I'm about to purchase a J-pipe but wasn't to sure which one to buy. I just wanted so feedback on the XLR8 and the ATLP?
Thanks...

 

Go for the latest and greatest; RV6 V3 J-pipe.

Read about it, and then make your own decision.

I agree with justnspace. It is the best one for the TL and it is ok to have on a lowered car like mine. It is the j-pipe that I want.

 

+1 and on top of that is has the best clearance and best overall gains when completed with the full system.

 

RV6 has a good jpipe if you don't care about being catless when you do the PCDs or having to go through the trouble of welding in another high flow cat to reduce rasp / discoloration / smell.

XLR8 has some good products. I'll probably end up with RV6 PCDs and the XLR8 jpipe. If you look at the dyno chart gains they're both basically the same. And honestly, on an NA setup you're not going to notice a huge difference with a catless setup vs. one cat.

 

Thanks... If i get the RV6 j-Pipe can i fit on a XLR8 exhaust? i wanted the dual pipe look.

 

I'm not gonna read that whole thread and perhaps this was already corrected, but the dyno numbers in the first post don't make any sense.

For both WHP and Torque the AVG gain is greater than the PEAK gain. How is that even possible? An AVG is always somewhere between the min and the max; cannot be more than the max.

It may be mis-labled or corrected later in the thread.

The two links below are outdated. RV6 V3 was not on the market yet when these two threads were ongoing. But, I am posting them in case the links might be helpful to you. Also, the links below do discuss the theory upon which the RV6 V3 was designed (longer primary pipes).

i dont know which jpipe to go with... (click here)

 

We saw some significant double digit gains on our j-pipe in the low to mid-range. Look at the graph comparison in these two dyno graphs; down low we were seeing a 20-25wtq gain.

Also our j-pipe is made out of T304 stainless steel, one of the highest grade stainless steels available, and it is made in the US.

 

I have RV6 V3, no complaints here. really good gains of 15whp peak.
