No rubbing on the passenger side on mine. I would say any brand will have this issue on some cars. The just isn't a lot of space in there.

Mine rubs hard on the left frame rail during hard right cornering. I have loosened the engine mounts and pushed the engine to the right and then tightened the mounts down. It helped a little but it rubs and vibrates hard when the engine shifts to the left and the chassis flexes. This Im sure is...

American Racing provides a small plug in resistor pack that plugs in where your original muffler valves plugged in. It is mandatory to use these or the drive mode selection will not function. Simple plug and play. I know this because I got one of the first set of A Racing mufflers.

Yes, I do now. I tried it without cats and for my taste it was a little raspy. It is a matter of taste. In the future I may try it without the resonators.

I am using the LUND canned tune with a N-Gauge device. My car has full ARH exhaust. Put down 495 RWHP 410 RWTRQ on 93 pump gas and with no issues so far. Power delivery and driveability are perfect.

Well, kinda, we treat it like a track. 90 degree day, US 129 (Deals Gap) back to back runs across the mountain. Probably needed to stop and let me cool too!

It specifies in the owners manual that coolers may be required for tech cars. Yes FORD knows the tech cars need coolers for heavy use, so do the consumers.That is why the R came with them. This is just a chicken shit frivolous attempt to blame an O.E. M. for the consumer making the wrong...

Baseline 457 RWHP 375 RWTRQ DYNOJET Im sure the dampers are there for a legitimate reason, noise, vibration, etc. Omitting them could be a problem that is undetectable to the ear or ass I suppose. I run the crap out of mine so if it is going to create issues I'll be the kind who will...

Also, the absence of dampers has not changed noise, vibration etc. There is no difference than O.E. I also have tried with and without cats. While I am using the ARH mufflers which could make a difference, without cats is a little raspy for me. Craftsmanship wise the ARH system is...

My 09 GT500 has full KOOKS system. For that car they offered the best fit, sound, cost etc. at that time. My 16 GT350 has the full ARH system. For this car ARH has the best fit, sound, and cost. I've dealt with both companies on various cars and various manufactures. I will assert with...

I have the full ARH system including mufflers. I am running the ARH cats as well. I did try it without cats but in my opinion the car was too raspy. The cats tame down the sound just enough and do not cost any measurable power loss. I might try no resonators someday but for now I am pleased.

I am considering upgrading my oil pump. Do any of you know how many hours it calls for? I am considering this as a preventative measure. I also have no warranty. I have a lift, tools, and talent to perform the swap with no issues, I was just curious about whats involved on this platform.

Engine safety exist primarily in the accuracy of the tune and nominal boost pressure. The static compression ratio of these engines is a limiting factor but does not prohibit the use of low boost pressure if properly fueled and tuned. Chances are my 350 will get some form of FI next year since I...

Agree, difficult o decide with current videos. I don't think Nick (ARH) sells more than one muffler for these cars. The sound quality is nice, real nice, just quieter than O.E. mufflers. I will post when I get time but as you know videos are tough to use as a method of deciding. No harm in...

I am glad to help. I really do not like the lack of ethics at this ford STEALER, I mean dealer. I'll try to get to the STEALER, I mean dealer to check out your ride. Heck, I'm such a supportive member I'll even take the R out for a thorough shake down run. Don't pay any attention to the lack of...

I have the ARH full system, no cats with the ARH mufflers. Not using a decible meter or any other measuring device the system is actually quieter with the ARH mufflers. The ARH system with the O.E. mufflers is actually louder. Now I will not go into sound quality because that is a matter of...

Best and fastest way to get to this point and further would be to hand it off to Jon Kasse racing engines and start writing checks, 700 plus is a phone call and a few zero's away.

Keep up the great work. I have had several 800 plus RWHP cars that would not stop or turn worth a crap. I bought the GT350 knowing all these bases were covered for a great street car except power. 526 HP is a nice starting point, but won't cut it for a fun street car that weighs 3650lbs. I just...

I have installed ARH full system on my GT350. The A/C area bolt is the tough one as you have discovered. I used S shaped gear wrenches.That alone is not enough, you can get the wrench on it but to turn it requires creative thinking. I believe I used a long extension to "push" on the s wrench...

Looks to be right in line with others on the corn. Mine put down 498 / 402 torque on 93 pump with full American Racing Exhaust and a preliminary lund tune on a NGauge. No I have not data logged and re-tuned, might be some left but for now it is safe and runs well for a N/A car at 3650lbs.
