Default Bullet Cat for emissions help!?!?

To pass emissions with the new MO laws I have to put cats on and one shop is allowing me to put a single cat where the Y-pipe merges and I will pass. I bought this cat.... (i'm putting 3 bolt flanges so I can put in a straight pipe once I pass and take the cat out)

http://store.summitracing.com/partde...0&autoview=sku

and the guy welding it on said I need a bullet cat because the one I have is too fat and will touch the driveshaft. I thought this was a pretty slim cat though and I need help finding one that is slimmer to make this work. LET Me know if you guys know of anything... thanks!!

Don't put 3 bolt flanges. Use a V band clamps. Its more expensive but it will be LEAK free and its easier to take it off or put it back on.

That is not a BULLET CAT BTW. AND..a shop is "ALLOWING" you..??????? Check put MAGNAFLOWS site, and you will find small, slim cats...much smaller than those ones.

Most shops wont touch anything that wouldnt pass emission unless its a part failure. I asked for cutouts before my cats and they told me i needed to leave.

Bullet cats work fine and should free up some HP too!! I've had bassani and magnaflow on other cars and they worked great. Car got a little deeper and louder too
