Exhaust and de cat S4

[marv]

hi i am wanting to no what exhaustand de cat pies are best, seen the ones one ebay are they any good

 

[Broken Byzan]

They get a good rating on SRS.

Once i have worn my mild steel swtup out, i might actully buy one of those to make it fit my TQS

i got one , quite good when it was the s4 was working , i ran with rs4 piggies and it was still to quiet for me i was just about to remove the rear box , sounds really nice when thats done

mmm i woz thinking milteck but there mega bucks, what sorta bhp you get

 

[andybnwc]

No idea but its one of the better flowing systems , piggies and twin systems are pretty good , i dont think the milltek will gain much more but the build quality is much better on the milltek.

[andybnwc]

with all cats out and the centre and rear boxes still on it wasnt loud at all just a nice sound.
