I have been thinking of getting a cooleeze magamouth in the 4" version. I would like to know if anyone else has one. If so, do you like it, does it make a difference etc. ? In theory in my mind it seems like a great product.

Thanks

 

I am thinking about getting the flange later.....It sure looks like it would be helpful to spool up the turbo faster and help egts.

 

You can answer the question yourself. On a stock HX35 the exhaust is pushed through a hole the size of a quarter on to the turbine and exits out the turbine chamber through a hole not quite 2.25" in diameter. Given that information, how much difference in performance do you think the megamouth will make? Think about it.

 

It's a great idea and there's no reason it won't help but to me it's not worth the money.

 

The most benefit will be realized during full boost and open wastegate conditions. So if you are a stocker, and don't run to the wastegate all day, the benefit may not be as great. I am sure if you were running against the gate all day, it would be a nice improvment.
