Custom Built Full Exhaust On The Cheap

I had it dialed in pretty damn good just using Tuneboy and making changes myself and testing it over and over. Never had the time to get it on a dyno or I'm sure I could have gotten it a lot better. I had all the flat spots worked out though. Next setup I build I will definitely have it dyno tuned.

Niiice, do you have any high res pics of your bike? Absolutely love this low mount.

Unfortunately, not any good high res ones of the exhaust side. Got some of the other side though. I parted that bike out awhile back after spinning bearings in 2 different engines. I've got an 08 SE now and I'm going to be building another header/low mount exhaust here pretty soon.

Just ordered my stock header today. Going to make this a good winter project but have some questions. I am planning on getting a coneeng collecter and putting that on and just welding in some SS pipe to get rid of the cat and run that on my comp werks undertail exhaust... but here are my questions.

A) What if I kept in the o2 sensor? would it help the idling problems you guys were having and/or help performance at all?

B) If I were to keep in the exup in that should keep the volume down at idle right but would it be worth the fab work to integrate it into the SS pipe ? also if I did this (keep the exup) would it take away most of the performance gains?

A) I removed mine since the exhaust is so short, but with you having an undertail I would probably keep the o2 and have them weld in a bung for it. With such a short exhaust the readings it was getting were not accurate.

B) Don't under any circumstances, keep the exup.

haha ok i'll chop her off! what are the negatives about it though?

[krause95]

Anyone out there know what size O2 bung to get and what threads?

Its for a 09 Daytona O2 sensor

Is it not possible to just cut the stock header right after the 3-2-1 merge? Instead of having to do the merge yourself.

You can do that but you won't get all the benefit of a merge collector
