I don't know why you'd even bother going with FI if you're just going to murder the mufflers.

The "best" solution if you have to modify the system would be to mount the existing cans horizontally in the factory muffler location and fab some new pipes. This will obviously change the sound a bit and might hurt performance, but it would at least salvage most of the system.

I would give Tony a call and see what he thinks your best option is.

I could get sued or taken to court if anyone got hurt or injured (ie handicap electric chair)..

Hahaha :D well lemme think of something.

Here you go.

Actually, Im keeping the FI muffler pieces in tact.
Muffler shop is going to make new flanges and pipes to their own cannisters similiar to the layout of the FI system. It will offer better clearance due to it being smaller cannisters and being welded/made at a different angle. That way I can always bolt the FI piece or sell as a set if I ever decide to.

The shop Im going to does great work as they make custom TI catbacks for cars with clean welds,...I thought I give them a try since I used to get my Subaru Legacy GT dyno tuned there a few times...

Well, like I was saying, that kind of defeats the purpose of FI as it's going to totally change the sound.

Anyways, post up some vids of the new custom setup so we can hear it. :tup:

just gotta do what it takes...
Its not like Im going to die if it changes the sound as doing somethingg like installing my Hi Flow cats will change the sound as well..so,...no big deal on sound change...

As long as performance is the same or better is what matters, especially if this means being a viable DD and that there will be no damage to the car...Im going to dyno tune later if COBB comes out with something or do an UpRev dyno tune..I have several places/people in mind right now..

What is the use of keeping the sound intact if your FI mufflers are hanging or left for dead in the middle of the road? :eek:

m4a1mustang 05-04-2010 10:20 PM

Well, what I really meant by keeping the sound in tact is reusing the FI mufflers. By going with an unknown you run the risk of your car sounding like crap.

Not sure if putting a more free flowing exhaust can make it sound worse. It will sound different, but sTill sound Good. I had the heiGhT adjusted so I won't be changinG The cans,...if anythinG, I'll mY pick up a different exhaust if a good deal comes around.

Amuse or Ti type exhaust comes to mind,..

TGTGGY was wondering if you were trying to spell something crypticly.

Danny3.7 05-08-2010 10:13 PM

any chance it would clear by going up (or down) the driveway at an angle?

lol,...nah,..just browsing and was typing using my new iPad....
for some reason it was using Alphas on certain letters...

And going at an angle would help, but my driveway isnt that wide...I got it all fixed tho as ride height was adjust so it wasnt slammed...I also just lowered the front 1/4" as its only the rear that had the driveway problem...

I'd just love to be in Hawaii...until I had to buy something. :D
