i have ppe and no complaints and excellent customer service. i know of two people with sikky that the passenger side o2 bung was welded in a terrible spot. the o2 sensor ,once installed, actually hit the frame of the car. luckily for one of my friends...another o2 bung was welded ,from a previous owner, on to correct this but another guy just had this happen. now the sikky headers have to come off and have an o2 bung welded in a better spot.

taking mine back to the shop next week for inspection due to this exact issue. we are going to see where exactly the contact point is and if we can't fix it sikky will be getting a call for sure. fyi, i have had these on the car for about 2 1/2 weeks now and noise is getting worse under load around 2.5-3k rpm's.

So you got them installed! Next time you go drag racing, let me know. I put the stock battery back on and the stock wheels so it's not longer ultralight. I'd like to do a PPE vs. Sikky comparison. We can keep things as equal as possible. The only difference is the rotors, headers, and coilovers and I weigh a little less so I'll keep the spare and jack in to make up for that difference.

Ah gotcha. Just hope a 12.0 but a 11.99 would be fantastic!

Wow, I think it seems that PPE is the way to go, considering it's only around $50 difference in pricing. Who wants to tweak and adjust a bunch of little half-*** issues that shouldn't exist with the Sikky's in the first place? Great thread!

Um, this thread is 3 years old bro. Comparing old products. Sikky, for sure, has a new model out. PPE now has Equal Length headers as well.
The new Sikky headers are MUCH improved and make slightly more power and install easier than PPEs (supposedly....I can't verify that as I've personally never installed either header).
But apparently you did a search and found this thread.....do some more searching and find more up to date/current header threads!
