4" turboback?

[spooledu1st]

If you look at the pic you can see that the turbo inlet is facing the front of the car. The reason for this setup is to fit a huge turbo thus the half radiator. And that turbo has a very large exhaust housing/wheel that is why 4" exhaust. Why would you want to reduce it? 4" exhaust probably is not needed but then again would you want to reduce it!

Jesus Christ, Shep only runs a 3.5 in.

Shep may only run 3.5 but I'm going to run 4in. the Extreme car has like 4 or 5in. out the front bumper so what justifies. Like I said before, it cant be any different than running a 3in. open DP other than the fumes and sound go out the back. I cleaned my G-pa's big garage so I have a place to start laying it out and measuring clearances. Ill keep you guys posted on it.

The green Talon belongs to a friend of a friend here in town. I think he is a member here..

Umm.. The rad is definitely not a factory sidemount, the turbo is a Garrett GT42. And that's about all I know.

Shep used to run a 3.5in exhaust. I believe he has something much bigger now and it exits out the side. Most people knew his exhaust was a restriction last year. Hell, ANY exhaust is a restriction on a turbo vehicle.

I bought my Aem EMS from Horsepower Freaks, the price was pretty fair, Import Evolution has the lowest price I have found but I know nothing about them so thats why I bought from Horsepower Freaks. I would get the ems before the turbo, it'll give you a chance to learn how to use it. Here's some pics of a 4" on a 2g.

Sorry if I duplicate someone, I didn't read the entire thread. But the short-and-sweet of it is:

Yes, cooling the exhaust DOES make a difference. This is why header wrap helps. By insulating a header and keeping the exhaust gases hot, they move easier and with more velocity. If you run a 4" exhaust without the power to utilize it efficiently, the exhaust gases will cool off dramatically and efficiency will be lost.

It may not seem like a big deal, and the exhaust gases are moving at an extremely high rate, but just remember the header wrap example. It makes a difference in the nano-seconds the exhaust spends in the header, and it also makes a difference in the seconds the exhaust spends in the rest of the exhaust.

Exhaust gases slow down as they cool. As your entire exhaust slows down throughout the 4" portion of your exhaust system, the higher-speed exhaust exiting the engine will also slow down.

Local guy is running a 4" pipe on his Talon. If he is at the shop the next time I'm there, I'll grab some decent pictures.

The whole front end structure is missing, or nearly missing. Maybe the bumper is in there somewhere.
Hope that isn't a daily driver. If he rear ends someone, bye bye everything.
