Does the DNP manifold fit with the stock turbo? I saw two on their website, one for the T3/T4 and another that looked the same, both the same price also. I was just wondering which one fits to the stock turbo.

In a normally aspirated car, differences in otherwise 'equal length' of even 1/4" can compromise the design. I do not feel this is nearly as critical in a turbo application.
Bolesn is correct in that the collector design is absolutely important - but again, more so in a normally aspirated application.
The ideal tubular manifold for a turbo car is one that employs equal length runners with the least amount of bends and of the same cross sectional area as the exhaust port opening, made of appropriate material and of a gauge heavy enough to retain ample heat.
Since it is almost impossible to satisfy the optimum design for all of these criteria in a street vehicle, every product offered will always represent some degree of compromise.

On Turbotrix's site for thier Turbo Kit it is a DNP Manifold however on Shearer's site they say Turbotrix is a reseller... Why is that?? I am getting ready to dump around 5 grand of parts in my car but am stuck on the turbo. Ill post a new thread with all that but maybe someone knows why Turbotrix's pics have the DNP manifold?

We were using dnp for our kit, but we had to modift the sh$t out of it to get it to work. Shearer manifolds are a bit more money, but we dont have to custom fab anything. His are a "true " equal length and are built to last. All the tubing is .110 and the flange is super thick. I've seen alot of other people with 1g style looking manfolds where you can practicly see through the collector.. The website hasnt been updated that is all .

Our equal length manifold has a much better collector design as well. There are so many different factors you must consider when designing the best manifold. Our manifolds have proven to be bullet proof and work really well.

Care to post pictures of your collector? I'd like to see some evidence for such a stellar claim.
I'm not picking a fight here, I just believe in having a properly educated and informed customer. Misinforming people and telling fallacies about a product to get another unit out the door is not good practice in my opinion.
