[quote=“the Shoe” post=54819][quote=“mcmmotorsports” post=54790]Few issues,
#3: Allowing someone to outsource the parts (ie, summit glasspack) and have an exhaust shop do the rest of the install, could create concern over one exhaust system versus another producing more horsepower. Experienced exhaust builders know how to find 1-2hp with a bend here and not one there or how the bend is made. That takes away from the equality or at least the comfort KNOWING there is equality.
Thank you for bringing up what is one of the issues. The “Spec” exhaust we are getting, are NOT all the same. We had three “Spec” exhausts next to each other at a recent build project (working on several existing Spec E30 at the same time) And we could see that the three were very different. They were all bought about 12 months apart, and clearly one of the exhausts was going to be putting out less because of how the bends were crimped and one of them had much smoother bends. thus there probably was a 1-2 hp difference as you describe.
So if the current “spec” exhausts produced over the last three years are not IDENTICLE anyway than why not either create a second producer so we have 2 sources or SPEC the exhaust parts and dimensions and let us build them so we are not handicaped waiting for an exhaust that is difficult to install and may need modifications to “actually fit” anyway and will probably inherently have a 1-2 hp difference anyway.
Still love this series and will promote it as the place to be![/quote]
Wow - very interesting. Sounds like spec is getting down to “must be round and silver and run the length of the car attached to the downpipe in some manner…” Yes, we too still love the series and continue to promote it as well.
