getting confused now...


Recommended Posts

can someone explain to me the difference/similarity between the following:

 

Decats

Precats

Downpipes

Wastegate pipes

Inconel Manifolds

 

reason being is that i want aftermarket turbo elbows (divorced ones that keep the exhaust gases spinning) but when i look on ebay US these elbows seem to come with the straight decat pipes. i already have PHNW decat pipes (that replace the cat pipes that go onto the exhaust middle section and back boxes). just want to make sure i know what im talking about.

pre cats/downpipes are pretty much the same thing ie what fits before the cat

 

inconel manifold are just a type of material which the manifold is made of

 

wastegate pipes are not relevent in your case unless you get a turbo kit with external wastegates :)

Depending on your car year you may need to have your decats modified to fit correctly. Thats why they usally come as a set :)

i got a set from 2fast2cool for 130 quid

 

comes with all bolts, gaskets, divorced down pipes and decats for 130 quid

 

get them and sell your phnw ones so it wont cost you that much overall

 

The ebay 2fast2cool ones are stainless and very well made. Not the best stainless metal as they were slightly magnetic, but still worth the money imo

ok thanks guys. ive just spoken to Mickey and he's explained that aftermarket elbows are a slightly different shape and so won't fit onto stock decat/cat pipes. my PHNW ones are designed to fit the standard turbo elbows, so it looks like i'll have to do exactly what Ed says, buy the kit, and flog the old ones. :)
