Well, with all the I wanna shoot flames threads I began to wonder. I know mine will. I can tell from all the farts when decelerating.

My question is,
Will Racing Beats main cat replacement pipe be a straight bolt on in my car?

I have whatb seems to be Bonez super flo downpipe and high flo cat.(it may be RB's but doubt it)

It came witht hte car so I don't know.

I then have Corksports single Catback.

It seems like I should be able to just swap it in or will there be a prob on fitting?

Then we have the ports...
Does their S4 N/A one really work or is there not enough back pressure?

Will the removal of the cat increase sound? I assume so.

 

Buuump buuump bump. Sounds of my fifteens hittin in my trunk.

Someones gotta know

 

i believe you need to get rid of your bonez highflow cat, your probably shooting flames with that setup already but with a cat on there it takes it all in, and your not going to see anything unless you run it with no cats.

you can get around the 6 port actuation with the RB streetable header, or you can do what i did if you want TRUE DUALS and get the modified RB Road Race header from mazdatrix with a O2 sensor fitting welded on there for proper 6 port actuation.
