hey

i've been looking around at different exhausts cat back and im stuck is there really any difference between diff brand twin 2.5" ones? im looking at a berklee atm, and they "claim" to be the best

They all "claim" to be the best. That is why you need to speak to someone who has done the R&D... i.e. Craig at ACE.

ye im planing on going down once i get a day off work. just that there's a berklee one on ebay which is pretty cheap and ends in a few hours, just wondering if they were pretty much the same as the rest
