it sounds really badass dark and makes about 96 dba at 3700 rpm and is not going to scratch in higher rpms. i may be able to do a soundfile if you want.
price is around 970 USD or 800 EUR

Thank you guys for your replies. Yea anything is better than factory...most of the time. 2.5 in is sufficient i suppose (with duals) until reaching 500 bhp then make a crossover to 3in. Prob wouldn't be worth all the hassle of fabricating your own again tho. Might as well keep it 3in. since you already installed it. Read if you can keep it consistent until mid crossover pipe then you can drop to 2.75 or 2.5 to keep scavenging optimal also.

 

yeah i know, but was easier to make x-pipe merge with same size pipe, couldnt be bothered dropping the size and getting more pipe ordered, so twin three's it is

at the end of the day im happy, car is faster, just need WB sensor so i can do a propper tune

 

dont go down in size of your exhaust go up in horsepower to better utilize the bigger pipes haha

 

right wagnut good call lol

 

hahaha thats the plan, hence the 3 inch under there

 

hence, i have 3in mufflers on the end of my headers... so it back fires when i shift over 4k... AND? i like it and im free flowing enough for just about anything

 

If you get something other than Borla (if you get Borla, throw in a DMH electric valve in the flange), put in a No Weeds diverter -- then you will have a volume control on your exhaust and be happy no matter what.
