 VE SS-V L98(6.0l). But you should notice a good gain in your 6.2l with just the headers and cats.

I have the 2.5 inch HSV mid section on mine as well. Only reason I have the HSV's for sale is I upgraded the headers plus high flow cats, OTR and tune. Made a big difference but obviously cost a lot of coin too. With the HSV tri y's, 2.5 mid section and just the factory tune, it was exactly as you described rucxy. Had a nicer note than stock and felt more alive, especially from around 2k up. Probably picked up around 10kw I'd estimate for bugger all dollars. To be honest and in hindsight, I'd have just stuck with them and just put higher flow cats on and a tune and been nearly 90 % to where I ended up anyway if I could go back an do it again.
