New exhuast system AE111

[BZR4AGE]

Hi there guys. I've finally saved enough to get exhuast done.

The car is AE111 BZR with Lots of work done to engine (check my profile)
I am deciding between 2.25 inch pipe or a 2.5 inch. What do you guys think will work best with my engine mods?

I am planning to remove the cat, mendrel bend to a flowmaster delta 40 series muffler (as a resonnator) then to a HKS N1 tip.

Anyone knows where is a good exhaust shop around auckland who will make custom mendrel bend exhausts for a good price????

Also, should I custom make some extractors too?? I know is difficult to get good ones for 20V, but anyone know anyone good in Auckland?

The guys who worked on my engine says I need something like 4-1 extractors as my engine set up is best for high end power. What do you guys think?

Thanks for the input

Cheers

dont touch extractors unless you find some with dyno proof, most of them will lose power over stock.

I think you will need another resignator aswell

hi ace. so leave the extractors, and 2 resonator????? how about a flowmaster plus a coby??? and shd I use 2.25 or 2.5 inch?

you could ask what the shop can do about the 2-1 part of the exractors in the way of making it better flowing... but not changing the tuned length, pm'ed you more
