WHich is the largest exhaust available for the single turbo TN kit? I want a 3 inch single or dual cannister but it must fit the TN kit. Which should I choose?

 

The Topspeed pro-1 is probably the most free flowing system for the turbonetics kit. This system virtually has no back pressure. The single exits like the JIC, Apex'i are a great choice too. Btw, these sytems will be quite loud even with the turbo.

 

Aps has a 2.5 that should be good..........

other wise for a ST i would just go with a Single exhaust like the JIC

 

Your more than likely going to overboost. Wait for the TN fix they are making before going with a new exhaust like the Topspeed Pro-1. Any cat back exhaust will work as long as it is not a true dual. I'd also have to say for pure performance the Topspeed Pro-1 for dual cans, or any 3" single will be good. Some like the single can look. I can't stand it so I went double. The single can leaves a hole in the bumper cover on the passengers side.

Big bonus... the Topspeed Pro-1 on e-bay is $479.

sorry to highjack his thread but what is the loudest single exhaust nowadays?

What about the Invidia SS Full catback? Has anyone heard of any issues (good or bad) with this exhaust and the TN kit?

 

So an Injen dual exhaust will cause an overboost?

 

I have a Full Ti 80mm, slightly larger than 3" which is 76mm, and it has No resonators and with the TN kit it is still LOUD AS F*CK. I love how it sounds though, I like having a good sounding loud car, nothing like letting people hear you shifting going down the track...IMO there isnt a lighter(9.8lbs), louder, larger, straighter exhaust system, if there is I havent seen it.

BTW-Jet has experienced overboost problems like a few TN owners, but with the JIC mentioned above, I boost to 9psi, no spikes. SOme cars exhibit overboost, others dont, its up to you if you wanna take the chance with your kit before TN comes out with a fix.

 

Well I will have the car tuned later for 9 psi. anyway, thanks for everything

 

It doesn't matter if you have the car tuned for 9PSI if you have uncontroleld steady boost @ 13psi.

That's true, can a boost gauge be used to lower the boost and hold the boost or does one need to upgrade the wastegate?

 

You will need to fabricate a new wg mounting location for more effiecient flow to the wg. I used a larger wg as well. It solved the problem. For your reading see below. Boost guage ??? I think you mean boost controller. The answer is no it won't help.
