Aftermarket Exhausts

Hi Chooka, Yes, the system does come with the Cat.

Jordak, all I know about the cats is that they are Hi flow metalic substraight, one a 3" the other a 3.5". I do not have specs on flow rates etc.

Thanks, XR6ISM

It is and you will get a power increase also. When these systems were tested on my car by Bestmufflers (who then send them on to Xforce to start production of the kits), my car gained 14rwkw when standard with the 3" system. The only draw back is that this system will not run more then 270rwkw.

The 3.5" system has no problems with holding 300+ rwkw.

I know of a car with the 3inch xforce system and its running 290rwkw..

I guess it depends on who's dyno and how it was tuned.

With the 3" test system on Spiro's dyno the car made 270rwkw before Spiro said I need a bigger exhaust system. At this stage Chris (from Best mufflers) made up the 3.5" system which when put on the dyno jumped straight to 290. With some extra tuning we left it on 303rwkw.

it was tuned by spiro on his dyno

I picked up a 7 month old APS exhaust for $1000, flows 70% better than the standard xr6t stock exhaust.

This is interesting, cause Spiro managed 270 from mine before I needed the system changed.

Good to know that its capable of more, thanks for that info mate.

the 3" xforce with cat replacement has seen 400rwkw and better everyday driveability

the 3.5 when available with the twin dump and metal cat not the current normal cat made to look like a metal cat will be awsome!!!!

DW.....even though Xforce may make the split pipe used in my car, we have scrapped the split pipe for the 4" pipe that's currently on the car.

Spiro has confirmed it has had a positive effect on the car when it was last tuned and there was a power gain.
