How much Hp will I lose if I remove my 3" exhaust?

[zigger]

Hey guys.. so I honestly can't take the noise anymore of my 3" custome exhaust along with my 3" cpe downpipe. So I'm thinking of just putting the stock exhaust back on and leaving my dopwnpipe , intake , bov and tune as is.
My question is how much Hp will I lose?I dynod 300 awhp and 330 t/q. Also will removing the 3" exhaust affect my tune at all?
Thanks.. I think I may lose 8-10 hp max b y removing the 3" exhaust..but I want to know what u guys think.
Thanks..

are you putting any cats back on?

put the stock pipes back on and get a cutout welded on they are good and cheap compared too catbacks and you can turn them on and off but they are loud..... so then you have the controll of it being off and on

not to purposly change the topic here but did u have any resognators or mufflers and was it really that annoyingly loud? or are u just the type of person that doesnt like loud noise?

Just get a good muffler shop to throw on an exhaust. I got a Magnaflow muffler put on my CPE TBE and it cuts the noise down an awful lot. Still have some tone, but nowhere near the buzz/drone that it was before. Definitely worth the $300 or so. They'll cut off the last few inches of the straight pipe and keep all the mandrel bends, and stick the exhaust on the end. Pretty simple for them to do.
