Ok. I drop off next week at the exhaust shop. I think I'll go catless.

 

Now would 2.75" be quieter and still ok for 600-650whp?

 

Is no body worried about CEL, Turbo issues, or loss off torque??

 

Cel can be tuned out from a flash. You'll actually gain torque because the turbos will spool quicker/earlier. Never heard of any turbo issues going catless.

 

My friend just gave me a set of these, I'm going to pull my cats off and swap them on. I'll report back...

 

Did you say you had 100 cell cats now on their??

 

I don't remember what cell they are, I'll have to look back through some old posts. I think Neil Switzer may have said what they make.

 

Between a delete pipe and 200 cell there should be a noticeable spool up difference and midrange...Not as much if they were a 100 cell....Depending on muffler internals the cat delete can make for more top end power also??

 

forgive my lack of knowledge...I have a RUF tune as I have 550 package...even though I already have tune..if I went catless and changed out my RUF exhaust...can I have local shop go in and shut off cel?

 

There's a local tuner in Calgary that can shut that off for you

 

I notice a difference - my car spools instantly w/o cats and has instant power even part throttle at low RPM in high gears. (SpeedTech 3" X-flow) Turbo cars need to breathe - the less restriction the better performance.

 

Can you give me their name and number if possible (tuner in Calgary), I have Fabspeed Gen 1 with no cats, sounds great, no smell, but I get CEL, I usually unhook battery power and CEL goes away for few weeks ,but comes on again.

 

Then did you go from 200 cell to No cats??

 

Hs name is Miguel. Company is called ecuprogram I think. Great guy.

 

Sabie if you don't have a flash on your car yet I recommend going through one of the tuners here in the U.S. you don't need a shop to flash your car for you. Save some money and do it yourself its easy. I use EPL for my tuning and I am very happy with performance, price, and customer service that they provide. Talk to Tony or Rich they'll send you a flash cable which plugs into your USB of your laptop and obd2 port in your car follow the instructions and you'll have a monster in 20 mins or less all from the comfort of your home/garage. Just make sure you have a strong wifi connection to your laptop and your good to go.
