American racing headers 1 3/4

Plan on purchasing arh headers in 1 3/4 primary tube size. Found a shop to install and tune. Stock exhaust is staying going for sleeper. Also getting high flow cats. Only thing I'm not getting is high flow intake. Looked at afe momentum gt with pro dry S filter. Might be later. Know tight for headers but I think it's a good investment.

Re: American racing headers 1 3/4

Honestly, I know the stock headers look restrictive due to the bends and crimps but are they a restriction on the 5.7L engine? Not sure if you have a dyno where you can validate any differences in power or torque with before and after dyno runs but what's your reasoning behind you feeling this is a good investment? Have you seen any data that you can share that shows aftermarket headers on a WK2 5.7L engine makes a difference.

Thanks
Michael Plummer

Re: American racing headers 1 3/4

My headers are installed and it made a difference in low end torque. Cruising uphill at 60 it doesn't downshift like it used to.

Re: American racing headers 1 3/4

Still need tune for it. Lots of work. The heads have to be removed to install headers. Does feel stronger than before.

Re: American racing headers 1 3/4

Cdgatx) Still need tune for it.
MP) Do you have a dyno to test? A tune may not be necessary if the gains are within the limits of the processor to add or remove fuel. If the headers added more HP and TQ, your A/F ratio will lean out. If the processor is within it's limit to adjust fueling to meet the "COMMANDED" LAMBSE, then no tune is needed.

* LAMBSE is the final commanded fuel mixture commanded by the Processor.

Cdgatx) The heads have to be removed to install headers.
MP) That's stinks and it makes the cost of installing even more expensive....oh boy.

Cdgatx) Does feel stronger than before.
MP) I appreciate your impression and I'm going to assume the headers made a significant difference in HP and TQ but it would be nice to see before and after dyno information.

In the end, thanks for sharing.

Hi Michael,

I'm getting dyno tune on January 23. Also waiting on diablo trinity tuner. Getting mds turned off. My installer said it would be good to have custom tune. He is going to do that for me.

Re: American racing headers 1 3/4

I am also interested on getting the ARH long tubes
Do they bolt straight on to the stock catback?
Do you know if they would fit the corsa catback?

It does not seems like it requires a tune tho

Thank you!

Re: American racing headers 1 3/4

Looking forward to any future updates on Dyno numbers before/after. How was the exhaust note affected? I am currently running no resonator, x-pipe, and dual magnaflow magnapack mufflers with 4" tips. I'm looking for a more aggressive, muscle car sound similar to the SRT.

Re: American racing headers 1 3/4

Yeah in case you've never heard long tubes with a full exhaust, yes they will absolutely affect the sound to put it lightly. Awesome sound but not subdued.
