Damien_BAXR6T Member 31 Member For: 13y 8m 26d Posted 31/03/11 08:41 AM Share Posted 31/03/11 08:41 AM hey guys,some of you know me by now but im fitting out a 02 BA xr6t for when I come off my P's in september.by the time I will be driving the car it will have:InjectorsValve SpringsTuneT56 Short shift (not really needed in the exhaust making process but just to give you all the info)Fuel PumpTurbo oil lineHot Side Piping from RAPIDUB CAI from RAPID (going for the crazy spool and intake sound :D )now my querry is, which exhaust?a mate of mine who works in a exhaust shop says 4" dump, 3 1/2 " cat, and twin mendrel bent 2 1/2" cat back (hurricane system)he says they sound gnarly while having no drone and the sound is just unrealmy mechanic says they use the xforce 3 1/2" system which 4" dump and 4" cathe doesnt say what the sound is like but does note that it is deeper from his POV, no complaints from his customers he has used it on and much easier to make power with.im just wondering if you guys have came across a system which you find to be good for performance while also sounding absolutely insane.most types of systems will suit my performance needs as for the next couple years ill be sitting at 300rwkw or so as my mechanic refuses to go past that on stock bottom end, which I am happy with as I dont want the car to miss a beat. and I trust his opinion as he has been working on them since 02 or so:Ddown the track (3 to 4 years) I will be getting a fg f6 bottom end and plenum + intercooler so I wouldnt mind it if the exhaust im getting will be able to handle the power that that combo will then generatethanks for taking the time to hear me out and cant wait to hear from youcheers, damien Link to comment Share on other sites More sharing options...

spoolxr6 Member 312 Member For: 14y 1m 4d Posted 03/04/11 03:07 AM Share Posted 03/04/11 03:07 AM its actually samller than 2 1/2". I measured both the internals of the xforce muffler and it was around 1 3/4". If you use the XFORCE 3.5" just fit a straight through muffler at the rear and the system will easily support up to 400rkw. It sounds nice and deep without the drone.
