Is it worth the hassle?

[ayfreetee]

I have a de-cat pipe that came with my car but not fitted, the previous owner removed it because it threw up the eml, the downpipe is standard, but it has a heat wrapped stainless tubular manifold ( don't know the origin), would it be worth fiting it with a lambda extension elbow, or are the gains too minimal to bother with, thanks.

Not worth it on a standard downpipe to be honest. Mayyyybe sound a little better

My S3 made an extra 10bhp with a decat running standard down pipe and no map tweak. Verified on RTech's rollers.

Mmm, might be worth a punt then, don't know if it helps that it's on stage one revo map.

Mine was running a prehistoric AmD map, my APY narrow band made 275 with just a decat and Badger5 3" TIP with Jetex cone filter. I had just serviced it mind, fresh plugs and oil.

Yeah I just bought an sfs 3" tip that I will be fitting, did a service a few weeks ago too, so hoping for some improvement.

I put a Decat on my standard down pipe. My car is also revo stage 1. It was noticeably louder and that was it really. Didn't notice improved throttle response or power.

As I thought, getting conflicting advice, not sure whether to fit it, or not bother now, decisions decisions.

Less restriction, more power. You will get better flow, turbo spool etc with a 3" downpipe, but the decat will help for sure!

The standard cats are a golf ball through a garden hose type situation

I say if you've already got it, fit it.

 

[ayfreetee]

Yeah, I think your right, I'll stick it on when I get a lambda extension elbow. Cheers chaps

Louder inside the car or out or both? Quieten down when warm?

Thanks.

Both, it becomes more boomy. I found the turbo spooled up quicker on my car with the decat fitted.
