Title: Exhaust manifold
Post by: Hockley on August 7, 2013, 20:43
I've been searching around but can't seem to find any suppliers for branded manifolds. Having come from owning German cars previously there doesn't seem to be much available, unless of course I have completely over looked them.

Can any of you recommend a decent retailer and advise what manifolds you have gone for. Will I notice any difference in sound? Not really looking to make the car louder although a few pops on the over run are always nice :p

Thanks

I assume you are asking about exhaust manifolds rather that intake manifolds.

Your choices are very limited:
1) TRD "Header".  Way over-priced, and difficult to obtain.
2) Cheap eBay "header".  Rubbish copy of the TRD.  Spotty quality, Ill-fitting, short-lived.
3) PPE Header.  High quality racing header.  Expensive & problematic to make work correctly.
4) ZeroExhaust Header.  Expensive.  Excellent workmanship.  Direct no-problems bolt-on replacement.

In truth, no bolt-on manifold is going to yield large gains all by itself.
You can remove the pre-cats from the standard manifold and do as well.
Gutting the standard manifold is almost free, and the result is rugged.
