Finally installed my FULL exhaust system on my '90 GTU and all I can say is BadAZZ. Climbs through revs faster and everything (but i'm sure any exhaust will be faster over a stock system with a clogged cat with exhaust leaks galore from all the rust. With all being said my only complaint is it's loud as ***. I hope to dyno it soon so i'll keep you guys updated.

 

I really want to get dual n1, but people make a good point about the single flowing the same or more air than the duel, also it's less wait. However, It does look like you only have one ******** instead of two

 

I wanted to go dual, but for weight, I am gonna go single. I love the N1! Good one! Any pics?

 

Sup man

I'll try to get some pics, as far as weight I don't think 15lbs will make a big difference. Thats how much the other muffler with the piping weighed. The only part that was really REALLY heavy was the RB downpipe and presilencer combo. Just the presilencer alone was pretty damn heavy. Anywayz this system is pretty loud. I honestly think any rotary with exhaust and straight pipe is loud no matter what "they" say.
