hello folks, just was wondering a few things.
1. there are 2 sets of catalytic converters on the 2011 35i, right? 2. will anything happen if i delete one set? 3. which mods are recommended to have installed before installing a meth kit? thanks for reading, any info is greatly appreciated!!! -bob |

2 - I have deleted the rear ones, the sound has changed quite well but dont feel any power gains.. if you purhcase the dp without cats , you would see much better performance gains and throtier exhaust note, not raspy at all. 3 - I think before jumping into a meth system, you should get the air intake, dp, tune and new intercooler / the one that we have is very tiny comparing to aftermarket ones.. |
