Can anyone help me. I want to by a catback exhaust, which i will do in december. but i am think about getting a test pipe for now. what difference will a test pipe make if any. should i buy two. one for each cat convertor.

 

one test pipe is all you're gonna need... and by you asking that question you have made it obvious to everyone you haven't done your homework. how are you gonna slap on a test pipe and not even know what it does, where it goes, or whatever.

do a little research on a test pipe, send RRM and e-mail (cuz im sure thats wher eyou saw it) and then you will be filled with knowledge and not have to rely on peoples opinions when moding your ride.

 

That and the first cat is an integrated part of the stock exhaust manifold/down pipe. You wouldn't be able to replace it anyways...

 

Why buy the test pipe if your gonna turn around and buy a complete exhaust

 

Because an exhaust (say Buschur seeing as it's the only whole one besides VRS which seems to eliminate every single hinderance) won't get rid of the cat.

 

paul, do you wanna draw this man a diagram or should i?

EDIT: we all posted at the same time.. hmm, ignore the diagram comment then.

 

ohhhhhhhhhhhh.

 

What does the RRM test pipe sound like? any one have it on?
Does it sound like a car with a cat removed and gets really loud or something else?

 

why dont you guys do it the easy way and hollow the f'er!!

 

Because I need to keep the stock one as is, so that I can swap out and pass emissions.

 

no cat makes it real loud but if you want to gains get used to it

 

Does anyone have a pic of the under side of the car like a before and after. I am at work right now so I cant lift my car up and look.

 

don't have those pics, but here goes.

please excuse the ****ty lazy pics. Please no one hollow out their cats. That is plain stupid. the test pipe is only 70 bucks, weighs less than the standard converter, and you still have the converter intact for emissions time. Just makes sense. I think it's a great buy for 70 bucks, I noticed a longer chirp in tires when shifting to second. (more torque probably) and the engine note did increase but not significantly

 

I just took a pic of my test pipe under the car...check it out on my car profile....listed below...too lazy to put up hyperlink
