Downpipe options sport cat

I want to add more sound and more HP to my car, but I'm afraid of the CEL light and i would like some options.

I heard fabspeed will be the safer route but 1350 it's kinda step vs 300 for a plain D P.


Please let me know what you think and how I can prevent or avoid the cel light.

Thanks forum

I currently have fabspeed and had no issues with it but I see other brands making a similar 200 cell DP but curious to know if they all sound the same or very similar.

I am also running the Fabspeed sport cat...I went with the 200 cell, you can special order different cell counts ie 300; but it sounds like you are gonna love the 200...for sure a bump in hp/tq...and substantial increase in both volume and tone of exhaust note...I got the ASD delete so now I listen to the free breathing engine au natural....saweeeeet!!!!!

no cel...and fits like a glove...

I've got a Fabspeed 200 cell sport cat and I love it. 0 issues. Worth the price of entry in my opinion.

You'd spend the same amount of money on a DP + whatever product (tune or gauge) you'd use to delete the CEL so it's really not any more expensive then the alternatives.

Plus there's no smoke or smells to deal with. It really is the best option I think. Just pony up the cash. You won't regret it.

I'm a big fan of the Fabspeed catted DP. Adds a very nice sound with the stock exhaust and gives you some power\torque too (that you can really feel). It's well made and no CEL or stink. If you're pretty handy you can install yourself. If not it's not too much $ @ a shop.

I'd just ensure that the jig problem that caused some misaligned brackets is a closed issue. A couple of those made it to customers and it was off by about an inch.

Check the tuning forum here for a ton of info on this piece and plenty of advice on installation.

1 year in on my Fabspeed catted DP. No stink, no smoke, no CEL. Just miles and miles of killer sound and extra power. Best mod I've done to the car. Cough up the dough and enjoy.

Fabspeed also uses the top notch HJS catalytic converter. This factors into the high cost.

I too having been looking at downpipes, and do not want a CEL to pop up either. I will likely put a tune on the car after the warranty has elapsed, but not at the present time. My research suggests that downpipes built using HJS catalytic converters are the way to go if avoiding a CEL is a priority.

There are at least four downpipes readily available in the US that employ HJS catalytic converters:

1. Fabspeed 200-cpsi ($1395)
2. HJS 300-cpsi ($1495)
3. Akrapovic 300-cpsi ($1850)
4. Supersprint 100/200-cspi ($2432–$2822)

Given that I have the M-performance exhaust, which is already pretty loud with the valves open, I am leaning towards the HJS downpipe over the Fabspeed unit.

Does anyone have the fabspeed downpipe and M performance exhaust set up. How much louder did it get once you added the fabspeed downpipe?

Fabspeed 100% chance of no CEL

Wagner Tuning 90% chance of no CEL

Or you can run Bootmod3 with any downpipes and it will suppress the CEL

It's going to get A LOT louder with a sport cat regardless of what exhaust you have, but you can always drive in comfort with the valves shut if you need it quieter. Cruising on the highway there will be some drone though around 3000rpm. Plenty of people with the MPE and a DP will attest to that. Cold starts are also brutally loud and there's no way around that unless you get a tune that removes the warm up procedure. If this is your DD and you have a newborn at home or live in close proximity to neighbors that hate noise I would reconsider. If this is a weekend car and no one around you minds noise I say go for it.

The Fabspeed 200cell DP is fantastic. Expensive but worth it. I think the sound from a catted DP is better and more exotic than other options.
