So I wanted to leave a little review of some trials and tribulations with the Borla TD exhaust. This was the first mod I did to my car beyond small things like a shorty antenna. At 1100 bucks new this wasn't a small purchase. Listening to tons of Youtube videos and reading reviews on this site and a few others, I locked in on it as I was trying to stay away from rice, and looking for some gains.

After installing it with Zero problems (perfect fitment) and no leaks from the H-pipe It looked great and it sounded decent. On the looks department the can looks way better from the back a lot smaller and more aggressive. I do hate that the exhaust goes out to the edge of the tips. I think for 1100 bucks they should have flared the exhaust tips out and tucked it into the nice shiny rolled tips, it would have looked better.

As for sound. I was disappointed. Like why the hell did I pay this much for this. I LOVED the notes coming out but, it was barely louder than stock. So I decided to pick up some test pipes. Many people claim excessive loudness, monster rasp, and O2 codes. I was hesitant and was thinking about HFCs. At 3 times the price I decided i would take a chance on the test pipes and picked up a set of z1 test pipes. At the time I thought it would be a decent combo. I called up Z1 asked if they had any experience with the borla and there test pipes. A guy named rod there told me yeah yeah we do it all the time perfect set up. So I bought them. After I got them in and on, I have a leak on both ends of them, due to much larger sized gaskets then what was needed. Called Z1 refused to do anything about it. (3 out of 5 orders with them ****ed up in some capacity so far only 1 was rectified) Come to find out because I was dumb. The test pipe is a 2.5" and the headers and borla are 2.25" (the gaskets were for a 3 inch system)

Even with a small and a large leak out of a too big test pipe, it sounded MUCH better. a little undesirable rasp at 3.2k-4.1k Zero drone unless in 6th gear at 47-51 MPH underload (accelerating) but its a booming drone, the woman loves it =) It also has a hiss under deceleration when in gear. other then that it sounds amazing. A lot louder but not to the point where I attract cops. Under 4k its fairly tame, but over 5k its a banshee. I have been running it like this even with the leaks for 6 months. Currently I have some new gaskets and a 2.25" test pipe set coming to finally fix that issue.

Recently I picked up a Injen CAI from a friend whos going greddy twins. I got an amazing deal on it I couldn't pass up. Everywhere on every post everyone says how you shouldn't get a cold air intake. How its not worth it and no gains. Well I disagree. First off the sound. It completely removed ALL rasp from the borla. All of it. It still as a hiss on decell. She purrs underload now, the time it takes from accelerator down to acceleration is a lot shorter, it just sounds meaner. This is how I wanted this car to sound all along. It hasn't been on a dyno, but on the top end 5200-7k where it normally feels like its falling flat, it feels a lot stronger.

Now I have a new test pipe coming in with proper gaskets, I have a motordyne spacer sitting on my desk next to me and i'm about a month out from picking up an MREV2. After thats it's headers and on to the tune. Then I can finally work on the suspension and exterior!

I plan on posting some videos on youtube soon I will update this post when I get them up.

 

your gonna like the way that 5/16th spacer treats you. gives the engine itself a more aggressive tone/small but noticable gain combined with your exsisting upgrades. as far as the MREV2, I couldnyt tell you. my 04DE is a non rev and not nessesary, or at least the way I understood. for your 06, that might be a different story tho.

Most important tho,... your gonna want a good tunning

 

if you can weld a magna flow x pipe instead of having that h pipe. car sounds a bit more alive. my car doesnt hiss under deceleration even with my kinetix hfc.
