355 cats

Wow!! It looks killer!

Well the dimensions would include mouting points in relation to inlet/exhaust locations. Too difficult over email and such.

How much lighter was the capristo vs the stock?

 

True! But that is why I wanted to buy one. So that my car will not "undriveable" for any amount of time . I will keep looking on ebay. Congrats on your screaming system!!

 

Makes sense since the 355 isn't down all that much on power from a 360. You may have picked up a few HPs with cats. I know my car is completely different with test pipe as opposed to cat in place. What a difference in size by the way.... you'll soon have a new respect for your car now that you've modded it! Congrats it looks sweet!

 

Quick question, why in the world would CATs be going bad on a car with only 7800 miles on it?

 

They are Italian (made by Ansa) and the ceramic cores are not secured very well within the stainless steel casing. The core comes loose, rattles around inside until it starts to crumble apart. Both of mine were previously replaced at round 24k miles, and I recently had the right side go at 41k miles. Wasn't too bad; core was loose, but not crumbled yet...but it was bad enough to throw a CE light. Also the pre-cat O2 sensor had a bad heater. I was able to find two excellent, used (14k miles) 355 cats from another F-chatter for a great price and got my car fixed fast and inexpensively. I will eventually have my bad right side one, fixed at http://www.millercat.com/index.html Brian Crall (Rifledriver) has told me these guys can do a great job cutting open an Ansa cat and installing a new core, and it will work fine. I believe they only charge around $400 or so.

 

I seriously doubt it will help much. The real problem is too thin, and incorrect material for the exhaust manifolds. Don't forget that one other option is QV London. They have an exchange program and will send you a rebuilt set for around 900 pounds, plus deposit. They replace all the tubes with a higher grade ss and one gauge thicker. They retain a stock look as they reinstall the original heatsheilds. They also install the CO test ports too, which many aftermarket exhaust manifolds omit.

 

Don't do header repairs anymore, I was using the guy for repairs that did the fabrication and we can't keep up with the regular headers so it didn't make sense to compete with QV (especially since they do an amazing job) while hurting the market I was originally trying to focus on.

Gothspeed, try www.specializeditalianrecycling.com or www.ferraripartsexchange.com and see what they have for a stock muffler. They may have one slightly damaged you can get cheap. I will let you know if I end up with one. Customers leave them periodically. I have a 360 stock exhaust if you are interested.

 

I found my right cat totally empty and the left with a large chunk that just is breaking apart. I had heard the sound of a heat shield rattle and decided to upgrade to hyperflows and the X-Ost just to take care of the potential. When I disassembled everything to remove the muffler and cats I found after removing the empty right hand cat that the inner axle boot has failed. These inner boots are very close to the cats. Their close proximaty and the high heat of a failing cat contributes to the boot failure problem.
