Finally took some pictures and video from my 4" cutout installation
the only problem i have and try to solve is the cel comes on after

Where did you purchase those and what did they cost you? Any difference in power with cutouts?

 

i got them from dmh
http://www.dmhperformance.com/
i m not sure about the power but the sound is loud like racing
and i found out your tuner can fix the CEL
good luck
if you ever do it be sure you take off the exhaust of the car its much easier

 

Are these direct bolt-ons?

 

Well you have to cut the exhaust and weld the cutouts
search DMH cutouts in the forum and is a diy for it
any questions i will be happy to help

 

Hi,

Just noticed you are from Boston and I would love to hear this in person. Buzztt is also from MA.

 

Very cool! I was thinking of doing this a few years ago.

How long have you had them on? I have heard that the valves have been known to sieze up because of high heat on turbo'd cars. Another thing to think about is the hot exhaust gasses working their way up into the engine bay at speed. I have heard of guys melting their wiring harness with wastegate dump tubes off the headers.

 

the turbos sounds awesome with those things

 

Are these units causing what appears to be a hugh amount of rust under the car?

 

What an amazing piece of engineering. Excellent upgrade.

 

right now i have the car on the lift in my house,working on turbo upgrades couple weeks i be done,i hope give me a buzz!

 

i have them few months and dont use them all the time
i dont hink the gasses going up to the bay specially when the car moves
so far so good ,no problem
it cost me about $600

 

yes the turbos sound really good

 

yes i think is excelent upgrade specially with cost of about $600
and if you welded yourself will be $300 something

 

I would imagine it would be a good bit louder outside the car with it down on the ground vs on the lift. The noise will bounce from the pavement! The valves can and do occasionally seize up but I'd hope that the companies making them have improved them over the years. Even if they do seize I wouldn't think it would be impossible to free them again. I cannot see wiring or anything else being in danger unless the exhaust gas were directed towards those areas, pointed down like these I see no issues. Sounds good and having the ability to sound stock with no drone has got to be VERY nice too! Can you simply crack them or is this a binary on off installation? I've seen them setup to be boost sensitive and other things as well, not sure how much sense it makes to get too crazy...
