I have the QUAD exhaust and love it. My question is , does adding the midpipe add any more HP?. I really don't want to add the crosspipe due to a lot of the install issues I have read about.
I have the full GWR exhaust with the crosspipe.Know one has experience with this?.
Which should help, I would think, but there are other forces at work, too.When you delete the muffler, I think you loose some back pressure.
Though we are certainly happy to sell anybody the other midpipe....note another option is just having your local muffler shop weld in a 4 inch diameter resonator of your choice to the midpipe you already have.I did the non resonated as well and am considering getting the resonated mid pipe. It's too loud.
I hear you....Thanks Brian. Madness did the install here in LA. I can have them add a resonator. I am pretty happy with the exhaust overall. It definitely improved the response of the car and I have no intention of changing it out. It also sounds great in the canyons and with the roof down, but on long trips on the highway with the roof up is where it bothers me most.
The noise issue has more to do with what I want. I had a Lotus Elise last, which was a track car first and road car second. I swore to the lady I would build something more streetable this time.
