specific to inline-6 engines? is the v8 the deal-breaker on quads?

looking to get informed before making any moves..

Looks great! Thanks for being patient with it I hope the exhaust looks better than it did on the photos, soon as you get more photos, we'll use your car as the car on our site that defines the product:

The current photos show the straight cut, last minute we decided to do rolled tips because they looked better and more finished.

they are 83mm inside diameter but overall diameter should be closer to 86mm with the rolled tips.

That's what the 3 local customers have stated, we had a dyno run on one of them, but he forgot to do the pre-install dyno run.

OP... looks like your passenger tip is little higher than driver side from that picture..
VID requested asap..!!!!!
Correct...

It's actually equalized in the exhaust chamber so you don't have that annoying single side exhaust smoke and grime while the other side stays unusually clean and never has any smoke coming out of it.

Installs for this shouldn't be more than $150, it's less than 30 minutes of work.

A sound video would be great, the final product is actually going to sound better as its broken in more.
