I'm still exploring my angst on some "light" upgrades; plenum porting, headers and a great tune. I do value the opinions of those what are actual users.
My question today is on headers. What is REALLY the difference between some of the major manufactures? There is a pretty good size pricing differential between SW and OBX and other, although all users swear by them. My priorities are: 1) fit and installation ease; must fit to factory pipes as I'm keeping mufflers to reduce drone. 2) overall quality of constructon 3) performance gaines. yep, it would be nice to feel a pop 4) sound, tone as I'd like a bit more sounds but drone is a no-no I'm a pretty sane driver, no race tracks but any freeway on-ramp is my own personal 1/4 mile. "flow at all costs" is not a thing as a couple of HP difference is not going to cause me to sweat. What is the BEST value? Thanks!

I went with OBX.....I too was going to keep my stock mufflers but went with the entire system...
I like the OBX and you can't beat the price.......A couple of HP here and there on a set of headers in my opinion are not a deal breaker....Double the price for a different system was.... Sent from my LG-TP260 using ZR-1 Net Registry mobile app |

I used the OBX headers and Maximiser cat back. (same as obx) The headers fit with out any modification. The cat back I had to extend the pass side after the fake cat with a maybe 5" piece. I also welded it all as I "massaged" it to fit properly. Sounds great, No drone.

Bill, I know you replaced your resonator with the Mangaflow resonator. Are you planning on keeping the stock exhaust pipes as well as the mufflers?

OBX from front to back.
The OBX headers did not clear the steering shaft and needed to be modified. I notice the OBX SS exhaust is showing rusty spots. Can't beat the price. |

I had an opportunity to display OBX headers to SW set. They were identical except for OBX collector being about 8-10" forward (shorter runners) to compensate for fake bullet cats. As for the OBX cat back vs. Corsa, dimensionally identical (may be even possible to mix and match components from one to the other) but internals of resonators and internals of mufflers were different - OBX being traditional perforated pipe with housing filled with sound insulation vs. OBX with helm-Holtz chambers. Again, no complaints over OBX. As for the steering column clearance we hear periodically, I think this is due to steering coupler location variance on steering intermediate shaft depending on the year. My 94 coupler is almost right up against the steering box and had no issue clearing the header. Earlier year cars seem to have coupler close to the middle of the intermediate shaft.

Yun, my steering column rubbed against the header, and ceramic coated, it's very abrasive to the touch.

No, if I could find a true dual, with the stock tips, lower back pressure and no drone.... I'm in!
