Top Speed Exhaust Fitment Q

[07Zroberts]

I was just curious if anyone knows if theres any fitment issues with the top speed exhaust on the hr motor. I heared some exhausts dont work and just want to make sure before i buy it. Top Speeds website says it fits 02-up but I really dont trust some of these websites. Thanks for any help

I got that on my 07 and it seems fine, it does rattle on cold starts just a bit but other than that the guy who installed it said there was no problem.


oh and have fun with that exhaust cause its LOUD!

thanks for the help but im sure it cant compare to my exhaust on my sti that rattles my house when i warm it up in the morning lol. Could you feel a power gain at all?

[t-350z]

yea i also been interested in this exhaust. how much lighter if you guys know over stock exhaust?

[350Z FTW]

Not really, not much if any power gain, it just sounds sweet, my friend says it sounds like a ferrari on the freeway

lol I know it truly doesnt, sheesh

[t-350z]

this exhaust doesnt get power gains? hard to believe

[350Z FTW]

I didnt notice any big increase, never dyno'd it so I cant tell you for sure, someone should thats for sure.

[t-350z]

shouldnt from a exhaust lol : ) someone chime in

[JSia]

its way lighter than stock .. maybe thats why people feel the difference? LOL

[t-350z]

anyone wanna show what power gains they got?

[07Zroberts]

just installed this exhaust about 3 days ago and love it. i got a hell of a deal on it too. the only problem we ran into was loosening the bolt that connects the cat back to the y pipe. other than that it was smooth sailing. highly recommend this exhaust for people who want that perfect deep tone that isnt raspy what so ever.best sounding exhaust imo. even my subie friends were impressed

had it for a few months on my 07. Sounds MEAN & DEEP as hell. however the drone at 1.5k~2.5k was just wayy too much for me so i had to switch to another exhaust. not sure on power gains though never dynoed it, but IMO it is the BEST sounding exhaust out there.

isnt top speed the weakest exhaust? It may be loud but it sucks from what i've read from other posts.

not from what I've read. Apparently it provides better gains than most exhausts because its all straight piping

I dynoed 277hp @ the wheels with my rsr exhaust

stock hr's thrown down about 260-263 @ the wheels ?

so at the most thats a 17hp gain just from the exhaust which isn't really that bad at all.

i have the 2.5"

and i also have the altered atmosphere y-pipe as well

i do have the sheet i just dont have a scanner...... ill bring it to my boys house and see if i can scan it there tomorrow or something

Without having a pre/post dyno from the same shop same day its hard to compare, much less same shop different day or different car different dyno, etc.

It could be a 4 hp loss for all we know...

[t-350z]

which one you think is better to get , 2.5 or 3?
