Can someone please help me decide with test pipe to buy off of ebay, if any. link
Are they worth buying or should I just save my money? Thanks.

 

Spend a little more and get one off this forum, like a berk or a megan (the berk wont trip your cel and the megan has a small resonator.

 

Cant find it one the fourms. Please help.

 

here is berks ### 949-6798618

 

Go into the sponsored group buys. Should see the Berk, its awesome. Also, everyone loves their megan test pipe also. Cant go wrong with either, both cheap!

 

Got Megan Racing SS test pipe,resonated,and it.
And no CEL,with the antifoulers plugs.

 

I know this is probably a stupid question but is there much of a performance difference with the test pipe?

 

I'm assuming you're questioning whether there're difference between different test pipes?

I have no experience with the S, but on my miata yes difference in test pipe design did make a difference in performance. Since I did my own welding, I'd been thru' a few revisions of test pipes for my miata for track use. Besides the obvious requirement of smooth and matching piping diameter, my last revision of "slotted" out test pipe covered by a hollowed hi-flow cat (worked more like a resonated test pipe) gained back quite significant amount of low-mid torque compare to a straight test pipe in such a way that I didn't have to rev the last rpm to get the extra oomph on the next higher gear and 1/4-mile time was faster, all the while with not drop in high-end hp. Note that each revision of my test pipe was accompanied by optimal cam timings and ECU reprogram to match. Don't know how much of this apply to the S.

 

where would I find the megan test pipe

 

Testpipes are cheap enough for brand name ones. Even though its just a piece of pipe I would rather buy one such as the berk testpipe from the group buy forum and support the sponsors of s2ki or go with a T1R, etc instead of an ebay brand.
