have an exhaust question....please help
i went to a local muffler place and asked if they could "custom" build me and exhaust for my 8......the aftermarket ones online are just too expensive for no hp gains........when i went to talk to them, they refused to do it, because they said that these cars have a backpressure issue, and if you do an exhaust and don't get the back pressure right.....it will hurt the cars performance ????
anyone know of this ???? thanks |
go to a different shop
|
i've been to these guys several times for the different cars i've owned....and they are really good......but the first thing they asked was that it had the rotory right ?
|
Most of the "backpressure" will be in the stock manifold, CAT and midpipe. By the time it gets to the exaust...it isn't really an issue per say. Length will make a difference I think
|
Somewhat disagree. I had my exhaust off completely for a few days and noticed the lack of back pressure. It was like I pressed on the gas but didn't have anything behind me pushing me. I don't think it's rocket science as to what type of custom exhaust you need, I think any exhaust will help with the back pressure. I don't think you need a special one. Go to a different shop.

You do realize that even if you took out the mufflers completely you are only going to get like 4-5 hp. Racing Beat already tried this.
|
Maybe they were confused and thought you had a turbo. If so, they probably didn't want to run the risk of detonating your engine.
|
i'm not to sure.....i'm not looking for any horsepower gains........just want some sound....
|
if you want sound and don't want to spend any money...try gutting your stock exhaust by taking out all of the baffle....
|
if u want sound... just changing the muffler can do that and would be much cheaper.
i think i saw on a midas commercial about them doing full cat backs for like 200 dollars :D mayb theyll do it on the 8? |
ya, thats all i wanted was to maybe weld in two new "flowmaster or magnaflow" free'er flowing mufflers.................
|
Or gut you cats. That will give you a louder sound & more hp...it also may set off your CEL & is illegal but it will definitely make it sound louder.
|
Drill holes in your muffler, it'll give you tons of sound!!!!!
