I notice these kits are reasonably low in price for a 35r kit, how do these perform?

 

Poorly.

Keep shopping.

Best bang for the buck IMO, Buschur's kit's.

If you wanna spend a little more money, check out ETS.

They have a sub forum in the vendor section.

 

i have the 3071r kit and its been great. little low on the #'s but i have finished my set up yet. so its part my fault. fitment is a little tight side.

 

Honestly, if you looking to build a kit for cheap, I would rather try out the T3 manifold and downpipe off of Ebay (full-race look alike). People say it will crack, but for $300 I don't think you can go wrong. Go ahead and flame me =)
