Some may recall a few posts a while back about my crap exhaust, and how when i first got my Z "to pass inspection" they put 2 giant cats in an odd looking place and they keep scraping on everything everywhere i go. i found a place that will cut them off and put a straight pipe in their place. would it be better to just go with test pipes?

 

perfromance wise yes. although if your still worried about inspection jsut go with high flow cats

 

it has hi flow cats, but they scrape everything.

Buy the test pipes with hi-flow cats from Specialty Z. That's what I have. They fit great. They look and sound even better. Yes, they're a bit pricey, but you get what you pay for.

 

what about the flew joints? arent they a good thing to have around? theyre there now right? would it be a good idea to get rid of them. i dont see flex jointed cat pipes on there. i see pipes, cat pipes, and flex jointed pipes.

 

The OEM exhaust doesn't have any flex pipes. Flex pipes are only necessary with something like the Iconel exhaust manifolds that Specialty Z sells. You don't need them with what you have. The new test pipes will use the factory exhaust hangers.

 

I bought the full exhaust from Specialty Z. I only had one problem and that's that it started smoking. I talked to my mechanic and he suggested re-inserting the stock cats. It fixed the problem. The great thing about the Specialty Z exhaust is that it's completely interchangeable with the stock exhaust.

 

That's good info.

 

...unless you have a 96. Nissan reversed the output flange on the stock cats, so the cat backs have to be rewelded. *he sighs*

Note - it violates federal regulations to sell a car with emission controls if they are removed. I suggest that you keep your cats and REPLACE them so you can restore the car back to a emission-equipped level should you decide to dispatch with your car.

(Just kuz I'm paranoid, doesn't mean they aren't out to get me! )

 

They ARE out to get you..........
