chilly Posted July 26, 2007 Share Posted July 26, 2007 I had my 2nd Cat removed today at Envy. Jesus is it loud when dropping the right foot!! It sounds really throaty and burbles nicely on idle. Link to comment Share on other sites More sharing options...
SuperSupraNA Posted July 27, 2007 Share Posted July 27, 2007 Yeah I've got a double decat, not too loud, and no noise at all once its warm and idle, which is good imo. Colby resonators work well Link to comment Share on other sites More sharing options...

Missile Posted July 27, 2007 Share Posted July 27, 2007 Thought the N/A performed better with one of the two cats left on. Can't remember which one. Was told that by a trader down bristol way. suprastore i think. Any ideas ? Link to comment Share on other sites More sharing options...
hoff Posted July 27, 2007 Share Posted July 27, 2007 Its a myth, apparantly. I'll still have my 1st in. That will be gone soon also so I'll let you know. Link to comment Share on other sites More sharing options...
chilly Posted July 27, 2007 Author Share Posted July 27, 2007 Thought the N/A performed better with one of the two cats left on. Can't remember which one. Was told that by a trader down bristol way. suprastore i think. Any ideas ? It does feel a bit more responsive, but that could be mind games with the extra noise. The 1st Cat is shagged on mine, so I won't know the full benefit until I replace that. Having looked at previous threads on decatting an n/a there seems to be very limited gains. The reason I replaced mine was cos the 2nd cat was knackered and a decat was the cheaper option. Maybe some Techy member might have more of an idea of any gains?

hoff Posted July 27, 2007 Share Posted July 27, 2007 If it does lose anything I doubt it'll be noticable. And the added noise will compansate:) Link to comment Share on other sites More sharing options...
