I'm thinking of getting a cat back installed on my 156 V6, and don't want to pay through the nose for a Wizard system. I also don't want to create unnecessary noise boy racer style. I'd like to improve the exhaust system, and add a little more fun to the sound. So I've been looking at Longlife cat backs as they seem to be good quality and within my budget. Has anyone had any experience with them? What do they sound like?

Longlife are a collection of agents who fabricate an exhaust from pre-assembled parts. I think comparison from experience may have limited relevance.

Thanks for the clarification. I guess the question is then: are non Wizard / Raggazone cat backs worth it?

I think they may still have value. It depends on the individual and how much knowledge they have.

With a CF3, it has long been known that the pre-cats allow too much heat to the ECU which can cause irreparable damage so that is the first thing to attend to. The earlier CF2 cars have a silenced catalytic converter which really helps in producing a nice sound which is not too loud. Ive noticed that the rear flange can corrode and if so, it is worth trying to have a new flange fabricated and TIG welded on. That may be something a specialist exhaust fabricator may do but it depends on condition.

Which version do you have?

In regards to the quality of materials I have mine around about 9 years, still looks good and no issues.

The fitter did talk me through the options in regards to noise

Thanks for the details and advice. Mine is a CF3. How would I protect against the issues you've mentioned?

You referring to LongLife version? Did you notice better fuel economy or power?

With regards to the CF3 overheating the ECU, it is simply a de-cat (racing only) or conversion to CF2. There is also the kind of hybrid route that is popular with GTA owners which uses CF2 style manifolds to fit a CF3 which has a main cat in similar location to CF2 cars.

Don't expect measurable effects from a cat-back system. Differences are only measurable if manifold and cats have been changed.
