alright I have a 97 prelude with a drag gen. 3 kit, precision 550's, p72 with hondata s300 @ 8lbs of boost. the car was dynoed with a three in open down pipe about a week ago. Today I just finished a custom mandrel bent 3'' straight through exhaust with no restrictions and a magnaflow 3'' in/out muffler, the car runs great and couldnt sound better.(hope this is enough info.) now my question is how well is it off after I did the full exhaust today? because it was tuned on open downpipe is it going to effect anything? thankyou

 

I don't think it would change anything.

 

alright cool, I prolly wont need another tune or anything right?

 

it might run alil rich...
