Im looking into getting a mxp exhaust, does anyone have one and did you feel an increase in horsepower? I cant find any dyno charts and I was curious before spending all that money on this exhaust? thanks

 

help plz

 

It wont give you much gains unless you have intakes, a tune, and test pipes or hfcs. You already have the gen 3s so There might be a +5 gain

 

A local member has it and she put down some strong numbers on Cobb's dyno with the MXP and Injen CAI. No before and after though. Just compared to my car (with an Invidia exhaust, K&N's, and a Cobb tune) she put down about 12-15 more HP.

 

What were her numbers?

 

Any more info on this? I have the same set up.

i think average with intake hfc would be between 10-15 hp for most exhausts

 

It's safe to assume that all true dual exhausts will be similar, or enough so that it's not a good idea to choose them based on power alone. More important factors would be appearance and sound...make sure its a system you will be happy with from these aspects.

 

I think she did 282 HP. I think I did right around 270 HP on the same day (I think we may have both been a little lower than this, but it was close). This was Cobb's Mustang dyno that reads lower than a dynojet.

It is Heat, and she is on here. You can probably PM her for details. This was over a year ago, so I am not sure what she can tell you. I just remember she was 12 HP higher than me, and I think I did around 270.... I've dyno'ed on the same dyno 3 times, and did around 260 HP stock, and got up to 270 with the Invidia exhaust and tune (my car was not tuned with the exhaust installed).

 

any more info?
