About to order Longtubes got some questions

[TerminatorSVT03]

I am about to order a set of ARH 1 7/8 longtubes with the 3 inch offroad x pipe for my 07 gt500 with a 3.4 whipple.
curiuos as to what others are picking up with a set of longubes and a whipples. Also if other people have a similiar set up if you could post exhaust videos that would be great! and what are you guys doing with your over the axel pipes since they are 2.5 inches and the x pipe is 3'. any help would be great

Expect 20-30 rwhp/rwtq gains and loss in psi at least 1lbs.

American Racing Headers runs the 1 7/8th header into a 3" collector, the off road pipe connects to the 3" collector and then after the X pipe ARH necks the off road pipe down to 2.5" to mate up with your over the axle tubes (aka stock cat back system)

You also have the option of an off road H-pipe which has a very deep tone and throaty sound where the X is going to be a little more raspy. I've got ARH long tubes in stock as well.

Oh ok cool I've been wondering about that lol wonder if it effects power that much not having a full 3 inch exhaust

Is there a specific reason your going with ARH? I don't have an opinion either way, just curious why you picked them over Kooks/Dynatech etc. I've heard 30-40 rwhp is expected. I have Kooks 1 7/8" with off road X going on as soon as I get a nice day to drop my car off.

Logistically it can inhibit air flow through the 2.5" reduction. The cool thing is that if you ever did buy a 3" axle back it's not difficult to take of the H or X pipe and have a muffler shop enlarge it back up to 3" to work with a larger axle back system. The higher you go up in boost the more of a restriction it can become.

A couple reasons why folks choose American Racing Headers. They are certified 100% Made in America. They are the only header manufacturer with that certification. Another reason for choosing American Racing Headers is that their 3" spiked merge collector is a known commodity to help increase horsepower through the collector. Knowing you're buying a product that is 100% Made in America is simply something not everybody can provide. Here's a link to the organization that certified American Racing Headers and the rigors of what it takes to get certified.

My tuner is suggesting arh longtubes and have always heard great things about their products. Hoping to pick up some much needed power and trq. And more importantly make the car breath easier lol

 

[TerminatorSVT03]

Also heard that kooks fitment wasn't as good as arh but I have no personal experience with either of them lol.

I have kooks LTs changed the cars sound completely.

My setup is Dynatech longtubes, Dynatech off road H-pipe Dynomax resonators.
I tries the Borla mufflers on my car, lasted for maybe 5 miles. wake the dead loud.
Went back home and re-installed the stock mufflers.

When I addad the longtubes to my car, with no other changes I picked up 35 rwhp 31 rwt

Dynatech hpipe? I have only seen their xpipe.

VMP sells some adapters.
You use your stock H-pipe weld the adapters on and they bolt up to the longtubes.
