Biguns Posted March 9, 2011 Share Posted March 9, 2011 I bought a couple of exhausts for my supra of the forum but i have no idea which one would give me better performance on an N/A the first one i have just fitted is a stillway and it sounds great but has a cat and extra box on it The other one is on the left below has a second decat pipe and no boxes, will this be better performance on an N/A No idea what make it is Thx i just dont wanna be a tit going backwards and forwards to the garage.

Nic Posted March 9, 2011 Share Posted March 9, 2011 Is the Stillway titanium? I'd fit the Stillway as it should be the quieter of the two. The difference between them will be negligible, there'll only be a few hp between the two at the most, go with whichever you prefer the sound of.

keron Posted March 9, 2011 Share Posted March 9, 2011 The still way will be quieter, bit you may lose performance due to the bore size on it...it looks like a 4''? The one i just sold you is a 2.5" iirc so would suit the na better. All to do with back pressure etc... Link to comment Share on other sites More sharing options...
