What kind of exhaust set-ups are you TC/SC'd people running? Is it a good idea to buy the cattman mid-pipe and eliminate the cat for a test-pipe?

 

it seems as though the general rule of thumb for boosted maximas is 3 inch exhaust. i definitely wouldn't go smaller myself and bigger might start getting hard to stuff under the car and may not be needed.

 

cattman 2.5 with random tech cat...

 

3inch yeilds most WHP/WTQ

 

Are the Cattman headers for 01's 2.5in? Also, who sells 3 inch b-pipes?

 

yeah headers are 2.5 in.... warpspeed has a 3 inch b pipe. Bear in mind they use these pos clamps with a bunch of precut bends that you kinda put together and clamp together.

 

hmm I have the WS y pipe, 2.5 exhaust from the catback. (stock cat) Anyone know the size of the ypipe? I got it about a year ago from a GB.
Ill be turboing soon... Ima have to live with 2.5 for a while

 

So the warpspeed is not good or are the clamps just a pain in the ***? Also, what diameter is a stillen exhaust?

 

I am running a 3" downpipe right off the turbo, to that I am going to connect a 2.5" catback, and going to have a 3" electronic cutout between the downpipe and catback so that when I need that extra 30hp I can have it, but so that when I don't need it I can have a car that is pretty quiet and retains sleeper status.

 

which cutout??

There is a local sc'd IS owner who did that and his leaked. He had to use some hi temp liquid gasket to get it to be 99% sealed

 

how is that with noise?

 

JAY25s was was about equal to the sound of mine with Greddy SP, maybe a little louder but not much

 

Do all cuttouts have this problem or was it this particular car? Just curious because i am going to buy a boost actuated one from ATP

 

what's Jay running? 1 resonator and 1 muffler?

 

Mine is loud and crappy sounding under normal driving..


go WOT and it's great.

But I have no resonators and a fart can muffler

 

yeah waking up the neighborhood in the middle of the night w/ the exhaust can't be good.

 

When I was down there over the summer he had the Warpspeed 3 inch set up with a straight pipe for the cat....if you search he has posted pics and specs of his exhaust set up in this forum several months ago

 

THis one

And from what I have read on the mustang forums, the best sealing cutout is the manual type that have nuts holding it in place.. just easy access

 

All electronic cutouts seem to have that problem from the research I have done. Just some RTV red sealant to remedy it. I don't want to have to get out of the car to open it.
