im not sure if i should goo with the rv6 v2 or the xlr8 j pipe

i see them both for around the same price, so i was wondering from people who have one, which would add more power and be more dependable, long term use wise. also is there a difference in loudness of the two ? i have 2.5 str8 piping already, so was just curious, here are the links to the 2 i was looking at. thanks for your help !

As to the choice between the two, I can't help you.

But regarding sound/performance? Same sound, with no effect on your straight-pipe exhaust setup. For performance, I'm gonna say they're very similar, but with no information to back it up.

 

thanks for your help, im still new to modding the tl i just got it a few months ago and am very interested in getting it to its top performance, just not much idea how lol

 

I've got the rv-6 V2 w/ test pipe. I am really happy with this setup even though I am w/ my stage 1 exhaust untill I get the full non res exhaust from exlr8.

 

i think im going to go with the rv6 and race pipe to. did you notice any power gain after you installed it ?

 

rv-6 all the way Richie's personal service cannot be beaten, yes gains will be felt as well as a beautiful v6 sound

 

i got rv6 v2 with test pipe, i never look back at oem. I do feel the gain and increase in mpg. Plus when i called for question, richie picked up his phone and help me with the installation.

 

Same here. I had a question, called him, he picked up, answered my question and I was happy.

 

thanks for the help im going with it i just bought mine i hope everything goes well =D

 

Just remember when installing, to loose the front pre cat delete so you can attach the
j - pipe.

 

I member when we aint had no jpipes available

dear op... search is ur freng meng

 

I recently had the same question and did some digging on our forum. Here is my conclusions -

If you are or planned to be slammed (drastically lowered), then this excludes the XLR8 as a option.

If you want to save money and mainly interested in just the peak hp number only, get Richie.

If you want the best crafted and best designed (both are just my opinions), get XLR8.

Here is the thing that made-up my mind. There are two respected Acurazine members that had tried both Richie and XLR8 pipes. Both say, hands-down, that the XLR8 made more power that was easily felt. I was sold. Here is pics of my XLR8 pipe.

 

Some people said atlp and xlr8 pipes are more free flowing but for performance to price wise there all the same

Hey innacurate wanna race on aug 1 at the nation import meet??

 

Performance wise they are not the same. Construction is different, material is different, exhaust flow is different.

 

richie v6 all day. get the whole kit

 

Atlp v2?

 

I want to clear-up what I said earlier. I rushed to make the earlier post last night before rushing to bed.

I do *not* mean to imply that Richie makes more hp. Just the opposite. I meant to say that Richie and XLR8 might be the same peak hp, but the XLR8 makes more overall hp thru the entire rpm range.

I feel that the XLR8's overall hp is far superior. Why ? Physics of scavenging. Do a Google on "exhaust scavenging" to learn more if you are interested in understanding. Richie has a free flowing design. But, there is something more important than just free flowing exhaust. For the ultimate torque production (N/A), the engine critically relies upon exhaust scavenging. The longer primary pipes of the XLR8 compared to ATLP is what produces the superior average hp ... in my opinion. Richie's design totally disregards exhaust scavenging.

If someone wants to tout how much peak hp they make, then fine, get Richie and save some bucks. However for real racing (not "dyno racing"), the average hp thru the driving rpm range is what counts. XLR8 will provide more hp thru the rpm range.

 

I don't do meets. But, I would love to do a line-up. Please send me a PM to see if we can arrange something.

 

just curious about how much HP do u actually gain from getting one of these put on your TL?

 

I was told somewhere around 10whp possibly less, but paired with a cat back exhaust were talking at least 20whp

innacurate will do going to wait on my xlr8 jpipe and exhaust

 

If/when I get a jpipe it will be the ATLP v2

 

Hey Jimmy, check this out: https://acurazine.com/forums/3g-tl-performance-parts-modifications-112/e-124-atlp-v2-vs-rv6-v2-%2Apics-comparisons%2A-737152/

 

Only in your wildest dreams...You'll be lucky to get 10whp including the cat back.

 

I can vouch for the quality of XLR8 . The product is of VERY good quality, flawless products and perfect fitment. You can't go wrong with the XLR8

 

im assuming this is pretty easy to install? i am looking to get some type of hp boost even if its very small. this looks like a good start.

 

? Not dreaming at all.

XLR8 catback alone gains 10 whp and 20whp near high rpm which is proven on there dynos.

 

The strength of the ATLP and XLR8 pipes (versus Richie) is all about the long primary pipes promoting exhaust scavenging. The strength of the ATLP and XLR8 pipes (versus Richie) is all about increased average hp, not X amount of PEAK hp improvements.

Look at this torque curve below showing the ATLP improvement. I can vouch for the graph truely representing real life improvements.

The XLR8 seems (from viewing photos) to having the longest primary pipes versus ATLP (Richie ignores this aspect). To get the longest primaires and the most exhaust scavenging effect, I choose XLR8.

 

Xlr8 jpipe and exhaust here I come

 

here's a pic of the dyno, the darker more vivid 2 lines are the J-pipe dyno posted above. The lighter lines are the before and after of the XLR8 exhaust

 

And with jpipe if I may add what's the increase? My iPhone can't read it!

 

Our j-pipe on a TL-S made 8whp and 16 ft lbs of wtq.

 

thanks for all the info i went with richie on the rv6 after reading all that kinda wondering if i made the right choice... well either way hopefully ill enjoy it thanks for all the great info

 

so w/ regards to exhaust scavenging: Is there any way for there to be optimal exhaust scavenging while keeping the j-pipe an acceptable size to not get scratched up by people who are dropped more than 1.5" ?

 

Yes. This is what ATLP Version 2 is addressing.

However, The XLR8 is made by the famous Billy Boat (http://www.bbexhaust.com). So, if you don't really need the ground clearance for lowing purposes, there is an advantage to XLR8 being made by Billy Boat... and it shows. Plus, the XLR8 has the longest primary-pipe length.

 

just want to confirm this statement about being slammed. I'm pretty low but from what im hearing XLR8 is the choice but if slammed not a good choice at all?? Thanks

 

Based on my searching of our forum, slammed (extremely low) members had severe scaping issues (however, none actually worn completely thru) with the ATLP Ver 1, and XLR8 pipes.

 

so yay or nay for slammed? leaning towards nay, i dont want my $400 piece of equipment getting damaged.

 

Nay. Get the ATLP version 2. Be sure it is ver 2, *not* ver 1.

 

how about the xlr8 on aspec suspension? will it be fine?

 

Slammed=more than 1.5" Aspec suspension is about .5" So you will be fine with XLR8.
