i think the current piping on my car is 2.5 or 2.75 right now, i havent been able to jack the car up or crawl under and measure...

The current muffler i have on there right now is some ebay brand.

A close friend of mine gave me his RSR exmag exhaust, (the oval shaped one).

Would i be ok to use that muffler?

Overal my question is

Would my car have performance problems if i used 2.75 piping with a 2.5 muffler , or 3' piping with a 2.5 muffler?

i'm worried about backpressure..

to save on money and increase flow would it be better to go 3' to the rsr?

thanks


boosting 7psi, dont know if that will help..

i posted it in the fi section

no one helped..

 

 

A bigger will always be better for a turbo exhaust. The X" to 2.5" muffler won't be a big deal, and the slight increase from 2.75" to 3" won't be very noticable. Maybe to the ricedyno (assdyno) it will be, depends on the user.

The biggest thing to look at is the muffler - a straight-through muffler at 2" will be less restrictive than a 3" baffled/chambered muffler.

 

thank you

any more input would be great
