as far as sound goes which are the best test pipes... because i just bought the greddy spectrum and i can definitely hear the difference but....its just not loud enough for me. so please bestow your knowledge upon me...

and if you have the greddy spectrum plus some test pipes or some other type of upgrade to catback please send me a sound clip or something.

=)

 

All test pipes are basically the same. If u want cheap get berk or pay more for some of the name brands. I'd reccomend resonated

 

Moved to proper forum

 

haha sorry dave im kind of a noob when it comes to this forum business. all right thanks jig, duly noted.

 

Test pipes are an empty piece of pipe. They don't make any sound.

Catalytic converters are NOT noise attenuating devices. Mufflers and resonators are.

 

thats why im following jigs advice....resonated test pipes
