4in exhaust

[shadyford]

I'm thinking I want a cat back 4in system with no muffler, I have to at least leave the cat shell on for emissions , I've looked at a few web sites and only see turbo back w/o muffler. Where should I be looking? Thanks.

Call then and tell them exactly what you need... im sure they can set you up with the right kit

And BTW... I would suggest a 4" turbo back with cat without muffler!

Get a couple of 4" to 3.5" reducers, cut down the pipes on the cat and weld the reducers on. Cut a piece out of your 4" exhaust the exact length of the new cat setup. Now use 4" band clamps to hold in either the pipe section you cut out (cat delete pipe) or the modded cat. Takes 15 minutes to swap out at the track etc. or leave the cat off till you need to get it inspected.

Ok so I will go with turbo back no muffler and mod my cat to fit, it will be hollow but look the part. Thanks.
