So I ordered the Hahn intake/catless DP/ and TTR upper engine mount from ttr. Installation of all 3 took about 3 hours, but im not to great with tools.

Review

Install - Lots of pain in the ass bolts, otherwise okay.

Sound- amazing, actually louder then i expected but not crazy loud. At cruising speeds sounds stock.

Performance - In my brief drive it really seemed like I was hitting boost sooner, broke the tires loose pretty easily.

Vibes from mount- not bad, you don't really feel them at all, but it has shown me the poor quality of GM, i have some rattles to fix.

Rating- 10/10 Buy these mods. Simple.

 

you mean TTR?

 

Ya, ill fix that.

 

i had a 15 in extension with a pivot and that 3rd bolt was still a PIITA!!!!

 

Thanks for the review.

 

i really didnt have any problems with any of the bolts on my downpipe but i agree i have all three of those products and love them
