I'm looking for some feedback on Roush vs what you get with Troyer stage 1:

Catback: Roush legal vs Roush off-road vs Magnaflow

Intake: Roush Cold Air vs AF1 3" vs AF1 3.5"

I realize the 3.5" would need to be switched back to stock before taking my truck to the dealer ('07 FX4 supercab, by the way), but what about everything else---
Roush seems to claim more power gain than the AF1, what about sound quality/volume level/power gains and losses through the spectrum for the exhaust?

Thanks, All.


Edit: what about the following: Roush exhaust + s&b cold air + Hypertech III ? It would save a few hundred dollars, but how much power would I really be using and would I be risking running lean? The hypertech has a canned "yes/no" for aftermarket cold air.

 

roush is a rebadged airraid,which is proven time and time again to put out lower numbers than an af1

 

There are quite a few people gettting around 255-260 RWHP and 300+ RWTQ with the Troyer Stage 1 kit. IMO those numbers are definitely worth the money.

 

What does the Magnaflow sound like? It's almost impossible to beat the sound of the Roush exhaust!

 

Thanks, guys. I think I am on board for a Roush Legal system with a Troyer custom tune. What about the s&b-to-AF1 comparison?

 

How much do the Roush systems go for?

 

Both are good, I'd go AF1.

 

Dont hesitate to get the Roush offroad, it wont be too loud. You will love it. I run mine with thier intake. that is a re badged airraid. Im sure I could pick up a litle more power from another make or model but I like the whole Roush package to flow together . I run Roush wheels as well (20's till I can get the 22's) The sound is great! And rather than beeping the horn to get someones eye, just hit neutral and squish the skinny pedal . They will look up!
