why would anyone spend that kind of money on anything that has been proven not to give large or much of any gains!
Maybe you should ask yourself that question.
:
Even if it just gave an ever so slight improvement, it'd be worth it when paired with highly modded heads, a wild cam, and a straight-through exhaust with mandrel bent pipe all the way back.
I think every application is different paired to what your working on. Ive used pacesetter on the two other cars, i didnt have problems but for the one on the Geo, only problem there is they didnt come with a seal so i bought a cheap seal from Napa, i ended up buying some expensive out the ass exhaust silicone gasket maker to do the seal. so im hoping on faith that the PS headers will be good on this to, now while it might not give me gain at all it might be for looks... but its more then that, its the small things to... im hoping unwrapped PS headers will be fine on mine seeing how the motor has 215k miles on it.
the high flow cat convt, well if i dont want to go universal or junkyard i havta get the magnaflow high flow direct fit.
from my experience with mufflers, personal experience no data to prove, Flowmaster is still better for an everyday car while Magnalow is good for something that is very well supped up
The main reason not to run wrapped headers, especially mild steel ones (vs. stainless) is that they will rust apart under the wrap, and literally rot. This isn't a point of debate, it's a fact. High performance cars wrap them for the insulative effect, which is worth it for them, as a new pair of headers every so often is nothing when you're looking to squeeze power out of something.
The universal 3-way high flow is probably best in terms of budget, but the $200 magnaflow is almost a bolt-in, though it looks like they don't come with the hanger attached (or at least not welded on, some versions show an optional clamp-on hanger).
Flowmaster does "better" on regular cars since the mufflers flow less but people overdo it with the pipe size. Since people put a 3" exhaust on a car that just needs 2", the restrictive Flows bottleneck it to make the exhaust velocity closer to that of a 2" system, so sometimes it DOES work better. But in a backwards way.
I'd say Dynomax, Magnaflow, Borla, etc are all way better choices. But for those who like the Flowmaster sound, to each their own. Just get a larger size muffler than you think you need if you must have Flows.
As for the headers, the smaller primaries and the crush bends on some of these makes me wonder if the flow is any better, (or actually even worse) than the stock manifolds? They're 3-into-1 tubes, but they are pretty big openings.
I think Xeek should test out the motor when it's all done with manifolds, the JBAs, and the Pacesetter so we can finally know what flows the most.
