Hi all, Solid fabrications in the UK make a big bore manifold with a 3" collector. Has anyone run similar and is there a large benefit over the oem manifold (sorry header for the guys over the pond)?

Im running the HKS 75mm single and would get a matching 3" decat to complete the system.

Thanks for the info in adavnce

If i were sc'ed id def be interested in this. 3" straight pipe and exhaust showed improvements even on an na setup over 2.5". Plus, i prefer the deep tone of a 3" over anything smaller on our cars.

Thanks for your response. Do you know if there are any other manifolds with a 3" collector?

I've been advised by my tuner that I may actually loose midrange with a manifold like this, and that if I want to keep or improve Miranda I should go for something like the Toda

I have a modified version of this manifold.

I removed the 3" collector and change it to fit 63mm. Made more power like this.

Exhuast is a 63mm, 60mm then twin 50mm dual

You modified the Solid Fabs Manifold? Ive deced to go with the tuners advice and ordered what hes advised. Hope to see the results in a couple of weeks when the cars remapped.

Thanks for everyone's help

Yes that's correct.

What has he advised and who is mapping the car?

TDI North are mapping the car, They advised that at my power level i'm actually likely to loose a lot of mid range power but increase at top end going to a big bore manifold. I would actually prefer the mid range so this put me off. TDI also said they have had seen good results from the Tegiwa manifold which i believe is a TODA copy and couldn't fault the quality so I've gone with that. Hopefully ill have the car back by next weekend so i can report on the changes
