I have a greddy ti cat back and a helix downpipe and i am wondering which test pipe i can run with out getting a cel. I was going to get the helix test pipe but they seem to be out of stock every where for quite a while. So any feedback or suggestions would be greatly appreciated.
Thanks,
Chris

 

You should do a search there is soooooo much on this, but since I'm nice I will tell you to spend your money on the UR test pipe. No cel and it bolts right up to any 3" system.

 

WorkS All The Way

 

The Perrin is a good one and includes a CEL fix that take 5 min to wire in.

go helix to the greddy.a testpipe is a testpipe though

 

I'd say go with the UR. Ive had mine for about 6K miles and no CEL. Not bad for $75

 

the Ultimate Racing cant be beat. For 75 bucks its a steal, and no CEL here either after almost 20K miles. Great wuality and price. Get it and be done!!

 

how come the the UR doesn't doesn't cause the CEL to come on... its not like the perrin that fakes it with the little module.. its just a pipe.. how do they do it???

 

Helix

 

Just installed my UR 2.5 Test pipe. Great product. No CEL

 

CEL fix if you do get one. Cheap and effective

Ultimate Racing! 15k+ miles, no CEL.

 

UR all the way. 5 k and no cel.

 

The UR doesnt throw a CEL because of the way it was designed. All it is, is the test pipe, no module of any kind to trick the 02 sensor. If you bought one, once you seen the pipe you'd know why it doesnt throw the CEL. Great product IMO

 

yep...and again for the price it sells for, it cannot be beat
