small exhaust will not make the turbo over boost, if anything it will hurt boost in the upper RPM.

also with a WG dumping it will be loud, i tried mine like that for a right and it sounded like a straight up race car. i ended up routing it back into the exhaust.

 

Thats what i meant.
WG routed into the exhaust causing high boost/boost creep.

I had my STS kit WG dumped and it was highly annoying and stupid loud.

For now im just gonna run my stock 1500 cat back along with the WG routed to the rear with a small muffler or something. quiet and simple.

 

if anything throw a better muffler on it.

 

Thats my other issue.. i want it quiet. thats why i was lookin at stock Dmax stuff.. 3.5" and a quiet muffler.

 

i just put a muffler on my brothers, i forget what it was called but its quiet like stock with a valve inside that opens at 3k rpm supposivly, you can hear it open and it is a straight flow

 

I was looking at stock dmax stuff when I got to looking for exhaust but when a brand new 4" kit was 325 to my door I stopped looking. No cat, no dpf, no hangers to have to cut off and re-weld. It's a big muffler and not restrictive.

Diesel performance systems inc.

Noticed they have a 12% off sale today.

I have about 6' of 4" pipe left over because I bought a crew cab kit.

 

big power can be made with a 3" exhaust pipe, im talking like 750-800rwhp,. much more than 99% of the stock motor boost guys on this board

 

What brand?



I got your PM.. thats tempting, but im still waiting on this stock Dmax exhaust from a guy.


Oh yea i know, thats why im looking for a stock 01-06ish stock exhaust. 3.5" with a big quiet muffler

But for now, im just gonna hook it to my stock catback.

I have another catback with a magnaflow muffler i can try.

 

Did you ever finish this setup?

I ended up dumping my wastegate on my new hot pipes...



Partial throttle in boost it sounds like a harley is driving right beside me
At WOT everything is loud anyway, especially with the cutout

Playing with the boost controller, I can set the gate open pressure, so if I set it for 10psi, the gate stays completely closed then opens suddenly. So unless you are deep into boost it is pretty quiet.

 

yep.. super quiet
