If the centre muffler for example flows @ 540 is there any benefit in getting a cat that flows @ 750? Whats the flow rate of twin 2 1/2 inch pipes or 1 X 3" for that matter, anyone know? [right][post="343382"]<{POST_SNAPBACK}>[/post][/right][/quote] I think this was tested by some one and from the top of my head the system flows 540 from the CAT back, the factory CAT flowed 300, so if you can get a CAT that out flows the rest of the system then it will no longer be the bottle neck. I think 2x2.25 flow more then a single 3ich, but if you have a 3inch xforce i think anyone of these cats is much better then the xforce. Link to comment Share on other sites More sharing options...

As an experiment I replaced the xforce cat with a straight through 3" pipe and the difference was considerable showing up how restrictive the cat was. For the record though, even with the dodgy cat the 3" xforce system flowed better than the stocky providing better throttle / midrange response.

F6 RAPID Formerly Turbo6 Donating Members 2,332 Member For: 22y 2m 21d Location: North Brisbane Posted 02/02/06 02:54 AM Share Posted 02/02/06 02:54 AM I have a 4 inch SMB dump with 4 inch Metallic substrate cat (gutted) that mates back up to the standard exhaust just prior to the diff. With the 5 inch cat (or even the SMB 4 inch one for that matter), it is the standard exhaust now providing the restriction. I am going to this 5 inch cat and a single 4 inch system straight through with one rear muffler. Should make an interesting sound! If you're doing a group buy with the 5 inch cat, I am IN !!!

[right][post="343469"]<{POST_SNAPBACK}>[/post][/right][/quote] Yeah, but he replied back saying he can do it for 8 and no mention of the price, I will wait to we have 8 people then push for the final price reduction as it $2000 or nothing for them.
