Anyone try these one's out? They are about $335 shipped for the long tubes and y pipe collector,

1.875 headers, 2.5'' collectors

I think with bumping them up to 3'' at the y to the cat back would be sufficient?

Any one buy these and see how they fit?

I just ordered the same thing, albeit a different seller. They all come from China anyways... Vowed I was done with China stuff this time around, but with college costs, I couldn't justify dropping 1300 on headers. Waiting to see how these will fit with 4wd.

 

Back to the hump on the driver's side head. I have them on my Z71... They're like a 200 page thread on them around here somewhere.

 

I know what the ad says, but those are not 1 7/8" primaries. You'll need to read that thread dmelvin mentioned, and be ready to deal with the hump vs plug wire issue.

 

It's like they take one step forward and 2 steps back.
1 7/8 " primaries and 2.5 collectors(doh!) and the hump is back (double Doh!)

 

Yeah fully expecting them to be 1 3/4...

 

Why not get a set of callies or tsp's for about the same price? Or am I missing something here?
