Maybe some more information will be helpful then.
We're talking tuned length (designed to make peak power when the factory cam does), mandrel bent with a 4>1 merge collector OR race-styled collector (you can remove the collector from the pipes) - in mild steel they will be cheaper than other quotes I've seen PLUS you get two dyno runs thrown in along with fitting. Stainless or HPC coated is just as easily available, the latter will require a bit more time as it takes up to a week to have them sent off, but still ends up being very competitive with other quotes I've seen for just mild steel.
I know a lot of you guys already have cat-back systems, if you don't we're happy to do a full system to your requirements when the car is in the workshop.
Sounds interesting that is for sure. So who is up to it?
