3" Turbo Down pipe: New exhaust?

Turbo down pipe is 3" but I dont really think the 3.4L warrants a 3in exhaust. Unless I upgrade the cams, internals and increase RPMs to 6-7k, I dont think its going to do any good. Should I stick with the 2.25 or do a overhaul to 2.5?

Kind of on a budget...

 

stick with 2.25 motor was designed around this size

 

Your gonna run a turbo. You want as little back pressure as possible. Less back pressure means faster spool time for you. You will want 3" pipe.


Or. Get a 3" electronic cutout to be attached right after the down pipe. Then do a 2.25 out with a nice muffler for DDing. Open the cutout for uber loud noises and faster spool for go go go fast situations.


Either. All custom no matter what...


Welcome to turboing

 

That's what I figured but no first gen 3" kits... Ill have to do something custom... I love that electronic cutout idea, but might be too complicated and $$$ for me

Time to call my local fabricators...

 

Cut outs aren't that bad.

Cause really 3" straight pipe would be best for performance. But 3" turbo back and a divorced waste gate will be fucking loud...haha.

Really not hard to incorporate. Just give it to your exhaust guy. Tell him where you want it. Then do some wiring for one switch.

 

That shit will be loud when switched over ... I like it

Wait, scratch that... Its still a 3" pipe... If I can keep the stock and use this to have a secondary 3" short pipe I would be all over it... They dont make a 3" to 2.25" adapter... Ill have to look into this a bit more...

 

yep would be loud a shit. But super bad ass. haha

look up some youtube vids with them. Pretty sweet really. very handy.

Your exhaust guy will have to make an adapter. shouldn't be too hard.

 

I'd just go with full 3" and be done.

 

You say that..till your on the hwy...haha

 

That's when it will sound best. WOT under a load ftmfw.

 

Ideally full 3" turbo back custom exhaust..... If on budget plumb 3" dp to oem exhaust and leave wg open to atmosphere..... this is how mine was setup and made over 420+whp and 500+wtq 16psi but was annoying loud! Will be loud as heck so you may need small muffler on wg pipe. Could also get cutout as mentioned but that loud as well, and could add muffler to this pipe as well. In short budget will be loud and if adding muffler to cutout or wg pipe to quiet down may as well went full 3" for cost you will have in it. Hope this helps.

 

Ahh, reminds me of the old glory days with a 3000GT VR4 that had all those things factory...

 

And burned more oil than Saddam Hussein...
