I've been researching this for several days now and have decided to go with the RV6 V3 for a little extra grin. My question is....I see that there is an increase in HP and TQ but what about MPG and Top Speed?

 

MPG - should stay the same as you're not burning more gas. But, might go down because of your tendency to want to use it/feel it

Top speed - should stay the same at ~130mph because it's electronically governed. You won't be blasting past that. I think you'll need to get the Comptech S/C to get up to that speed in a safe distance though.

 

I thought I read somewhere that the top speed was 150...I guess that was wishful thinking. I did have mine up to 135 once and it never shut down. Maybe my speedometer was off.

 

Jpipe,HFPC's, and Catback, then you'll notice a difference

 

my '06 6MT TL hits the speed limiter at 150 or 155.
I've never hit it tho

 

Just put my RV6v3 on Saturday. Reset the 'puter, and took it for a rip. Nothing huge was apparent at first, besides the improved pedal response really. After having started and driven it maybe 10 times since, and put like 200 miles on it, its very noticeable. Pedal response is better all around, and the car almost feels lighter in itself. And just the perfect lil added growl.

 

Stop contemplating, and just buy it/install it. Probably the easiest and simplest power mod and if you know your car well enough you will notice a difference in performance and sound.

Get the PCD along with the J Pipe for a more noticeable difference. Then deal with the rasp later on when you get to that bridge

 

Hence the tilde :-) It's +/- 20mph.

 

the auto's are limited at a lower speed.
I know for a fact that my '06 6MT TL stops at 150.
the type-s' are also limited lower.

couldnt view the vid, so i'm not sure where the limiter is on that specific car.
but by your comment, it probably reached 140-150.

 

Get the j-pipe, you'll thanks yourself later.

 

Rasp??? Haven't read that one yet? Does it occur when it's in a certain RPM band?

 

Only with the PCDs, not just a J-Pipe.

 

Here's what rasp sounds like:

sorry for not editing the vidz.

 

Just found this on one of your other threads....Very helpful- Thanks

 

I got rasp after I bought my J Pipe back when I still had my Greddy EVO II. A resonator fixed that but now I have it again when I got the PCD with a custom exhaust setup. It always happens at 3500rpm.

 

same happened to me, took about 150 miles for the ECU to adapt to the new mod. definately 4k-7k RPM noticeable, plus a slight sound.

this was my first mod on a 2005 AT base and I was very pleased. the install required some brute force and WD-40 to get the seized bolts off.

 

I find it hard to believe that removing 1 small cat would cause rasp... but that's just me being stubborn lol. I think 99.9% of the time, switching from the stock j-pipe to an aftermarket one will not result in any rasp. I think the fact you had the Greddy on there had something to do with your rasp.

 

^yes.

 

Dyno result?

 

Justnspace vs stock 6MT TL.

 

Just curious why your wondering so much about top speed? I mean when and where could you possibly safely go to the vehicles top speed? And even if you went to a track who cares that would be a one time thing and you get the top speed then have to stop right away. Your concerns should stick with HP performance. My C6 Z06 is rated to top out at 198mph stock...sure its cool to brag about but thats about it lol

From what everyone on this forum say the best bang for the buck would be the jpipe. I personally like the new RV6 V3 pipe. I actually just installed mine in my 07 6mt Type S this morning. Fitment was perfect, exhaust note did not change at idle, but you can hear a slight difference at about 2500+ rpm. Sounds real nice! Performance wise its hard to say as I only drove it once since then, but felt decent.

James congrats!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

ok so i recently had a cai and rv6 v3 jpipe installed on my 08 type s, and at first i noticed a slight sound difference which i liked. But now i am noticing that there is definitely RASP from the jpipe at about 2500-3000 rpm when i give it about half throttle. Anyone else experiencing this? starting to worry about a leak or something....

 

is it a rattle sound?

or a whistle, or hiss sound?

 

definitely more like a rattle sound. and my catback is stock fyi. for now.....

 

its not a leak.

I had the rattle sound as well.
I could never find the source, but i think its a heat shield or something vibrating.

 

at least when i got full throttle the raps isnt there.

 

Justin's on it... I cant believe I went so long without a J-Pipe... well worth it.

 

idunno, I always thought it sounded like metal vibrating.
maybe a heat shield.
as soon as i get my car up and running, i'll test out somethings.
actually my jpipe is off the car right now.

 

Did you ever get it fixed? I bet you did

 

Holy batman thread revival

 

Is it best to revive or start a new thread where people have addressed it over and over? lol
