Hello,

I placed an order for the Helix Cat-Delete Test Pipes, but it is a back order. So, can anyone suggest good test pipe without the cats for me please.

 

Besides being resonated or not, and piping diameter, is there a difference between one test pipe from another?
Megan Racing makes resonated test pipes for the Z... should fit the G.

 

There IS however a difference in craftsmanship. The megan test pipes are known to crack because they dont have any supports. IMO the best test pipes are the Labree resonated testpipes. They are kind of expensive but everyone that has them says its worth it. Personally i plan on getting a set of APS 2.5" test pipes.

You know what, I think that i would go with APS since I plan to install APS TT. But where can i buy this test pipe from, I went to their site but couldn't find anything.

Could you please give me the link if you have it.

 

do you think the APS 3.5" Test Pipes would fit on my injen exhaust since the injen is 2.5".

 

Do the Labree's have a rasp like the others?

 

I havent heard of the Labree's having rasp. A lot of the guys over on my350Z.com have them and like them alot. The APS 3.5" test pipes are only for the APS TT. There would be no point in getting the 2.5" then going TT because you'll end up getting the 3.5" anyways.

You can get the APS test pipes at www.performancenissanparts.com
