Fast Intentions exhaust is here!

wstar · 06-02-2011, 03:17 PM

Assuming nothing came loose, (and forgive me if this seems obvious, but I never know what people already know around here), did you line everything up before torquing everything on the install? With things like this, I always bolt everything together loosely first and get it lined up perfectly, and then snug all the bolts in the system at the same time. If you instead torque everything down as you go while installing the bits, things tend to not sit right.

This is what they do at F.I. as well when installing it. Checking to make sure everything is level before the final snugging.

Hey, it was done by a shop that works on a lot of subaru's and mitsubishi's, they know their stuff. Its weird, i didnt notice it before. but i definitely notice it now. I just measured the two and the passenger side sits a 1/4 inch lower from tip to bumper. Here is a pic... i just feel like if i shim the driver side it looks like it sits too far from the bumper... maybe im just being picky...

Be careful it's not too close. Mine sit about 0.3 - 0.4cm from the bumper (as measured with a caliper, one is a little lower than the other), and over time they've very slightly melted/scorched the underside surface of the bumper in a tiny spot. You can't see it from the rear so I could care less, just FYI. The only reason mine are so close is because I had some tip clearance problems due to (we believe) the output location of the Stillen short-tube headers that are currently on the car. I used washers to space off the rear hanger bolts to give even that much clearance.

Honestly from the pic the clearance and side-to-side difference looks pretty normal to me. Maybe if it were up closer or if I could move side to side and stare at the angles in realtime, I'd notice, but I donno.

Yea its hard to tell by the pic. at this point i think ive just been starring at it for too long and my eyes are playing tricks on me haha.

Sorry to blow the thread up, but i have another question for people who have the hfc's and exhaust. I notice a little "sputter" when coming off the gas pedal. wanted to make sure this was normal. Was wondering if thats the small bit of "rasp" i hear about. Thanks for everyones help with everything..

Anyone have any feedback on this? The noise is like a Sputter or almost like a backfire noise... Does it also when the Syncrorev match is on and it revs high quickly and i let off the gas...

This sound is perfectly fine. It's just a flutter from backpressure I believe. Ever heard an SRT4 when they let off the gas coming up to a stoplight and it literally sounds like the car is gurggling? It's kinda the same as that, only more muffled.
