AngeG Member 2 Member For: 15y 9m 3d Posted 11/10/09 10:58 PM Share Posted 11/10/09 10:58 PM Hey guys, just interested if any of you guys have a 100 cell cat installed? I went to my exhaust shop and they told me not to install a 100 cell cat because it'd be way too loud, and recommended a 200 cell cat. Is this true? Will there be much power difference between the two? Im running a remus cat back exhaust.Cheers Link to comment Share on other sites More sharing options...

I've just bought a Ballistic 4.5" 100cell but only looking at up to 300rwkw at max... should I perhaps look at getting a 200cell as would be better for my application?
