Replying to: aatherton (Jun 26, 2006 3:59 pm) Great---we all make good choices depending on our needs. I think the strut brace will help me...I live in a place with extreme curves on the downhills and I'm sure the front struts are flexing a bit. But not all cars respond to front strut braces in the same way,that is true.   As for the muffler, my stock xA muffler sounds like a can of gnats. I definitely would pick and choose the aftermarket muffler carefully. You can even listen to the various choice at scionlife.com before you buy. Some scion owners have thoughtfully recorded the various resonances of different mufflers!   I haven't look very closely at the turbo installations. 185 HP sounds like way too much stress on that Scion engine. Geez, what kind of boost are they running? Can you say KABOOM? I was thinking 130-135HP tops is all I'd need, with very modest boost. Replies to this message: aatherton (Jun 27, 2006 3:31 pm)

They all start up and rev in neutral, and the sound quality is poor. From that I can't tell what the sound is like under acceleration load and cruising at 65. My stock muffler is plenty loud - I would be afraid to travel with anything louder.   Over the years, I have put tasteful low restriction exhausts on two BMW 2002s, a VW Rabbit, and a couple of motorcycles. Although the sound was nice short term, after awhile it was too much and I reverted to stock.

I finally got the Progress rear sway bar on the xA (same as for the xB) and the DC Sports front strut bar and I must say the handling is much improved. "Turn in" is much quicker and I swear the ride is less bumpy. HIGHLY recommended mods and very easy to do.   The DC sport muffler? I'm undecided about whether I like it or not. Up to 65 mph it's quite pleasant but it does seem to drone a bit at 70 mph....nothing bad but perhaps over 8 hours it might get to some people.   I was thinking of buying or making a little silencer to insert in the barrel of the muffler if I take a long trip.
#228 of 317 TC Supercharger by alliej Jul 25, 2006 (2:39 pm)
Can anyone give me an idea about the mileage difference after installing the factory supercharger? Replies to this message: Mr_Shiftright (Jul 25, 2006 3:57 pm) aatherton (Jul 27, 2006 9:21 am)

Replying to: alliej (Jul 25, 2006 2:39 pm) I'd guess 10% less...it depends how much you put your foot in it. At high altitude, the mileage may not change at all.

Replying to: alliej (Jul 25, 2006 2:39 pm) The purpose of the supercharger is to force more air into the engine so a corresponding amount of additional fuel can be used, for the purpose of making more power.   If it is possible to avoid using the supercharger, there is no change in mpg. Occasional or light use of the supercharger will cause a 10% reduction in mpg. Frequent or hard use of the supercharger will drop the mpg well below 20.
#231 of 317 Rattlying noise by curious54 Jul 29, 2006 (11:26 am)
Have a 2006 Tc 5-speed manual with CAI and Header. Yesterday I was in traffic and it was stop and go. I put it in 1st gear and went about 20 feet and let go of the gas and suddenly heard a rattle. Tried it in 2nd gear and it rattled but not that loud. The thing is that when it starts to rattle and i push the clutch the rattle goes away. Anyone know what might this be.

Replying to: curious54 (Jul 29, 2006 11:26 am) The motor rocks back and forth on its rubber mounts when accelerating and decelerating. The motion is most severe in 1st gear because it has the most torque, and lessens with each higher gear.    It is likely that there is not enough clearance around either the header or the CAI that you installed, and the movement of the motor is causing one to contact the the body.   If the motor rocks forward on deceleration, the CAI could be contacting the battery or grille etc. If the motor moves rearward on deceleration, then the header could be contacting the firewall ect. The first case is more likely. When you push in the clutch, you disconnect the engine from the transmission, so there is no torque to rock the engine over, which is why the rattle stops.
#233 of 317 Modifying 06' Tc Driver's Seat (Farther back) by mss Aug 10, 2006 (11:17 am)
Does anyone out there know if it's possible to change the mounting of the front driver's seat back about one inch without too much of a hassle? Love the entire car but if I could get an extra inch on leg room, I'd be a happy camper.   Thanks!

Replying to: mss (Aug 10, 2006 11:17 am) I've been checking seat mounts on the xA and xB and it doesn't look very easy. I presume the Tc has a similar system.   The problem is re-positioning the brackets that connect to the welded supports in the floor. Once you shift the track back, nothing lines up with the floor anymore, and the track and the mounts are one piece thingies.   I think this would require removing carpets, welding supports into the floor (after all, it is your LIFE we are talking about here) and re-fabricating the seat brackets.   Certainly do-able but it doesn't look easy, at least not on the xA and xB. I had the same idea as you but I am now discouraged unless I come up with a brilliant idea.
