craggsy 91 Posted December 18, 2009 Report Share Posted December 18, 2009 decat will release a few more ponies, as will the manifold.If you have the money then change the lot, wont ever need doing again if you get a stainless one Link to post Share on other sites

PhilippVR6 0 Posted December 19, 2009 Report Share Posted December 19, 2009 Decat!My previous 2.8 was measured on a rolling road after installing an empty cat. The figures where 188hp and 173 lb ft. with the empty cat. as the only change. Link to post Share on other sites
davee 0 Posted December 23, 2009 Author Report Share Posted December 23, 2009 right got a decat fitted today and a long life exhaust from the decat backhave a small silencer fitted and the back box is fairly small aswellnot to loud but when i let of the power i can hear a small back fire. what causes this also the system was made with 2" pipe is the backfire caused from lack of back pressure Link to post Share on other sites

scoot spanker 9 Posted December 26, 2009 Report Share Posted December 26, 2009 I assume it'd be the standard 180 figure Link to post Share on other sites
Rikki 2 Posted December 26, 2009 Report Share Posted December 26, 2009 Or it could be the standard 174!!! it would be nice to know an actual before and after tho????? Link to post Share on other sites
davee 0 Posted December 27, 2009 Author Report Share Posted December 27, 2009 have to say after getting a decat and stainless system the difference is very noticiblepulls alot quicker feels like teres more power lower down the revs the exhaust sounds awesumeespecially when ye drop down and give it a bit cant wait to fit the 6 branch should get a nice engine note from it Link to post Share on other sites
