Sorry If I confused you. What I meant was that the mopar/borla exhaust is more restrictive than a 3" turboback because it is smaller in diameter, only 2.5". However it is larger than stock (2.25") exhaust but still only provides a small gain in power. If you have the cash go for a full 3" turboback exhaust which includes a downpipe + catback sections. This will help the exhaust flow more freely and allow your turbo to work more efficiently.

 

ah, that makes sense now. thank you very much for the info. that's exactly the type of knowledge i was looking for

 

But the borla still is a mean soundin setup and I went with it for my acr and also injen is a very nice intake way better than the mopar or aem or the rest . I loved both on my acr.

 

Check with your dealer on how they treat mods under the warranty. I've got the mods listed in my sign. and have had the car in twice for warranty work and did not get any questions or have to pay any $$. One of the issues was engine related and my only bitch was that I had to wait 3 days for the part.

One extra thing I did was to print out all the postings from this forum and the"other" forumthat showed my issue was a common problem regardless ofthe mods on the car and I presented the stack of papers to the service tech...............like I said, no charge and free coffee and donuts!!!

PS, if you go the M/B exhaust route, be prepared to adjust the tips a few times before they "set in".

 

great info, was there a noticable improvement with the k&n? besides sound, did yuo see any change in how it acted on the highway/open road?

 

after doing alittle research on modernperformance.com, i've decided to go with the K&N CAI with the mopar exhaust. save some bucks and see what i can do for installation. thanks for all the great insight everyone, and i hope to talk to you all again soon!!

 

are they really that rinky dinky are you sure you didnt get a bad deal on the exhuast?

 

i don't know. i'll find out tuesday when fedex drops it off. i figured they've had the parts for a while so they can just sell them for what they've been charging all along. unlike the dealer, who just decided to rake us by upping the price a hundred bucks. oh well, we'll see.

 

the parts came in last night, and i ripped into the boxes to check the merchandise. they all look good. brand new and shiney. so far so good. i've got a mechanic friend who's gonna help me with the install so i'll keep ya updated after i get everything finished

 

^which K&N intake did you decide on? is it the typhoon or one of the 'box' style ones?
