yeah for a low-volume item, i’m not surprised they build to order. and they probably don’t have nearly the same volume as someone like magnaflow, where even if it is a low-quantity item, they make so many other exhaust systems that they can just spread out the cost over all the other units they’re running anyway.
i have no doubt on the quality of the JHM exhaust though.
^Agreed 1000%
it’s the only exhaust I’ve ever installed that required ZERO adjustment of the hangers to center the exits - direct bolt in and the tips were in the exact spot they were supposed to be…
I agree given the low production and initial amount of exhausts sold I think it only makes sense to build to order. The fit and finish let alone the time to build them is something that makes more sense to not have units sitting on the shelf and just wait for a customer to order one.
When you look at the other exhaust options or lack there of you notice that the 2.75" JHM exhaust is the only real performance exhaust.
I notice there isn’t a lot of talk about high flow cats or test pipes. Why is that? Anyone running straight piped with the JHM Exhaust?
The exhaust manifolds hold the cats. So you would have to pull the motor to get to the cats. The big talk is headers. They are made by a member on here and the just fucking destroy the hp thoughts.
One member on here got full exhaust with headers and he picked up I think 100whp and 100+wtq. that was with a custom JHM tune but it was impressive.
Ahh ok, makes sense. ~100WHP is insane gains for headers. Do i even want to ask how much those headers cost? On avg we tend to pay ~$100 per WHP, so by that logic these are $10,000 headers.
You would have to email CV countvohn on here. But from what I remember a full catback 2.75" with the headers was 7500
