I just recently installed a Tsudo N1 axleback a week ago and my friend said one of the spring bolts sat funny so I might have an exhaust leak.. how can I tell if I do? And will it make a difference in how loud it will be and performance?

 

as a past tsudo exhaust user, the tsudo exhausts have some leaking problems. I drive a 09 tC and even speed-element warned me that there would be some fitment issues. I had to take it to a shop to cut and weld the axleback to make it fit. You could notice the leak by just looking at it under ur car. Check the gasket and see if it surrounds the midpipe and axleback evenly.
Now to notice it by sound, it's pretty hard to tell. Just check it under ur car and if you still think there are issues, best way is to take it to a shop.

 

i always check my exhuast leaks via sound, look and feel....


i listen for where it could come from then i look for any soot deposits...and then last i put my hand around any part where the exhaust coul leak and if u feel air at a cold start then "LEAK"

 

I have the Tsudo as well and I have minor leaks but nothing serious. It doesn't affect the performance though.

 

i got under the car yesterday and it looks like there IS a bit of space, but not much. i thought the sound got quieter since i installed it but maybe i was just being paranoid haha or i got used to it
