rich, unburnt fuel that leaves soot on your bumper ftw!

I do see some decent sized black clouds coming out at 9k shifts but Ive never noticed any on my bumper

I've used both Testpipes and Highflow Cats... There is a slight power drop with the HFC, but the smell is significantly lower... If you live in CA, I would get a HFC...

I would also appreciate some info for the 06+ TP w/CEL fix.

if you get a tp and your cel comes on, can that void your warranty for the car? i've been wondering about modifications and voiding that warranty

The Stealership would find any reason to void the Warranty with any type modification IMO. That's just what they do.


Question with people with TP - I just installed my Invidia 63MM with the anti -fouler and cut out the sound resonator and replaced it with stainless steel piping. I have a DC ceramic coated Header. How much HP, if any, do you think I gained? I was thinking maybe between 5 and 10HP...

^5 or 10 I would guess I would think you could get another 5 or 10 from a decent single catback

Have an 08 CR with 1500 miles and had a Megan TP with cel fix since 20 miles on car. No cel light. Also removed muffler before the "Y" pipes. No smell, little soot and runs great. You can hear me coming when I get on it though. Like that is a bad thing.
