Celica Forums General Discussion Exterior Turbo Exhaust

I have the Tanabe Exhaust, can you run this with a t3\t4 turbo or do you need somthing different

What does a turbo have to do with an exhaust?

yep...nothing...
your exhaust will be fine.

actually the turbo affect the exhaust a lot, if the tubing past the turbo is too small, you will not get full boost of the turbo, and it would cause the turbo to be too hot fron the backpressure of the heated exhaust

yea that's why you don't use stock...
the turbo is spooled up from the exhaust isn't it?
doesn't it use the extra whatever or something?

Yeah, with turbo's you're suppose to have 3 inch piping, not 2.5, which is what most people have on non-turbo cars.

yes, but think of it like this, would the fluid from a bottle come out faster if you cut the neck off, or if you just took the cap off

When you have a turbo, you no longer need backpresure (or very litte). So when you have a turbo, the most open free flowing exhaust is the best. (Hence the 2.5"->3" post)

I once ran my old car (w/ a T3) with no exhaust (downpipe thats it) and it flew, I later threw on a pipe with a muffler and it didnt hit quite as hard.

I would think that if you are going T3/T4 I would highly consider doing a custom exhaust.

But then again I dont have air care here

as long as the diameter of the exhaust exiting the turbo is maintained through the entire exhaust, then you will have a good system for a turbo

thats why i was asking about the tanabe exhaust, i am installing it in about 3 weeks and want to get everything ready so i dont have to be without my car forever

turbos needs 3 inch piping
