Martin W Posted September 18, 2009 Posted September 18, 2009 Just dropped in to one of the Big Exhaust Chains to find out where a rattling noise was coming from on the left undereside of the car. Nothing obviously loose, opinion seemed to be its the passenger side Cat on the way out! Can anyone tell me if they've had this happen, how would you describe the sound? The car has just done 33,000 so doesn't seem too bad. How long do they normally reckon to last? Quote
dcash5 Posted September 18, 2009 Posted September 18, 2009 I think on yours martin, you'll be running alot more heat than a stock NA system because of the turbo's so life would be significantly shortened Ps you have posted this in the 370z part Quote
Martin W Posted September 18, 2009 Author Posted September 18, 2009 Oops! maybe a mod could move it. Anyway, already been over to A little outlet near me and picked up a set of Berk's Cheers Sarah Now to find someone to fit them...... Quote
Stew Posted September 18, 2009 Posted September 18, 2009 Will you need the mapping adjusted with the freer flowing exhaust in place? With it being a turbo I wonder how much difference the sports cat would make. Quote
Martin W Posted September 18, 2009 Author Posted September 18, 2009 Will you need the mapping adjusted with the freer flowing exhaust in place? With it being a turbo I wonder how much difference the sports cat would make. I'm not after more Power really Stew. I spoke to Mark at Abbey a couple of months ago about a few things, and anything that helps heat dissipate can only help. Its interesting that I lost the Drivers side Cat at about 25,000 miles prior to going FI. The pax side one lasted another 8,000 after conversion. So i don't really think FI is relevant. I'm just curious how long other peoples last. It bmight be more relevant that I only have a 7 mile commute each way, so the engine isn't really ever warming up I also note that APS insist on a True Dual exhaust to maintain the warranty. But they do not insist on Decats/ Hi flows which could net them a few ponies more. I had a Ford where the cat went at 25k, I'm curious at what mileage other people have had to change.? Quote

I wasn't sure how the mapping changed with increase of flow rather than tuning for outright power... I have no knowledge of FI really so was curious. I hit 53k on the hoon and I'm unsure if my car has had cats done or not. My landie cat failed at 82k though! Quote

I'm on 76k, stock cats, going in for MOT this week. Andy (CS mechanic) said they were in v. good condition for their age! Fingers crossed they pass! Quote
ZMANALEX Posted September 20, 2009 Posted September 20, 2009 I think that you have just been unlucky with your cats Martin. Quote
rtbiscuit Posted September 20, 2009 Posted September 20, 2009 first case i've heard of them failing. might go the sports cat route at some point. just don't want any raspy-ness. Quote
Martin W Posted September 20, 2009 Author Posted September 20, 2009 I think that you have just been unlucky with your cats Martin. Does seem like it. Still, will be nice to see what difference to the sound the Berk's make Quote
Adriank Posted September 22, 2009 Posted September 22, 2009 Get TGM to fit them, they have experience now having done my decats/ sports cats a few times... Quote
Martin W Posted September 23, 2009 Author Posted September 23, 2009 Get TGM to fit them, they have experience now having done my decats/ sports cats a few times... Already booked in at Abbey - Saturday for a few things ! Quote
Chris`I Posted September 23, 2009 Posted September 23, 2009 Get TGM to fit them, they have experience now having done my decats/ sports cats a few times... A few times? Think its a bit more than that now isnt it? Just got the call that my car passed the MOT, stock cats ok @ 76k miles. Think Martin has been unlucky, but what a good excuse to get Berks Quote
Martin W Posted September 23, 2009 Author Posted September 23, 2009 Funnily enough, no noise this week!!!! Too late Quote
