That's a big negative there. :/

They are 2.5 inch. I confirmed that today. Sorry for the delay on answering that question for those who asked.

Oh, thats disappointing to hear. Its still a great price though!

kennejp · 10-26-2010, 12:04 AM

I dont know why people are still doubting these. Lots of people have shown and said they fit fine. I forgot who but someone even took pictures of them when they took them off 6 months later after being in hott and really cold temps outside and they looked great! People are posting without knowing of the proven success. Like many have said its a metal pipe lol

mycoupe · 10-26-2010, 12:11 AM

I'll put up pics once I install mine and tell you guys how easy or hard it was to fit them. It might be a bit though, I have a gnarly schedule with work and school.

wtfmateim65 · 10-26-2010, 02:45 AM

Any near Orange County down to help with install/garage? I dont have a garage or many tools here in Irvine....or can anyone recommend an installer that charges $150 or less?

yamaharecker · 10-26-2010, 03:58 AM

Will they have these listed on their website soon?

Well, some have to defend their expensive AR Design purchase

Why? Is three inch going to flow more air? Because it has to taper to 2.5", and unless they have some venturi developed to speed airflow through the taper from the larger 3", won't matter much.

The big thing is that you get the CATs out of the way, they are what is hindering spool up and airflow from the turbine outlet.

Otherwise, 2.5-3" really not much of a difference with the taper.

Now if you have a true 3" all the way back to the exhaust, now we got something.

Unfortunately, this is not true. 3" downpipes are better than 2.5", I don't know why but there are back-to-back dynos proving it:

The benefits from a 2.5" to a 3" are made when you have a full free flow 3" exhaust..... for all of us with the stock exhaust, or even only axle back, I dont think the difference will be that significant....

dbjb · 10-26-2010, 12:13 PM

Will be helping a friend install his probably next week. He ordered them Friday night and got them today. I guess it helps when you live close to Reno.

Anyways, welds look good. Again, not perfect but much better than the last batch.

Thumbs up to Raceland. Cheap price doesn't automatically result in cheap service.

dbjb · 10-26-2010, 12:16 PM

Question...

Couldn't find this answer anywhere.

Is there an O2 fix that doesn't require going into the ECU box? For example, you install the DP and want to take your car to service. You do not want to swap DP's back but also do not want any error codes. What's the fix?

There is a solution: relocate your secondary O2 sensors after the secondary catalysts, and plug the remaining holes in the catless downpipes. Someone on this forum did it and it worked fine. This is what I am planning to do.
