NA Test Pipes Noise

leestewart · 03-27-2005, 10:12 PM

Hey, was just wondering if anyone with a NA has test pipes, if so how much of a difference is there in exhaust noise. Not that it matters I was just curious. Thanks Lee

well you're taking out the most restrictive part of the exhaust when installing test pipes, so it will sound considerably louder, and may have a bit of rasp to it around 3k rpm... can be solved by putting in a straight through glasspack resonator, i did on mine and it worked wonders, then again, mine's a z31 so you never know what the differences could be.... mainly 1 pipe compared to 2 i guess....

delirious i didnt know u had a test pipe on your Z does it give it a better sound on the z31 cause tahst another one of my future mods lol

definitely louder.. gives it a bit more throaty of a sound... everyone who rides in the car comments on the nice sound of it... i got it done for really cheap when the guy was replacing my transmission... i'd recommend using a resonator or it will be deafeningly loud and probably rasp pretty hard with the wrong muffler.

i just hollowed the cat on my Z31 and added a mandrel bent cat back with some HKS replica muffler. its loud, really loud but not too raspy...just really really throaty and deep.

you should replace the hollowed cat with a piece of pipe k3... i've heard that even the shape of the cat causes some pretty major flow disruption... if you're going for performance that is

nah...i got myself wrapped in too many projects. i dont need to spend mroe money on that car, yet.

i just like pulling i on the weekend and putting it in 2 and just sitting at 3000RPMs as i drive through my neighborhood.

i was thinking about just sticking some stacks off the exhaust ports and running them right along the side of the engine and then cut a whole through the hood on both sides.

lol, now that would be LOUD.... i don't think people would like you for that lol

yeah i got a z31 that i just put a full straight through 3" shit i guess there will be more of them police evation threads lol hey you cant get a ticket if they cant get your plate lol well actually it is REALLY REALLY loud as f#$$ ya know i didnt think it was going to make that big of a difference i thought that the 2 1/2" was kinda mildly loud so what the hell ill go for a nice 3" straight through and io almost wanna say it was a mistake i mean its sounds so so mean but its loud but as for test pipes and a straight through performace muffler yeah do it hell go 3" straight and be loud and mean actually on that note i hade the exaust off just prior to the cat and started and it was no where near as loud as the 3" and i just thought of that its kinda funny i had approx 3' of 2 1/2" pipe on the car and now i got like 8" and some bends and it is louder than it was with 3' straight 2and a half that dont even sound right

for the starter of this post, when neogenious does post this link, keep in mind his will be alot quieter than your N/A, due to his turbochargers acting as a dam for air flow...
