Two boxes in same places as standard, both straight though with "straight line holes", pipe is circa 2.75" diameter from front to back. Noisewise you can tell it is nonstandard but is quiet at tickover and only show its true colours at higher revs, would summarize as grumble----growl----roar----bellow- with popping on the over-run.
Car has Phase 2 Superchip with K & N panel filter- I would definately say that the exhaust does improve the power, it also improves flexibility and will pull from 30 in top without any problem. |
