today after driving home from the train station it seemed my car lost torque in the low range, my exhaust got extremely louder, deeper and less poppy. i'm pretty sure i've broken in my injen since i've had it for a year w/ 10k miles. the test pipes i put on about 5k miles ago and i keep throwing fiberglass like a freakin fire extinquisher.

is it possible that:

1. the last chunk of fiberglass blew out today?
2. i have a serious leak somewhere?
3. the test pipes ruined my funked injen straight tip with the fiberglass problem?

someone chime in with this same setup (injen, helix)...thanks

 

The rear of my white Z has some black specs on it from the exhaust. Not sufficient to cause a problem. Search for a leak. If none found, and you're still not content, have a diagnostics test run.

 

most leak posts have concerns with a 'hiss'...i don't seem to have that problem

 

I got a leak today and found that the 2 y-pipe bols were a bit loose and blew out the gasket. There was no hissing noise, just MUCH louder exhaust tone and more rasp from the test pipes.

 

which exhaust system do u have?

 

JIC Y-pipe and Exhaust system.

 

drumma i was asking seanlaw. lol anyways check for a leak or maybe the test pipes have a crack in them. look for a blown gasket seal. if everything is fine then run a diagnostic test. if that says ur car is ok then i dunno....

 

thanks guys...i'm going to check all the bolts first, then check the gaskets, the check the welds on the test pipes.
