Guys I decided to go with the T1r instead of the greddy exhaust I want to get the duel cause as much as I want power I want my car to look great. So now I have a question if I'm not going to go FI what should I go with 70mm or 63mm I will add some stuff to my car like intake headers and more but not FI so I need ur help IDK if I will lose power with the 70mm I like the 70 cause its loud I want the car to be loud I will be running test pipes. THANX for everything I really like the way you guys help I tried to search nothing could be found lol on what I needed.

 

Our cars have 4 cylinders and 1 exhaust system. You can only run one header and one test pipe.

You will gain power with the 70mm dual on any setup. Not nearly as much as a single though, maybe 6whp? It will be loud.

 

Thanx a lot dude cause i thought the 70mm was only for FI but just found some info that it is good if u have a lightly modded NA engine so I guess i will be getting the T1R 70R Sparrow. Once again thanx a lot

 

70mm will do you fine. Dont go for the smaller stuff.

go with 70RT, from what ben(aj-racing) said that's the far most quite and proven gain the most power

 

Of course he's gonna say that cause he sells them. In the end its just a pipe. The difference between 70mm exhauts is very minimal, maybe 2whp difference. T1R makes a very good exhaust and its mot obnoxiously loud. Much cheaper too.

 

ha you said quiet and t1r 70rt in the same sentence. and yes its prob the best exhaust for the price
