Exhaust question.. (involving stock turbo hookup and dimensions)

Hey guys. I am taking the next step and I want to put a full 3" exhaust on. I am wondering -as I still have the stock t25 (just running at 15lbs) if I would need an adapter -- probably one that could be removed in the future when its time for a bigger turbo? Also, would headers to the turbo be necessary or are the stock ones pretty good in terms of power?

I see little sense in having this exhaust "undersized" at any point as well, as time goes on the mods will slowly come on.

The good news is that the t25 and td04 both use the same size 3 bolt flange.

Stock headers are good enough for plenty of power (400)

Awesome, I will leave the headers alone. Though I may take a stab at wrapping them in ceramic to cool down the engine bay a bit. Seeing how they have been recently pulled with all new bolts I am hoping they will come off okay.

I'm assuming turbos can take the little bit of extra heat flowing through if I'm upgrading the DP.

Is keeping the resonator with these cars important at all? I've noticed on 5 cyl volvos (which sound a lot different in the first place) will sound a lot more throaty. But on some of the 4cyl it can make it more raspy.

I have a set of ceramic coated ng900 headers here that I'd sell for less than the cost of having them coated in the first place (no more ng or 9-3s here). But I really don't think they are needed... I'd save the effort fr other stuff...


If you delete the center muffler but leave the rear you will be happy around town but it can get a bit droney on highway cruises.

Once removed the rear muffler but left everything else along on a 900SE, sounded really nice and was not too loud at all... fwiw.

Edit: and I second the motion of the manifold not being worth the effort.

Sweet thanks guys. Nick, I'll let you know if I want the headers, I'm not sure what I'm going to be doing as I basically did something to my rear pads today when I did some hard braking.

This very dumb lady cut me off WHILE I was getting off the exit (she made a last minute decision to get off right in front of me) and I had to slam on the brakes. While doing so (from 70mph or so) the brake pedal stuck to the floor... Long story short the kick panel got stuck holding the brake down and my right rear pad sounds like dragging a stick though sand when I'm on the brakes now.

I was thinking I should step up the brakes with all the tools I tend to carry for plumbing. Now I have an excuse to spend a little more dough... lol Time to thread search.
