just like the title says. I have a 3 inch vibrant exhaust with a whisper resonator. it actually is very quiet. Nothings wrong, been on the car around 7xxx miles now, no dings or anything. Im looking for a 2.5 inch exhaust in good shape. magnaflow etc.

 

So I guess no GMPP sport trade? (2.25")

 

you should trade! yielded 12whp gain on a ss/sc dyno proven!

 

i have a magnaflow 2.5 but i have a question would a 3 in help me at all lol... almost stock besides exhaust and K&N. just wanting to figure out if my car is going to drop on its face and have no back pressure.

 

just a 3" catback wont make a difference. if you have a stock manifold and /or downpipe. an all 3" exhaust from header back would lose some power though...

 

^ i dunno about lose overall. youll prob lose some down low to gain it up top. I had as intake and my full vibrant exhaust (header back) in the summer with no other mods and i pulled really well up top. a lot better than stock. I did all the mods in the same day though so i went from stock to full exhaust and intake. and yes, i only want a 2.5 inch exhaust. gmpp is too small for my 2.6 pulley haha i think so at least. please correct me if im wrong

 

you could stand to gain from a 3" set up. you are probably moving enough air with that 2.6" pulley. however someone on a stockish set up is not moving enough air to make any gains with a 3" exhaust. He would have to rev it way past the useable rpm range before he saw any benefit

 

whatever lol i want a 2.5 inch exhaust. lets trade!
btw: thanks for the info

 

pm'd

 

TTT come on guyssss

 

very good deal.. bump it up for you buddy( 2 bad it would kill me on power lol( no back pressure) or i would trade you for my magnaflow.

 

i have a magnaflow that was on the car for 10k
pm me and we can talk

 

if you want to deal with shipping, i have a meagan i'd be willing to get rid of

 

ive also got a megan and i could drive to you if you wanted.
