has anybody run a test pipe on a stock ls exhaust? does it affect the tone of the exhaust?

 

i had a konig rear section, on when i did the test pipe, so i cant say for sure but it would have to make it louder, even with stock muff. only prob i had with test pipe was a hella stinch, when pulling to a stop the gas fumes would come back around the pass. side and about gag you, hince the word test pipe, i couldn't stand it on the street daily, but it did make a lot of difference than stock cat.

 

so does it gain hp ...and sound???i want to et one for my b16a tef with stock exhaust????would it sound better???????

 

not worth it if you're in cali. if you get caught with a test pipe, you get fined. and your car would end up smelling like shit and it would be annoyingly loud.

 

does stink but seems to make a hell of difference, never ran on the track and yea not worth the fine, but as long as you have a muffler of some kind it shouldn't be to loud, my konig muf. with test pipe was pretty loud but not obnoxiously loud.

 

im asking this question beacuse im buying one from this guy and i just wanted to see.....so how much hp does it gain...and is it really that loud with stock exhaust??? how much can they fined me?????

 

not sure on the fine, since you're in cali, expect something that'll empty your pockets. as for the power, i'd guess about 2-4 hp, if that. and you could prolly make one yourself if you had the resources.

 

i have a test pipe with a tanabe srm exhaust and its a little too loud

 

i asked that because i live in valley center and over here cops dnt care much cause theres a lot of trucks over her that disconect their exhaust systems from the cat out..and stuff and copss dont care?????

 

yea the only time i have any problems at all on the east coast is when inspection/emission time rolls around, but you can usually buy one easier than you can make one, i am a fabricator but didn't wont to come up with the mounting flanges due to the ball/socket gasket coming off the header, and here i have a contact at a junk yard and he wont even sell me a convertor just for the flanges? you can however gut out your stock one and do the same as a test pipe, but of course you have to have a back up plan just in case
