scotty435 296 Report post Posted February 13 Can anyone confirm if the deletion of the 3rd cat on a NA Evora worth the effort and where is the best place to get the replacement pipe ? Quote Share this post Link to post Share on other sites
Del Lardo 96 Report post Posted February 14 By all accounts it does make a difference as it removes some unneeded restriction but I did mine same time as backbox so hard to quantify. I think I have one knocking around in the garage if the new owner doesn't want it. Yours for postage cost and a few £ in a charity tin of your choice if you want me to check? 3 Quote Share this post Link to post Share on other sites

andyj007 305 Report post Posted February 25 ive just done mine this weekend... i have the sport back box already.. noticeable difference (better) if i didnt have the sports back box already i woud have got the tubular back box with the decat pipe in place , that sounds really good. (Although £800) this still keepe the the front two decat pipes.. i heard this on @m6arks car at the weekend.. it straight forward enough but i had to grind off 4 diffuser bolts due to the hex heads rounding off.. 1 Quote Share this post Link to post Share on other sites
electro_boy 77 Report post Posted February 25 I'd say 3rd cat deletion is worth it. I've been to a couple meet ups and my Evora seemed to sound a bit louder and have more crackles in the overrun than some other cars. As far as I was aware I had the standard sports exhaust on my car but found out on the weekend when I had my diffuser off that the cat was missing and replaced with a straight pipe. I guess this is the reason my car sounds different to other NA cars? 1 Quote Share this post Link to post Share on other sites
