I don't have enough money to try ATLP so I think of ATLP J-pipe + HI flow cat. What do you think compare with ATLP J-pipe + Hi flow cat + exhaust ?

 

You might as well get the exhaust first. Doesn't make sense to get the J Pipe and HFC because you still have a resonator and mid muffler on your stock exhaust that will restrict the air flow.

 

Jpipes, next to PCDs will be your best bang for the buck, HP wise. Full exhausts are expensive and jpipes make the same if not more whp than a full exhaust.

 

Do you have a cold air intake at least?

 

I don't want a CAI because I heard that it just likes a sound box .I almost can't get the ATLP due to my credit limit is 700 ( it will take me a long time for saving). Also as I see so far, the ATLP kinda loud for me .

 

Get the RV6 V3 J-pipe and RSB.

 

I did the J-Pipe and left the stock exhaust on for a day just because i didnt have time to do the whole thing right away and you will notice a throttle difference. I would do it then when you can afford the exhaust get it.

 

Agree, I just looked at that post yesterday. That's sound too good but I have to make sure that's okay with Texas law ( no 3rd cat ) . Thanks everyone.
P.S: I keep spending money for TL without stopping point

 

Removing the cats is a federal violation. With that said, they will never know you removed it. Of course, I just gutted my stock one for free and it looks stock on the outside. There's very little to no gain in doing the 3rd cat. Not worth it unless it's free.

Some people have had good luck with the j-pipe and PCDs with stock exhaust. Most of the gains came from the j-pipe and PCDs more than getting rid of the stock exhaust and it sounds quiet but good.

 

Leo, you will pass emissions with the RV6 V3 Jpipe.

 

You always prove useful information . The R6 V3 J-pipe already get rid of 3rd cat. I don't know about PCDs but J-pipe sound good to me (as I read so far I think it's illegal). Will it smell without the 3rd cat ?

 

I just wanted to asked you that question about RV6 V3 yesterday. For some reason I couldn't send you message and I thought you was banned.

 

yes, was banned but back!

*edit
I have the RV6 V3 and will be going through emissions in feb.
I am very confident that I will pass, but will update you.

 

I'm glad that you back Justin. Looking forward for your good news

 

Not at all. I haven't had a 3rd cat for years and you can't tell the difference. It's honestly not worth the money, there are practically 0 gains. The 3rd cat flows a lot more than the primary cats. If you "gut" it like I did then it's free otherwise I wouldn't waste the money.

 

The "gut" is a good way to go, on my 240sx i did a gut and then welded a 2.5" pipe in the cat just so i get the straight through flow, didnt like the idea of exhaust swirling in the cat for some reason. Plus it was free since i have a welder.

 

You know, the word "gut" make me think back about the old Japanese .

 

Just get the RV6 v3 j-pipe, it removes the third cat, and it will give you pretty good power.

 

That what I mean above talk about no 3rd cat.
