I Have A 3inch Catback What Would Be The Best Downpipe Outt That I Can Boltt Up To It ??

And Would It Take Out The Deepness Of My Exhaust???

 

probably should go with the rest of hahn exhaust products

 

i have the DC sport exaust,a nd i went with the CA 2.5 inch dp with a high flow cat, and it made my exaust much much much louder, i like it alot.. but it deffinatly changed the tone and the loudness of the exaust
