Okay fellow tuners,

I got a question i have been searching over in hour on this site on muffler piping and have not found the answer to my questions.
I have a magnaflow muffler but i am confused to what piping i want to get for it i was thinking about 2.5 but i read that 2.5 you lose low-mid range torque. Then i thought 2.25 and i read about 2.25 and i found out that 2.25 doesn't really change anything about the performance of the car. So i was wondering what are your thoughts about the piping sizes and also could you plz tell me what piping you have on your car and what it does for your cl.


Thanks your help will be appreciated.

 

2.5 is going to be the best. The power you lose will be gained back when and if you get headers.

 

KC's right. However, with 2.5" piping you're going to gain on the higher power band. I chose 2.5" piping because I'm running nitrous in my car, so I need a less restricted flow.

 

most universal mufflers have a 2.5" inlet so you'll probably have to get 2.5". Make sure you know what size the inlet is on yours.

 

actually, most magnaflows are either 2.25" or 3"....only a few are 2.5
