Exhaust Curiosity

[wilorichie]

I was reading someone elses post about exhausts... Just makes me wonder... Is mine the right size

I'm not to cluey about mechanics, but I do understand how pressure works with the exhaust.

I got my exhaust done at Right Price exhausts at slacks creek.

I went in and wanted my original exhaust replaced becuase of the non-turbo exhaust clangy mentaic rattle sound.

I said I wanted a quite sports exhaust... only just loud enough to notice its a sports exhaust (sorry guys, I like the low rumble hehe)

I drove out with a blasting exhaust which broke my ears. Took it back and they said they replaced the front muffler only and it sounds niicceee as now... perfect... Quite rumble.

Anyways, what I'm actaully asking is, what should the exhaust feel like. If I'm driving at about 3000 revs and take my foot off the accel, the car drops in speed quickly and the exhaust becomes even louder than when I am accelerating (sounds cool hehe). When on the highway in 5th gear, take the foot off the accel, again drops quickly. It feels like my exhaust is to small or something. My old commodore would just roll if I took my foot off the pedal on the highway so it just feels different.

My receipt says:

Muffler Sports 2 1/4" O/C Baffled 14"

Stainless Tip Twin 2 1/2" S/Cut R/In

Exhaust Tube 2 1/4"

That was when it was really loud.. I returned the car and they said "we have now also replaced the front muffler" with a holden Hq-Hz (Dual) is all it says.

How does all your exhausts feel when you take the foot your accel?

Is it manual or Auto?

If its manual.. than what your experienceing s knwn as "engine braking" and you have nothing to worrie about

ah yeh... its manual. My last car was auto, so I understand that it would put it in the best gear for no accel... but even if I have mine in 5th gear, I feel it drop massivly.

What revs are you at 100km? I sit on about 3k off the top of my head... I swear my old commo was at about 1.5 (I didnt have a rev metre/tacho)

thats because ratios r differnt. commodore and skyline gear box and diff ratios r differnt my vl sits on about 1700-2100 at 100km/h i think its at that rev range, but yer ratios.

Richie,

Any chance of some pics ? Would really like to see the mufflers used and general layout. Cheers.

Hm I don't have any pics sorry mate... and I can't really get under the car either. I actaully just realised today that my car didn't come with a jack =\

If you want specific pics I can try to get some... tell me exactly what you want and I'll do my best.

Also take into consideration I only love cars and when it comes down to it, I know nothing

Just grab a decent camera with a flash and put it on the ground just behind the rear bumper and take 1 pic, then put the camera under the cat ( facing backwards ) and take another pic. That should do the trick. Cheers.

If you're not sure where the cat is, is should be on the passenger side, in line with the front of the passenger side door.
