thanks for those who support me, and to those of you who spend $800 on your shiny coffee can mufflers, whens the last time you really pondered what ricey meant? Because i can pretty much gaurantee that this setup that I welded for $40 sounds one hell of a lot better than stock, and i still have an extra $760 dollars in my pocket compared to those who would put out for the high end systems... so who is being short changed here??? I still have performance, and a sound better than a mustang.

 

i'd like to see what kind of gains it's actually giving you, i highly doubt it's over 3whp.

 

even if it is only 3hp, that kind of gain for $40 makes me very pleased

 

To each his own!!! I personally prefer the trd exhaust...good sound, nice looking, more power, and that thing what was it...oh yeah the warranty...if i spend 19K on a car and void my warranty on something like that i think it is dumb... my .02

 

Not bashing at all, but what part of your warranty would you void by removing either the axle back (or the cat back for that matter)?

On a side note, how is this mod "rice"? I mean, I understand if he was putting on neon's, a big farkin' wing, a 10" tachometer, or a bunch of stickers. Lots of folks will take out their resonators, how is this any different?

 

We all have our high standards.

 

well after revving next to a mustang, it certainly was just as, if not more, throaty

 

would it be fair to say that anyone interested in the sound of this mod (as well as getting a dyno result) could achieve it by just removing the axle-back portion of the exhaust? the welded bit only serves to direct the exhaust gasses to the rear of the car (and provide a place for a pretty tip)... right?

if i'm understanding this correctly, then i'd be very interested to give it a try. since removal of the axle-back portion is reversable (it can be put back on), anyone who's b!tching about it being "ricey" sounding can just DO it and decide for themselves.

what would be interesting to do is run a dyno test with the OEM exhaust, no axle-back exhaust, and something free-flowing like a magnaflow axle-back exhaust. does the backpressure created by the muffler serve any purpose (bc sometimes it can), or is the back pressure from the cat sufficient for the tC's system?

yah, i realize this could be taken 1 more step by removing the midpipe and cat. but then you're into a seriously illegal exhaust. as long as the cat is there, the only illegality of a straight pipe could be from sound decibels.

i also give props to anyone who welds his own stuff and is brave enough to try something like this. way to go!

 

The backpressure from the stock muffler does serve a purpose, i noticed a slight decline in off the line bottom end torque, but the higher end is awesome now, pulls much harder once you hit higher revs. I also used 2 1/4 inch exhaust tubing instead of stock 2 1/8, i think the 2 1/8 would have done a better job in keeping some of the bottom end power tho, but too late now, i could just weld another one at that size tho, hmmmmm. btw it cost me much less than $40, i just returned some of the material i bought, all i needed was 2 90* bends and 2 45* bends. The exhaust flange and hangers i made myself with some barstock i had sitting around and some 1/4 inch plate we had used to re-enforce the tie downs in our trailer so we could tie down heavier bikes like harleys. So if you plan on trying this, you may want to try the stocks size for the tube, and maybe consider a larger than needed s bend to try and get some back pressure.
