No offense, but the conventional wisdom is that the G-Tech is junk.
That said, with exhaust only dyno's show ~10 - 12 WHP gained. Add a J-pipe to that and another ~10 - 12 WHP gained.
No exhaust with J-Pipe, I'd guess ~1/2 the gains. Just a guess.
For maximum impact you need both. And I don't think it matters which one; choose what you like for finish, cost, design, etc.

My understanding is that the G-tech may not be accurate compared to numbers generated by an actual dyno, but is fairly accurate in demonstrating changes run to run with the same device in the same vehicle. That being said:
1/4 mile stock 15.21 @
1/4 mile stock 15.21 @

For me, it will come down to how cheap do I feel like being on that day, if I buy it.

The j-pipes are not the same. I can't speak for anyone else b/c I'm not sure on the specs but the XLR8 j-pipe is made with T304 stainless steel and it is 100% stainless steel. It is an equal length j-pipe with a 2.5" collector to provide maximum flow. Yes, it sits lower but we did that in order not to sacrifice hp. The XLR8 j-pipe is also manufactured in the USA and we used the highest quality components.

According to RV6's site their j-pipe produced 5 whp and 7 ft lbs of tq. According to ATLP's website their j-pipe produced 7 whp and 14 ft lbs of tq. The XLR8 J-pipe produced 8 whp and 16 ft lbs of tq.

OK, here is a thought. Look at the place where the two pipes are welded together. If you will.
This is where the hot gasses from the engine meet and are mixed. One of these manufacturers pipes is a long tapered affair. That (to me) is the only way to get MAX hp. Also you will get the best mixing of the exhaust and scavenging from the other cylinder bank. All else being equal. I think and bought the only best made/engineered pipe on the market! And it's the least expensive. Look at all of the pipes and see for yourself. OK?

Hmm i like XLR8, and ALTP most. The RV-6 ppl had problems with exhuast leaking, that caused the hissing. If ur car is lowerd go for XLR8, if it isn't lowerd go for ALTP//

Last night I took the car for some fun, otherwise it just sits in the garage till the winter is over.
I was on second gear boosting up to 6500rpm and I heard "boom"sound from the rear mufflers. Could that be indication of an exhaust restriction? The only mode I have is the mid muffler delete.

The hissing problem was a small batch of faulty flex pipes from what I've read. Richie has since taken care of this and done right with the people that were affected. I don't have the RV6 pipe so I'm not biased towards it. Just don't feel it's right for people to read your post and get the wrong impression. Hope this clears things up a little.

There is probably some vague law that states any aftermarket exhaust modifications is illegal. But, Midas, ect is considered aftermarket, and they operate just fine. Nothing to worry about. There isn't even a cat in the J-pipe.

Just to let you know those numbers you are quoting dyno are from automatic Accord dynos. The Accord has a smaller 3.0 engine and a transmission with more drivetrain loss. I am pretty sure the ATLP and XLR8 dynos were done on TLs with manual transmissions. Quoting those numbers is simply misleading. I have yet to do any testing on the TL but I plan on having dynos done when it gets a little warmer.

The car ships with a J-Pipe (Acura calls it an "A-Pipe" or "Pipe A"), so how can having one be illegal?
It's either the "all exahaust modifications are illegal" or a misunderstanding thinking you are messing with the Catalytic Converters (which I *think* is a Federal Offense).
Are those #'s your quoting strictly from the J-pipe? Or were there other mods installed on the test cars? That is very mis-leading. I planned to purchase either the XLR8 or the ALTP soon. However, my choice could be swayed toward the ALTP because of inaccurate #'s I feel are to sway people to buy your products. You have been very good to me in the past, just want a clarification on those #'s... thanks Josh

Make your decision based on other factors: Credibility, Build Style and Quality, Cost, Personal Preference, etc.
