Most exaust companies focus on wide-open performance numbers and not on the low-end. I ended up trashing my first exhaust system to go with one that had better low-end performance.
Also, it may be a good idea to swap out the MAF sensor for one that can meter the air better. The OEM unit can only meter within a certain range of air and you may be outside of that range if you have not changed it out.
If your exhaust is true duals, you may benefit from a cross over tube slightly smaller than the main exhaust pipes. This will give you some low-end back. |
I dont have true duals, just catback borla. I want to go with the true duals but need to purchase another cat. So that whats leading me to look into my options. When the trues are put on I will also add the "H" pipe in also.
I haven't swapped out the MAF sensor. Who sells it and do you have a part #.
Thanks lots!
