I'm planning on getting some test pipes soon. I've done lots of reading, I just wanted to know will the rasp be really bad with stock exhaust? which test pipes ..non/res give the best gains in your opinion...thanks

 

i have that setup and yes you will have raspy sound in the mid range and maybe youl get an ses light
overall i would not recomend it

 

non-res: lots of rasp. res: less rasp. with both, you get lots of gas odor. if you have an 05, you'll prolly get a cel.

 

The consensus is that the non-resonated test pipes with a stock exhaust is pretty much unbearable.

Resonated test pipes or simply gutting your cats is preferable. I just happened to order a set of resonated test pipes from ebay that should be delivered today and installed with my stock exhaust this weekend.

Pics and review to come Saturday

Edit: Also, to avoid a CEL, search for the Help! or "non-fouler" method. It's what I'll be trying on my 05'.

 

I have Helix test pipes but then right after them i bought an altered atmosphere Y-pipe and now i have NO rasp at all and it sounds almost stock only much meaner and deeper.

 

all this "rasp" is overrated im running a straigt system xerd pipes gruppe-s ypipe and 3in HKS single and it sounds great and all the rasp makes it sound exotic i loveee the snake rattle that you get on decel

 

if i was to drive by a cop with non-resonated test pipes... would he know what the hell is going on and yank me over with a ticket?
