good question.. i would like to know the answer as well.

 

you can make your own;it's just apiece of pipe,diameter you like,with a flange welded at each end.
Now,tell me,wich one makes more H.P.and why.

 

They will both make the same...


because...


all any of the test pipes are is PIECES OF PIPE

 

Just Ordered Megan Header and Test Pipe... Header has good dyno numbers as it gained horsepower and torque so i decided to add the Megan Test Pipe as well. I have heard alot of happy customers with it.

 

At long last.!!!

 

But,if you stamp a big name on it,like Spoon,or J's,and the thing costs you $400.00,you'll be more prone to bragg about it,and say it makes more H.P.
You want to get your money's worth.!!!

 

You seem to be happy with yours which is another reason.. plus everyone is saying they have had no problem with it throwing a cell... i always research everything before i purchase... thats just me!

Please note that my TP experience was with my miata, which was highly modified and have a fully programmable ECU plus cam timings to tune in to maximize gain from any single mod put in the car. For the S, it is possible that you may not lose torque from a straight-thru' TP because the pre-programmed fuel is too rich for stock cat but leans out just enough for TP that it doesn't lose torque.

 

I really love my Berk Tech TP. I have put 1500 miles on it and no CEL.

 

I have a Berk and threw a code. Put the anit foulers in and not a problem since. My opinion, just buy whichever one is cheapest as it's just a pipe and I thought the built in cel fix for the berk would work, didn't work for me or my friend
